Where Do Gnats Come From


Summary: If you have ever had pesky little gnats flying around your home you may have wondered where they come from and how you can get rid of them. We have compiled some information that will help you out the next time you suffer a gnat infestation.

Ever wonder what those pesky little flies are that buzz around your head? While you're busy swatting at them, you're probably asking where they came from and how to get rid of them. These irritating bugs can be classified as gnats. Gnats can be found in all sorts of places, the particular species depends upon location and source.

Fungus gnats are usually found near plants in or around your home. Plants are the best places for this species to reproduce exponentially because its eggs are laid in moist soil. Fungus gnats feed on fungi, but it also feeds on the roots of wheat plants and the tubers of potatoes.

The gall gnat actually lays its eggs in plants, as opposed to just the soil. When this occurs, large bumps form in the plant. These bumps, known as galls, often

signal serious health problems with the plant.

Non-biting midges can be found in any source of freshwater or in damp soil. This gnat spicies loves moisture because it feeds off of most types of vegetation that grow in water, such as algae. As irritating as these midges might be, the good news is that they cannot bite you. If they are in or near your home they may be a nuisance, but at least you'll be bite-free.

Biting midges have a different habitat than non-biting ones. They are usually found in mud, sand, or near decomposing plants. Female biting midges look for blood meals, but will also eat nectar. Kind of makes you want to rethink eating peaches.

Tips to Get Rid of Gnats:
• Instead of using peat moss in your plant soil, try using vermiculite. Fungus gnats are highly attracted to peat moss because of the large amount of organic matter it contains.

• Check the dampness of the soil in your plants daily. If you have noticed fungus gnats buzzing around them, they have probably already laid eggs in the soil. The good news, though, is the gnat larvae cannot survive in dry soil. So, allow the soil to dry thoroughly before watering again. Make sure not to wait too long, though, or you may accidentally kill your plants.

• If your gnat infestation is out of control you may want consider using insecticide on your soil. However, do so with great caution, as many plants

could get damaged by insecticides. Read the label to be sure you can use it on or around plants.

• If you do use an insecticide, make sure to apply the product to the soil once a week for about a month. This will ensure that if any gnats are not killed by the treatment, their young will most likely not survive. Talk about sticking it to the gnat.

• Try making a gnat trap. Take an empty milk carton and paint it bright yellow. After it dries, apply some sort of adhesive to the carton (like clear glue). Hang the trap near your plants or wherever the gnats seem to be congregating. Because gnats are not the brightest creatures on this plant, they will most likely be attracted to the bright object and get stuck on the carton. Granted, you will only dent their population, but if it makes you feel pro-active, go for it.

• Although this may seem like an obvious tip, make sure to keep your house clean to avoid gnat infestations. This includes taking your garbage out, washing dirty dishes, and storing food in pantries or cupboards on a regular basis. Think of a clean house as a gigantic bug zapper that will keep out a multitude of creatures.

• Some species of gnats may be attracted to vinegar, so setting up vinegar traps may help eliminate the bugs. Set out a jar of vinegar and poke tiny holes in the lid with a needle or other sharp object. Try to make the holes as small as possible so that the gnats cannot escape. You may want to put peanut butter or some other sticky ingredient on the inside of the lid. After configuring your trap, gnats will fly into the jar and will not be able to get out. They will either get stuck in the peanut butter, or will be unable to escape from the tiny holes. Say hasta la vista to the gnats for good.

My home is infested with biting midges and not able to get rid of them. I took some samples to the Entomology Dept at AZ State University, where they examined them and found they are biting midges.

I've had Younger Brothers exterminators come out and spray my house and bomb the attic, but I still have them. I am seeing less of them, but they are still biting me. I even have them in my car. We have shower about 3 times a day and also have to wash our clothes as soon as we take them off. We've clean and vacuum everyday.
Is there any known way of killing these pests permanently?
The biting is driving me crazy.

Thanks,
Bitten

The biting midge is associated with habitats such as swamps, still lake areas, lagoons, estuaries and tidal flats. If you live near any of these types of bodies of water there is little to do except keep yourself inside when the midges are biting.

Hello, I have an infestation around my home with gnats. I don't know what to do. I read your info and I understand. I don't have plants in every room, but they are in EVERY room. In all the windows there are 1000's. Can they come in from windows? or do they migrate from the rooms with plants to those windows? We can't eat without them attacking us.

They move towards the light. There are many species of gnats. You really need to get one properly identified to determine where they are nesting and how to control them.

Hi, I removed the house plants and the gnats in my home are gone. I took them all outside and started spraying them with insect killer for fruit and vegetable plants and I saw tons moving around in the soil. I saw white fungus all over one plant and realized that it was from the gnats. I don't want them in my house so I got rid of all but one plant. I moved them on my patio. HOpefully they don't die, but I really don't want them back inside.

I recently had a bout with them for a few weeks. I think the source was that they were laying eggs in the pet guinea pig's cage. We were cleaning it about twice per week and I think that was not enough. One time I noticed about ten of them swarming around the cage. Here is what I did:

1) gave away the guinea pig.
2) took all fruit in the kitchen and moved it into the refrigerator.
3) Took the garbage out daily and put fruit rinds in plastic bags.
4) Poured bleach into the sink drains for about ten minutes.
5) Took the two house plants outside.
6) Kept the counter tops and kitchen floor extra clean and the kitchen sink free of dirty dishes and standing water.
7) Bought insect killer and have been killing them one at a time.
8) Took a cantelope rind and some cheese and placed it outside of my window ledge to attract the gnats to the window screen. When I had several flying close to the screen, I closed the window and trapped them between the window and screen.

Hello.

I live in South FL. About 3 weeks ago I noticed small (ant-sized) black gnats gathering in my bathroom, in both the bathtub and the shower stall. Thankfully, they do not bite, they seem to be confined to the bathroom, and they have a short life-span. Unfortunately, the pouplation is growing and I am vacuuming dead gnats every day. I read some of your solutions, but I don't want to drive them out into other rooms. What would be best between the vinegar and pine oil solutions? Thank you.

the home I work in is infested with black gnats. the family keeps a dirty home, and I believe there is maybe 2 plants in the kitchen. I've never seen anything like this, there is up to at 500 at a time in this home. This filth doesn't seem to bother them. My question is what can I do to help and do gnats carry disease?
