Review of the Spectracide Triazicide Insect Killer For Lawns & Landscapes

Spectracide Triazicide is an insecticide solution used to kill and repel many outdoor pests.

The solution can be used to kill over 260 listed insects, making this a really universal solution.

We can immediately say, however, that it won’t work on every pest you can find in your backyard. For example, many users have reported the solution to be ineffective on ant problems as it only works only on specific species of ants.

For a list of all insects that the Spectracide Triazicide solution works on, read the product label.

Other than that, this is a really effective insecticide, especially for controlling mosquitoes and other insects.

Spectracide Triazicide comes in a 32-ounce (0.95-liter) bottle. The solution is concentrated and should be diluted with water before use.

As mosquito control, this insecticide provides long-lasting protection. After a successful misting session, you should have a mosquito-free backyard.

Spraying can be repeated after a few weeks to keep the mosquitoes away.

As mentioned before, this insecticide is made to kill all types of pests that live outdoors. It should be primarily used on the lawn.

The active ingredient in the Spectracide Triazicide insect killer is gamma-cyhalothrin in a concentration of 0.08 percent. Previously, the solution contained gamma-cyhalothrin in a 0.25% concentration which killed insects on contact, but for safety reasons, they reduced the amount of the active ingredient in the solution. However, this insecticide still works great for mosquito control applications.

The effects of spraying can last for 3 months, depending on the types of pests you are trying to eliminate.

This fogging solution is safe to use on vegetation such as plants, trees, vegetables, fruit, and flowers.

It also does not leave stains on most materials, but when misting around your house where there are different surface materials, make sure to test the solution in a small area to ensure that it does not leave any stains.

The insecticide comes with clear usage instructions.

And the company will refund your money if the solution is ineffective at controlling pests, which is a nice gesture and shows that Spectracide stands by the quality of their products.

What to use this product on?

Spectracide Triazicide can be used on many outdoor pests and insects such as mosquitoes, bugs, ants, fleas, ticks, grubs, crickets, worms, beetles, flies, etc.

The solution not only kills insects above the ground but in the ground as well. Again, read the product label for a more precise list of insects that the solution works on.

The solution will, however, only work on specific types of ants. Below, you will find an excerpt of the label with all the species of ants on which the solution is effective.

Where to use it?

Spectracide Triazicide insecticide can only be used outdoors. You can use it on lawns, vegetation, landscape, and other places outdoors.

Fogger compatibility

The solution comes as a concentrate and needs to be diluted with water before use. This means that bug fogging machines like ULV foggers and thermal foggers should be able to spray water-based solutions.

Remember to clean the fogger after spraying the insecticide so that it does not get damaged by the chemicals.

How to use Spectracide Triazicide?

Spectracide Triazicide insecticide comes with clear usage instructions that should be carefully read before use.

Here are some general rules for how to use this insecticide.

  • For the best mosquito control, a few hours before fogging wet the grass and make sure that the next few days won’t have heavy rain.
  • Mix 1.5 ounces (44 milliliters) of the solution with 1 gallon (3.8 liters) of water and put the mixture into the fogger.

When fogging make sure to thoroughly cover all areas where mosquitoes might be hiding including tree foliage, vegetation, long grass and dark or humid areas around the house and other places.

  • Don’t fog while it’s raining outside.
  • For best results, spraying this insecticide solution for the first time as soon as the insects appear is recommended.

The insecticide contains chemicals that are dangerous to humans and animals, so apply this insecticide with extra caution and do not allow kids or pets to enter into the fogged areas until they are completely dry.

Also, use protective gloves when working with any insecticide. Make sure to keep the solution out of the reach of children. And store the fogging solution in a cool, dry place.



Hi does this product after spraying on lawns need to be watered in.


    Hi Joe,
    No, quite the opposite, you shouldn’t let the sprayed area get wet at least 24 hours after spraying. But you can water the area you are going to be spraying beforehand for a better effect.


    Karen, Do you have to reapply the granulars after rain ?


    As long as the product has had the chance to dry before the rain falls, it should still work just as effectively.

    Lynn Dines

    Safe for cats ?

    Kristiana Kripena

    The label of the product says not to allow pets into the treated area until its dry, so the product should be safe for cats after it has dried.


What if it fell on my clothes and I dusted it off really good, wipes myself with baby wipes and then breast fed? Can it harm the baby?


    Since the Spectracide concentrate got on you clothes not on your skin, then you should be fine as long as you wash your hands and don’t let your baby come in contact with the area where you spilled the liquid.

    Arthur Oakes

    Can this product be safely used around the base of bird seeder if birds are not allowed until it has completely dry?

