If there is one insect that has proven to be a nuisance to the human race, it is definitely the mosquito. These unwelcome health wreckers have mastered the art of vigilance like a military-trained intelligence unit.

You can hear them and feel their bites, but you cannot see them. They possess the power to carry deadly diseases and pass them onto humans. If you find yourself asking, “What can I do if there is a mosquito in my room?” then you are one step ahead in protecting yourself from these suckers. (Pun intended.)

For your great adventure, you will need a golden helmet, a sword from the River Zambezi, and one of Zeus’ thunderbolts!

I’m, of course, kidding!

It is actually quite simple to kill a mosquito in your house. While the challenge lies actually in finding it, you can still obliterate the insect even in its hideouts. Below, we will explain five ways to do so.

How to kill a mosquito when you cannot find it?

1. Use a mosquito net

Sleeping under a mosquito net is an extremely effective and cheap way to keep those bloodsuckers away from you, especially when you are facing an army of them.

Several species of mosquitoes are most active when we are asleep (dusk, dawn, or during the night). So, sleeping under a TREATED mosquito net is like having a divine shield of protection from the enemy. Your mosquito net will act as a barrier and the chemical on the net will kill those mosquitoes who dare to touch it. Do this for a series of nights and voila, the mosquitoes will either die from starvation or will leave to seek greener pastures.

2. Wear long pants and long sleeves to bed

Even though it’s hot in the summer, wearing long pants and long sleeves will leave less of your skin exposed. This means fewer opportunities for mosquitoes to bite you. If you kick your covers off in the middle of the night, you will still be better protected than if you wore shorts and short sleeves.

3. Use bug repellent

So, let’s say that you find a net somewhat suffocating and too bulky for your bedroom, which you should not since malaria and yellow fever are no joke. In that case, using any bug repellent for the bedroom is a good choice, too. These are applied to the skin, clothing, bedding or other surfaces and their odor discourages insects from landing on those items.

Just remember to only apply repellent to the topmost bedding. Do not apply them to your face, pillows, beneath the covers, or under your clothing.

Unfortunately, the use of these repellents, in the long run, will make you need to bathe more and wash your clothes and bedding more frequently.

4. Use insecticides

Maybe you want your room to stay as it is. And you want to apply nothing to your skin or clothing. Using insecticides will come as a saving grace in that case.

Most insecticides are made from pyrethrins or pyrethroids, which are products that attack insects’ nervous systems, causing paralysis and death. Pyrethrins are naturally derived from chrysanthemum flowers while pyrethroids are synthetic versions of pyrethrins.

Make sure to choose a product labeled for indoor mosquito control. These can be foggers, aerosols or sprays.

Foggers and aerosols release pesticides into the air. Everyone (including pets) must leave the house if you use such devices. Once the insecticide has dried, only then you can go back home, so make sure to check the label to find out how long you’ll need to stay out.

When you use sprays, you don’t have to leave the house, but you should not remain in the room once you’ve finished spraying.

Spray surfaces where mosquitoes are likely to land. They seek out cool, humid, and dark spaces, so spray in enclosed areas and behind and underneath furniture. Inhaling insecticides can be dangerous to your health.

We recommend wearing a dust mask or otherwise covering your nose and mouth while spraying. Keep children and pets outside of the room while you’re spraying and until the spray has dried.

Check the label for drying times. The World Health Organization recommends only spraying in emergency situations while some researchers caution against using insecticide sprays at all.

5. Use a mosquito trapping system

This option can be a bit expensive but may be quite effective.

Mosquito traps work by attracting mosquitoes with a combination of lures, often carbon dioxide, heat, and light. When a mosquito flies in for a closer look, a vacuuming fan sucks them into the trap interior. They’re either captured in a net, on a sticky surface, or are electrocuted by an electric plate or grid.

In tests, traps from different companies caught different species of mosquitoes at different rates. Therefore, your best bet is to read our mosquito killer reviews to find the ones that are rated for indoor control and have demonstrated effectiveness.

How to find a mosquito?

You can hear a mosquito buzzing around your ear. You find yourself thinking, “I have a mosquito in my house.” You turn on the lights. Boom. Nothing. This cycle can continue all through the night. Luckily, there is a way to find that tiny little terrorist.

