Gnats — small, flying insects that sometimes invade your home and garden — are more than just annoying. They can damage plants and even cause health problems. Show
Not all gnats are bad. Some help pollinate plants and eat garden pests. There are four tiny, flying species commonly referred to as gnats:  Yellow Sticky TrapControl tiny fungus gnats that swarm around potted plants with a sticky yellow trap.

Gnats won't damage your house, but they can cause other problems. While all gnats bite, not all species have mouth parts that can penetrate the skin. Those that do bite through your skin can transmit pathogens and diseases and cause itching, redness, irritation and swelling. You may need to see a doctor if these symptoms occur. Fungus Gnat ControlUse a product with Bti, Bacillus thuringiensis israelensis, to kill fungus gnat larvae.

Gnats often breed in or hang around sinks, toilets, drains, garbage disposals and indoor and outdoor trash cans. Sometimes we accidentally bring them indoors on flowers, houseplants and fresh fruits.
Gnats reproduce quickly and in large numbers, so you may need to use more than one method to eliminate them. Try natural controls before you reach for pesticides or insecticides
Use a small saucer to mix a few tablespoons of apple cider vinegar, a few drops of dishwashing soap and a little sugar. Put the saucer near the gnats. Use more than one saucer, if needed. The gnats will be drawn to the sweet solution, fall in and get trapped. Replace the solution often, until they're gone.
Hang sticky flypaper ribbons to catch gnats, but be careful where you put them. They'll grab onto almost anything, including your curtains, hair and furniture. Don't use them outdoors, where they'll trap beneficial creatures.
Slowly pour 1/2 cup bleach, diluted with a gallon of water, down your drain. Follow by rinsing the drain with plenty of hot water. You can also use a drain cleaning product labeled for this kind of pest control; follow the directions on the label.
Put an overripe apple or banana in a bowl covered with plastic wrap. Punch a few holes in the wrap. Gnats that get into the bowl will be trapped so you can dispose of them.
Leave an almost-empty red wine bottle near your kitchen drain. Gnats that crawl inside to reach the alcohol won’t be able to escape.
Use an insecticidal spray made for indoor use.
If gnats keep coming back, or you have a serious infestation, call a professional pest control company for help.

Gnats are drawn to the color yellow and can be trapped on special yellow cards covered with a sticky adhesive. For best results, use small cards or cut larger ones into small squares. Lay them on the soil in your potted plants or attach them to twigs or skewers stuck into the pots. Once the traps are full, discard them in an outside trash can.
DE, as it's known, is an organic, abrasive powder you can buy to sprinkle over the dry soil in your plants. It will trap the gnats until they die from dehydration. Don't apply it when the soil is wet or it won't work. To make sure the DE stays dry, put some sand on top of your potting soil and then apply it. Water your plants from the bottom while using it.
Bacillus thuringiensis (Bt) is a bacterium that occurs naturally in the soil. Bt var. israelensis (Bti) kills the larvae of fungus gnats. Follow the directions on your product to make a Bti drench and saturate the soil in your potted plants. It will coat the plant roots without harming them and kill fungus gnat larvae that try to feed on them.
Let your plants dry out slightly between waterings so any gnat eggs or larvae in the soil will die. If your pots don’t already have drainage holes, make some.
If the gnats keep coming back, repot your plants in clean containers with fresh potting soil.
Keep gnats from getting in your home in the first place in by sealing up cracks, holes and crevices in your doors, walls, windows and foundation. Repair or replace window screens with tears or rips. Put food and beverages away after meals and clean up spills. Don’t leave pet food out and wash pet bowls daily. Check for leaks from indoor and outdoor plumbing and constantly damp soil around your downspouts or under your gutters. Clean up damp places where gnats like to breed, such as compost piles and leaf piles, and keep birdbaths, fountains and other water features clean. Use trash cans with tightly fitting lids and remove indoor trash daily. Keep compost piles and outdoor trash containers at least 15 feet away from your house. Keep fruits and vegetables refrigerated, not on the counter. (Some foods, like bananas, tomatoes and pears, shouldn’t be refrigerated so they can continue to ripen.) Wash fruits and vegetables before putting them away.
Instead of saturating outdoor plants with a Bti drench, drop a mosquito dunk labeled as safe for use around pets and wildlife in a watering can or bucket. Let it sit long enough for the dunk to release its insect-killing bacteria into the water. Pour the water over the soil of your outdoor plants. Do this for several weeks to be sure any gnat larvae in the soil are killed. Don't use electric pest traps for gnats because they often kill beneficial insects, too. Traps that attract gnats with ultraviolet lights may work, but they only trap the adults, so larvae are left to mature and reproduce. Some gnats swarm around outdoor lights. To discourage them, switch to yellow "bug lights" or low voltage bulbs, or keep lights near doors and windows turned off. If you get bitten but can't see what's biting you, the pests may be tiny, biting midges, also called sand gnats and no-see-ums. Avoid them by staying indoors on damp, overcast days when the air is still, or cover up when you're outside. Insect repellants and insect repellant clothing may also help. |