    Kristiana Kripena

    I wouldn’t use it on or around bird seeders since the product is harmful if swallowed and using it even near bird seeders might result in birds accidentally ingesting the product itself or its residue.


If you use the granules and the spray of Spectracide Triazide on same day can it cause seizures in small Chihuahuas? Thanks


    Hi Paula,
    This products along with Lawns Granules is harmful to pets only when wet. And if you use both the concentrate and the granules you give double dose of the Pesticide to your Chihuahuas. But as long as they don’t run around the treated area while it is still wet, you shouldn’t have any problems. (Although I cannot rule out that your dogs could be allergic to these products either.)
    I would advise you to use the products when you know it is going to rain soon, or water the treated area afterwards. This will not only make the products more efficient, as the active ingredients will get the chance to soak into your soil, but it will also wash the products off of the grass, making it completely safe for you and your pets to enjoy.

David Farrar

I have some granular grains of Trizicide I plan to spread it around my vegetable garden. Assuming this chemical gets into the subsurface, and thus the roots of my vegetables, is there any danger I a poisenig myself when I eat these vegetables?


    David, I wouldn’t recommend use the product around vegetables, because it does contain insecticide called Gamma-Cyhalothrin and therefore can be toxic to humans if ingested.

Susanne Shultz

Hi, how far away from my pond and stream areas should I stay when spraying this? Thank you!


    Since this product is in fact harmful to aquatic life, I would keep a good distance from your pond and stream, since you not only shouldn’t spray Spectracide near water, but you also shouldn’t let any runoff water that contains this product to reach the water.

    Idella McManus

    If birds eat this will they die? I had some near my bird feeders and didn’t read this until after. I raked a lot of it away. Also watered it. I know should always read. I hope they are okay


    The label doesn’t mention birds. It does, however, mention being harmful when swallowed, therefore, it’s better to eliminate the chance that anyone or anything could swallow it. But there’s still a good chance no birds managed to ingest it, therefore they will be fine. Just make sure to keep the spot clean and not treat it again by accident with something potentially harmful.


I used the concentrate hooked to my water hose but after covering about 3,000 sq ft TWO times the triazicide bottle is still almost full


I have a lot of birds in my yard. Is this product safe for them?


    Hi Patsy,
    Spectracide is highly toxic to both bees and fish (or any other aquatic organism). And even though the label of the product doesn’t mention birds, I would still use caution when using it around birds, because this product is harmful to humans and domestic animals if it is swallowed.

Aaron Campos

My mom was spraying it and some may have landed in her mouth will she be okay?


    The product is harmful if swallowed. I would suggest you call Poison Control Center or doctor for treatment advice. Have your mom sip a glass of water if she is able to swallow. Do not induce vomiting unless your doctor tells you to do so. And make sure you have the product label with you when you call the Poison Control Center or your doctor for a consultation.

Bryan Fauber

Why can i not use this product inside? Could I not dilute it down a little more and leave the windows and doors open? My children will be in school when I were to apply it and they would be gone 7 and a half- 8 hours.


    The reason why you shouldn’t use this product indoors is that it is harmful to pets and children if they get in contact with the product before it has had time to dry, absorb and break down. There are many other great indoors pesticides that are designed to be used inside. I would recommend you using one of them.


Can you use granules inside house to get rid of roaches


    The Spectracide Triazicide granules are not meant to be used indoors. They are, however, efficient outdoors to get rid of everything from ticks to fleas, ants, grubs, you name it.


    I need something for inside and not harmful to me and my kids.would you happen to know of anything i can put inside ???


    I would suggest you either try the Ortho Home Defense or any of the roach bite gels available in stores or online. They should help you get rid of cockroaches efficiently.


    My fiance thought it was okay to use the granules in the house in a small sot under the carpet because ants were there and then vacuumed it up. Will that spot be okay since he vacuumed the granules up? Should we be worried if pets are in that area ?


    As long as all the granules have been cleaned up, your pets should be safe around the area. However, do keep in mind that these granules can be harmful if swallowed, so you should probably also wash the spot, just to be safe!


im curious in how much i may have diluted my triazicde application?
i mowed yesterday, late afternoon 4-5ish pm. my sprinklers water on every even #’d days at 4am for a 10 minute watering duration, per section. weather has good days: 80’s to mid 80’s, evenings cool: high 40’s to low 50’s. your thoughts?
tks much!


    It is recommended that you apply Spectracide Triazicide in calm weather and let it dry for at least 24 hours before applying any water to the treated area. So if your sprinklers came on even for 10 minutes before the 24 hours had passed, they probably diluted it quite a bit. Mowing and temperature changes don’t really dilute this product.