Turn on a flashlight when you hear that telltale buzz. Put the flashlight directly on the wall so that the beam runs in a straight line across the wall. Watch carefully for any shadows. If the mosquito is on the wall, its shadow will be huge. (Physics come into play here.) You can also rotate the flashlight in all directions until you find the mosquito. And then obliterate that sucker with the palm of your hand or with any hard object with a large surface area.

You can also leave a single small light source on like a lamp and wait for the mosquito to approach it. It should land on the wall near the light source, where you can find it with your flashlight and kill it.

If you cannot find the mosquito use a flashlight or a cloth to disrupt its hiding areas. And then once you finally notice it, you can kill it.

The most common places where mosquitoes hide in your room are under and behind the bed or other furniture, inside your drawers, on the ceiling, or on the walls.

Or, you can also just stay up and wait. As I said, mosquitoes are attracted to carbon dioxide, heat, and light. So, shut off all lights and use your phone or tablet to browse the internet or to read a book. Do not wear any headphones, though, because your ears will be your biggest asset here. Eventually, the mosquito won’t be able to resist the light and carbon dioxide from your breath and will approach.

If it’s still staying away, try doing some light exercise. You’ll generate more heat and you might even sweat. And since mosquitoes love the smell of sweat, the mosquito will come flying!

How to keep mosquitoes out of your room

Getting rid of mosquitoes is futile without taking measures to prevent them from entering in the future. Here are simple things you can do to prevent them from coming back because these little pests never give up.

1. Grow some mosquito repellent plants

There are some plants that repel mosquitoes. This is also a good way to avoid using insecticides all the time as these plants produce a mild odor that mosquitoes find unappealing. Mosquito-repellent plants can also help make your house look more lively, be used as herbs, and are natural air fresheners.

Some mosquito-repelling plants include basil, lemon balm, lemongrass, lemon verbena, lemon eucalyptus, lemon thyme, peppermint, lavender, catnip, bee balm, clove, pennyroyal, citronella grass, marigolds, rosemary, garlic, and Venus flytraps (an insectivorous plant).

Aside from insectivorous plants, you can’t just plant a bunch of herbs and call it a day. They don’t repel mosquitoes just by existing. You have to get them to release their oils. This is fairly simple: just rub a few leaves between your fingers until they start to break apart.

2. Get rid of stagnant water around the house

Just getting rid of the mosquitoes in your bedroom is not enough. You must eliminate their breeding grounds as well.

Mosquitoes breed in stagnant water. The pupae transform into full adults in stagnant water. So, pour out any standing water that has pooled in containers around your yard.

If you have birdbaths, rain barrels, or potted plant trays, be sure to change the water weekly. If you have large water features, such as ponds or pools, make sure they are constantly circulating and keep pools chlorinated. Keep fish in your ponds to eat mosquitoes and larvae. For larger unintentional pools, create a path for water to flow out. But if you can’t remove standing water, add the bacteria Bacillus thuringiensis to it (this is easily done by placing Mosquito Dunks in the water), which kills mosquito eggs.

3. Trim the grass and bushes

Outdoors, mosquitoes usually hide in grass and bushes, especially when you chase them away from your house. So, getting rid of long grass and bushes or trimming them will take their hiding grounds away from them.

4. Keep your home clean

As with most insects, having a tidy, well-kept bedroom also prevents mosquitoes from hiding under the mess and therefore makes them more easy to spot and eliminate.

5. Don’t let them in

Finally, one of the best ways to keep mosquitoes from getting into your room is to keep them out of the house.

Make sure all windows have screens. The best screens to keep mosquitoes out have a mesh size of 1.2 mm (0.047 in).

Also, keep those screens maintained as any holes offer mosquitoes a way in. And, of course, cover or fill in gaps around doors and windows as these are also often used by mosquitoes to get inside your home.

My self and my two year old are getting eaten alive ,


    We have some articles that might help you, you can look them up on our page. Or you can go straight to reading our article about getting rid of mosquitoes to find various methods to choose from.

    Yeah. Mosquito season absolutely sucks.

Jacki Pauley

I have mosquitoes that come in the middle of the night and bite me. They have bit my fingers on my hand and last night they bit my forehead. I can hear them buzz my ears and I take a swat thinking I got it but there must be more of them. I am at a loss of what to do. I think they follow me when I go outside for a minute. Help any suggestions?


