An efficient yet safe insecticide that works on over 50 different pest species and lasts for up to 3 months after application.
The manufacturer of Suspend SC is a well-known manufacturer called Bayer Environmental Science, which is one of the Bayer Crop Science LP divisions that pay special attention to the environment and creating products that won’t harm it.
Suspend is one of their insecticide brands that will help battle a range of different insects without leaving a trace.
The SC in this insecticide name stands for suspension concentrate (SC). Suspension concentrates are made by suspending particles in water or oil. This is a common and very popular liquid insecticide type used by most professional insect control companies. For this particular product, this suspension was done with water, making Suspend SC a water-based insecticide.
The active ingredient in this insecticide is deltamethrin. This is a synthetic pyrethroid insecticide, meaning that it attacks the central nervous system of insects. So, once it enters the insect, their nerve cells become overexcited, causing paralysis and death. Deltamethrin is one of the most common insecticides used in the world of insect control because it’s both efficient and safe.
It’s worth mentioning that deltamethrin-based insecticides play a key role in malaria control. These insecticides are very efficient in controlling malaria vectors, such as mosquitoes.
Unfortunately, in areas that use deltamethrin-based treatments very often, pests have been able to develop a kind of resistance to this ingredient. This shouldn’t be a concern in areas where these kinds of insecticides are only used every few months.
This insecticide is very toxic to insects, obviously. It’s also toxic to aquatic creatures, like fish. This means that you need to make sure that it doesn’t seep into any bodies of water where fish might live.
It’s safe for use around humans and pets, once it has dried after application. However, since it has neurotoxic characteristics, you shouldn’t use it around pregnant women or highly allergic people, especially in liquid form, since it could cause health problems for them.
The active ingredient makes up about 4.75% of this Suspend insecticide, allowing it to be efficient and long-lasting. It will work for around 90 days after application. And after this three-month period, you can re-apply it to extend its efficiency period.
It also won’t leave any residue or odor, which is great if you want to apply it indoors. This is especially true in areas where you store or handle food, like kitchens, restaurants, and so on.
Suspend SC insecticide will target a wide range of insects, starting with more common ones like mosquitoes, ants, spiders, and fleas. It will also treat termites, bed bugs, roaches, hornets, and so on.
Overall, this insecticide will be able to kill 50 different insect species, both indoors and outdoors. You can find a full list of all the species here.
Bayer recommends using a handheld or a backpack pump sprayer to apply this insecticide. You can choose to use other applying methods like a cold fogger, too. Make sure to dilute 0.25–1.5 oz (7.39–44.36 ml) of the insecticide in one gallon (3.78 L) of water, depending on how strong you want it to be. Once mixed, each gallon will treat approximately 1000 sq ft. (92.9 sq m). The product comes with 1 pint (473 ml) of the insecticide concentrate, so you’ll be able to use it for a long time.
Shake the solution once in a while during treatment to make sure it’s fully mixed. Wear protective clothing, glasses, and a respirator to keep the insecticide from getting on your skin or in your mouth or eyes.
After you’ve finished spraying, don’t store the insecticide in direct sunlight or places that get extremely hot or cold. If you do this, it will damage the insecticide and make it inefficient.
If you’re looking for an insecticide that can handle 50 different pest species and will be efficient for up to 3 months after application, look no further than this Suspend SC insecticide by Bayer.
Among its great features are the fact that it’s safe for humans and pets, leaves no residue or odor, and will last a long time.
Just 1.5 oz (44.36 ml) will be enough to make one gallon (3.78 L) of insecticide solution and spray a 1000 sq ft. (92.9 sq m) area. It would be hard to find a better insecticide than this.

How do you use it to get rid of mosquitos?
Insectcop
In the case of mosquitoes, the product should be applied as a residual surface treatment, directly to resting areas, such as walls, windows, ceilings, etc. As for the dilution rate, you should check the label.

Are there any possible health related side effects for people in general, and specifically pregnant females, occupying premises treated by Suspend SC (Deltamethrin)?
InsectCop
Deltamethrin is relatively safe to humans. However, being exposed to it still can cause certain effects. Getting it on the skin makes it feel like it’s itching burning or tingling, or just give a numb sensation for up to 48 hours. Inhalation can make you dizzy or give you a headache. Ingestion of large amounts might cause nausea, vomiting, abdominal pain or make your muscles twitch. If it gets in your eyes, expect it to be mildly irritating.
That being said, we suggest being careful when dealing with Deltamethrin.

Is this safe to use on vegetable gardens?
InsectCop
The label states not to apply the product to edible crops, therefore, vegetable gardens should be off-limits.
Nick
How long does it last in the sprayer after being mixed? What is the shelf life of the product before mixed.
InsectCop
The shelf life is around 3 to 5 years, just make sure the product is stored in a proper environment. However, we suggest using it within the first three. As for a mixed product, you should use it within 24 hours.

I am allergic to this and break out in a severe rash when it’s sprayed in my home. This last time I also got a staph infection in the rash and had to have medical treatment. sharing for others who may also be allergic. I have a recluse problem in my home and need to find a different pesticide that I am not allergic to.
InsectCop
We’re sad to hear about your allergies! Also, we suggest not using this product if you have had such reactions. Take a look at this article for some repellent options. There are some natural options as well, though, there’s no guarantee you won’t have an allergic reaction to natural ingredients as well. Good luck with your health and the spider problem!