What should I do? I put them around my vegetables. Can I still scrape them out even though it’s been wet


    I doubt you will be able to scrape it out. I suggest you wait at least 21 days to a month before you harvest your veggies after you have sprayed the surrounding area with Spectracide.


What is the shelf life of Triazicide concentrate?


    As long as Spectracide Triazicide is kept at room temperature, it should be viable for 3 to 5 years.


We have been treating every 3-4 weeks and we still have ticks getting on us. I just pulled one from my mother’s head (it had to have just gotten on her as it wasn’t engorged at all) and we just treated 3 days ago. Do you have any otger products that are more effective against ticks? This one was a brown dog tick, but we have also removed lonestar ticks from us. Does the spray only kill certain kinds of ticks?


    It states on the label that Spectracid should kill lone star ticks, brown dog ticks, American dog ticks as well as deer ticks. The recommended rate for tick infections is 6 fluid ounces to 1,000 square feet.
    But if you followed the instructions listed on the label of the product and there are still ticks in your yard you can try some other tick yard sprays that are currently available on the market. Vet’s Best Flea & Tick Yard Spray and Bifen XTS are good options to try.

Robin Sapp

I’ve been using this on my yard/trees/and plants for four years. I sprayed with the water hose last Monday and a couple days later all my plants/trees and lawn are DYING! I don’t know what’s going on but don’t think I’ll use this anymore. We have a beautiful, huge Rain Tree and it may be dead too. Praying it survives. Treating entire lawn with some iron and miracle grow in hopes of saving all this.


    Sorry to hear that this happened to your lawn and trees, Robin. Did you dilute it with water and used it in the proportions indicated on the label? Since this product is a concentrate it is way too strong to be used on its own and has to be diluted with water. For lawns, for example, adding just 3 tablespoons of the Spectracide Triazicide to a gallon of water will do the trick.

Brenda Sanders

Can the granulars be mixed with potting soil to kill bugs & eggs in soil when I bring my plants in the house for the winter and be safe for people & plants???


    The Spectracide Triazicide granules are not meant to be mixed in with soil. They are meant to be applied to the lawn or garden area and then watered in right after. Moreover, since you shouldn’t use the granules more than six times per year, I wouldn’t mix it with your potting soil.


Does this product get absorbed by plants, and then move through them systemically? Or does it stay in the soil?


    The label of Spectracide Triazicide says that this product is safe to use around veggies and fruit trees, you just have to make sure you use it according to the instructions. And as for if the product is systemic or not, it doesn’t have systemic properties, however, I would still be careful when using it around edibles and make sure that the recommended amount of time has passed between the last application of this product and harvest.

Nick Kahrs

I spilled some in my shoes. I blew them out with compressed air. Can I still wear them? They are leather loafers.


    Since this product isn’t hazardous to humans once it has dried you should be fine. Although I do recommend you washing or at least somehow cleaning your loafers before wearing them without socks.


I have been using this for 2 years now and it doesn’t seem to keep the grub worms or gnats at bay very well, any suggestions on what I may be doing wrong or something else I can try? I buy the concentrated version and use it in my sprinkler system with an RPZ approved for chemical backflow device. I add the concentrate every 3 months just to keep it in the system.


    If youŗe referring to the Spectracide Triazicide Insect Killer For Lawns & Landscapes Concentrate then your application method might be at fault here. This product isn’t meant to be used with a sprinkler system since the area needs to fully dry after application for the product to take effect. Only once it’s fully dry (it usually takes an hour or two) can the area get wet again. If it rains or the area is watered before the product has dried then it will lose its efficiency. Which is why you should apply this product using a pump sprayer or a garden hose if you buy the ready-made version not via a sprinkler system.


    …about grubs. MSU did a study and found this doesn’t work on grubs -at all. I was crushed because we’ve been using it thinking it was a preventative/control product. We love it for fleas and ticks though!!


If I spray this on bushes will it kill honey bees or wasps? I’ve read the label and neither are mentioned. Also, I sprayed this on my lawn yesterday around 3 p.m. and it looked like my sprinklers came on at 5 a.m. today, 14 hours later, even though they were set for 0 minutes. So, I have no idea how much water the yard got. Should I reapply and, if so, when?

    Kristiana Kripena

    Spectracide Triazicide is highly toxic to bees both if they come into contact with Spectracide while it’s still wet or the area that’s already dry. So don’t use this product in areas that bees might be visiting. Not sure about wasps, but I’d imagine the same thing goes for them as well.
    As for should you reapply the product, it’s recommended to prevent the sprayed area from getting wet for at least 24 hours because it will help to ensure that the water does not wash the pesticide off of the treated area. However, since 14 hours did pass since the application you might want to hold off on reapplying Spectracide so soon. After all, the manufacturer says that you shouldn’t apply this product more than seven times per year in each area.