    You should take a look at this article. There are many options to choose from.

    Wear mosquito repellent at night and get a bed net. Get rid of ANY standing water. I had standing water in my toothbrush container and did not realize it. I found the larve growing in my cup. Disgusting!! Check all of your pipes to ensure they are not leaking. Close your bath drains at night in your bedroom. Mosquito do not travel far. Lastly, if all else fails; contact your local vector control. They will come and access your property at no charge. They found a creek behind my home infested with mosquitoes! I have been educating myself regarding mosquito for the last 3 years! Hopes this helps.


I’m in my bed right now and it’s 1:00am my mosquito net is being cleaned and there are three mosquitos trying to eat me alive here. I’m trying the flashlight thing to see if it will work but it’s just coming to bite ME instead of getting attracted to the light. What else I’m I supposed to even do at this point coz I’m tired and my head is paining. Usually at this time I’m always asleep. Help me please.


    In case you’re still in need of help, the easiest would be turning on a fan and turning it towards you, assuming you have one. Just make sure to be careful in order to not get sick. You can also try using some repellent spray, or just catch the mosquitoes and kill them.

I tried turning on a fan towards me…that did not work. However, the repellent spray and a bed netting helped.


The flash light idea works I found it on the ceiling and smacked it

I am also getting eaten alive! I think I am allergic, I got a blister the size of a nickel, filled with fluid! Gross! Lots of swollen bites and only 1 blister, so far, WHY? My husband never gets bit!


    This sounds rather interesting. I’ve never heard of such a thing before, to be honest. Though, is it possible that this particular bite was made by something other than a mosquito? Or are you absolutely sure they were all mosquito bites? You can also try consulting a doctor to shed some light on whether or not you’re allergic to mosquitoes. As for your husband, there are many reasons affecting whom mosquitoes choose, such as blood type, the amount of carbon dioxide produced, etc


the blister thing happens to me too, but only once per season usually. We produce a lot of antibodies in retaliation to being bitten. (That’s what my Dr told me once). I was also told that it is the amount of carbon dioxide we expel and our blood type (and that we have ‘sweet’ blood : / )


I got a mosquito (?) bite that was a small blister but had turned into the usual looking bite within 24 hours. The village where I live (in Bangkok) was treated to exterior mosquito extermination by a man using an implement that gives off a ’fog.’ but from that moment on we have been plagued by mosquito’s in the house. I can’t credit them with having a brain but it happened the same way last year. I use a fan during the night & rarely get bitten when asleep.


    To solve the problems in your room, you can give our article about getting rid of them a try.


I have used Avon’s Skin So Soft. I even have rubbed it lightly across my hair. I rub it on any body part that will be exposed. It has a slight smell to it. But I am very sensitive to perfumes and this does not affect me. The fan has to be strong enough to interrupt their ability to fly. If it’s windy enough they are too light to fly. A big fan is a good solution for outside.


I have been plagued by the little bandits as well!!! THIS ARTICLE IS VERY HELPFUL!!! I bought the “Lavender Fields“ oil from Walmart(about $2-$4) and I squeezed about 2 or 3 tablespoons into 2 small ramekins and placed them on the floor under my bed at the head. One on each side. It’s too early to say it’s really working but I slept fine the first night I did it. No bites!!! I’m gonna put out some more under my couch & loveseat where they bite me the most at while I’m watching T. V. Tip: use a warmer to burn lavender oil in your house. It helps!!!! GOOD LUCK!


It really helps if your hands are wet or damp if you are trying to sqish them – either with one hand or the clapping method… The damp/wetness makes them stick and really helps that they don’t slip away…


There are Aedes (also known as zika) mosquitoes in my apartment just north of San Diego, CA. Exterminators did not solve the problem as they sprayed insecticide where the flooring and baseboard meet. I vacuum twice a day and have used various insecticides, having sprayed all of the carpeting in rooms. The most effective insecticide I’ve used is Repel containing lemon eucalyptus oil. Do you have any suggestions. Thank you for all of the advice on this website; I know it has helped many individuals.


    We suggest looking into getting yourself mosquito screens. Mosquito screens on your windows will let you avoid them without being around chemicals, so in your case, it might be a great option!