I was at the store looking at the triazicide concentrate for lawns and the bottle had a hole in it and got all over my hands. I went to the restroom and washed my hands about 10 times, but by the time I had gotten to the restroom my hand was already dry. After I got home I took a shower and washed my clothes. Should I go to a doctor?

    Kristiana Kripena

    Spectracide Triazicide is only harmful if swallowed, so, since you already washed your hands thoroughly you should be fine.


Hey Karen & Others!
Wonder ing if this product kills kissing bugs/Triatoma’s? I know this kills beetles, but I am unsure if this is also good for the above mentioned?? Also what is the active ingredient?? I was told best way to kill kissing bug is with insecticides with cyfluthrin, permethrin, bifenthrin, or esfenvalerate as active ingredients. Thanks for the help!

    Kristiana Kripena

    The active ingredient in Spectracide Triazicide it’s Gamma-Cyhalothrin, which is a broad-spectrum pyrethroid insecticide. And since pyrethroids are one of the main insecticides used to control kissing bugs, Spectracide Triazicide should work on them.


Have a lot going on simultaneously in our lawn from fresh sod, 2 week young grass, new seed, fertilizer, weed control (non pre-emergent) and have to keep everything damp with 3-4 short waterings a day. We have dogs as well as grubs bad early in the season (may have been ‘root’ problem – lol). Luckily rain expected for few days in a row to save a bit of water. How do you suggest we apply? Any thoughts experience on Speed Zone weed application in conjunction as well?

    Kristiana Kripena

    Unfortunately, I have no experience with applying SpeedZone or combining it with Spectracide Triazicide, so I won’t be able to give you any advice on that. As for tips for applying Spectracide Triazicide, you should apply it after rain and once there is no heavy rain expected for at least a few days. And then reapply the product after a few weeks so the effects of it last longer.


Do I water my plants and soil before I apply

    Kristiana Kripena

    Yes, the manufacturer does recommend to wet the grass a couple of hours before spraying to achieve the best results.


Is Triazicide safe for oak, magnolia and crepe myrtle?


    The label says it can be used on oak. I’m not sure about magnolia and crepe myrtle though, so I would advise you to contact the manufacturer, Spectrum Brands, Inc.


I need to apply Triazicide Insect Killer for Lawn & Landscapes concentrate for chiggers in my flower beds and lawn. Should it dry on the plant foilage before watering it in so that it kills the chiggers on the foilage and in the ground? What is the best way to apply this for chiggers?


    For treating chiggers, the label suggests you mix 1.5 fl oz (3 Tbsp) in 1 gallon of water to treat 120 sq.ft. As for the foliage, yes, you should let the product dry before using water near it, or else it might lose some of its efficiency.

Renata chapman

hello, I used the concentrate with hose water at approx 4pm…it was dry out, warm. the next morning at 10am it poured rain for 10 mins. So the solution was on lawn for 18 hours and then rained …did I just waste my treatment or do you think it was ok? and….is it safe for my pet to go on lawn now with this info ? thank you


    Hi! It is recommended to use the product 24 hours before the rain, however, I believe the product would have had dried at that point. I also don’t think your pets are in any danger. But, if you have doubts, it wouldn’t be a bad idea to contact the manufacturers and ask them about it.


Does this product kill broad mites on ornamental plants?


    Yes, this product can be used to kill broad mites on ornamental plants.

Rose Ann Makowski

Does Triazicide insect killer also affect/kill birds?


    The label of the product doesn’t specifically say anything about birds. It does mention it’s toxicity to bees and fish, as well as humans and domestic animals when swallowed. I would have to guess that it might have the potential to harm birds.


Hi Karen,
My Yokoshima Cherry tree had little green caterpillar-like worms in a silk like web. So I sprayed Triazicide on all my trees. None of the trees are fruit bearing. However, I have a small 3′ X 3′ vegetable garden with tomatoes and herbs. I did not directly spray the vegetables/herbs, but, I assume the wind carried some of the insecticide to the vegetable/herbs. If I wait for 2-3 rainfalls, will the herbs be OK to eat? I did spray the herbs/tomatoes with fresh water after applying Triazicide to the trees.


    Hello, Paul! I suggest you try looking up the herbs on the label. However, tomatoes shouldn’t be sprayed 5 days prior to harvest.


Put Spectracide Triazicide insect killer for lawns & landscapes concentrate on back lawn. Took care of the insects however our German Shepherd became very ill (vomit, diahreah and no appetite). She was off the yard for 48 hours. How long should you keep your animals off the yard after spraying?


    The area should have been safe for your pet to reenter as soon as it has completely dried. However, if the product, for example, got into water your dog drank or on anything your dog ate that might be the reason why your pup got sick as Spectracide Triazicide is not safe to ingest.


How can you use this against Japanese Beetles without harming bees?


    This product is highly toxic to bees, so you should never apply it anywhere where bees might be visiting!


I sprinkled the Spectracide insect killer granules around the perimeter of my basement. An exterminator told me to use granules to kill crickets in my basement so I assumed these were fine but I’ve just learned that these shouldn’t be used indoors. They have a really strong odor. Is there any danger to breathing in the air? I wore a mask when I applied them but went down in my basement a few days later without a mask and breathed in the air.


    The label doesn’t mention indoor use. However, I’d assume a product meant for outdoor use only, might be harmful to human health. The product itself is supposed to be safe after it dries (outdoors), so generally the same might apply to indoors as well. That being said, if you can smell the product, it means its fumes are all around. Those might be dangerous, so the best advice I can give you is to figure out how to air out the basement while avoiding going there for now. Still, just to be safe, you can try contacting the manufacturer with your question.


Can this product be used for fly control in a horse pasture?


    The label says not to let animals or pets into the treated area until the product has dried completely. Therefore, as long as you can keep your horses away for about 24 hours, it probably won’t be a problem. However, just to be sure, you can always try contacting the manufacturer.


    Does this product kill red worms or nightcrawlers? I want to kill all the other pest but not these. I can’t find a product that wont kill the red worm or nightcrawlers.


    The product doesn’t mention earthworms in the label, however, there are some sources reporting that the product has moderate toxicity to them (one claiming to see 25% to 50% reduction of the population). You can see more findings in this article where they have tried many other products as well. Perhaps that will help you find the best option for you.


Hi, I put this in our yard and it killed the grubs over night. The yard is now covered with dead grubs. We have chickens that free range in the afternoon, should these be cleaned up before letting them out? Also wondering if it is harmful for our birds that visit the yard and eat them?


    The label doesn’t mention chickens (or birds) specifically, however, the product is dangerous if ingested which is why I would advise you to avoid having your chickens come in direct contact with the product.


If I just planted a garden can I use the liquid on it now? It will be at least two weeks before anything will yield vegetables!


    Read the label, different veggies have different time requirements. The product can be used on vegetables but you need to make sure to do the treatment for at least a certain number of days before harvest, you’ll find the specific time interval on the label.


What is the rule for applying the granules in the vicinity of a vegetable garden, fig trees, and mulberry bushes? Is there a waiting period before eating any of the produce, or should the product not be used around these crops at all?


    The label of the granules, unlike the concentrate, does not mention use in vegetable gardens or around crops. Therefore, we suggest not using them in such an area.


Is TRIAZICIDE toxic to yellow jackets. I’m using it for some other insects I have in the garden, however I just noticed some yellow jacks fly around my hedges. I also purchased the wasp and hornet spray.


    The label doesn’t mention yellow jackets but it’s highly toxic to bees, therefore, it’s likely to be toxic to them as well.


can i spray it directly on my tomato, buk choy, bell peppers, squash, cucumber, string bean plants? or just on the leaves?


    The product can also be used on vegetables. Just keep in mind not to apply the product for more than 5 times per season to corn and no more than five times per growing season on all the other crops.


I have discovered a large number of white grubs in our lawn and garden area. Put granules on an then watered down but it doesn’t seem to kill the grubs. If the grubs are up to 4 or 5 inches deep should this still kill them?


    If you’re following the label properly (apply rate, watering, etc), the product should help with the grubs.


I sprayed Spectracide Triazide on my rose bushes. However some got on the kale and squash plants. How long do I need to wait before harvesting them?


    The label doesn’t specify these two, though, based on the other vegetables mentioned, we’d go with 1 day for kale and 5 days for the squash. Though, contacting the manufacturers would also be a good idea.

asa strong

I put down granules yesterday afternoon when yard was still damp & did not water because it was due to rain in the evening. It did not rain…so if I water yard today will granules still be effective?


    They should be put on dry grass, then watered in immediately after the application. It’s possible they might still work but we wouldn’t give any guarantees, as it’s not as directed by the label.


i spread 320# of granules on 1.5 acres when jap millet was planted. the millet germinated and within 2 weeks, the field was flatttned by cutworms. I have used it previously with success, but not this yea
