Outdoors, gnats can break up an impromptu neighbor-to-neighbor chat session, ruin a good run and drive gardeners indoors in frustration. While gnats may be coming from some other areas near your property, there are a few things you can do to deter them from taking up residence on your property.
Remove all mold, fungi and rotting plant debris from your property, checking shady areas for poor air circulation.
Eliminate all standing water and keep birdbaths and other water features clean.
Improve your garden soil’s drainage and turn mulch at intervals to dry out moldy layers.
Introduce predatory nematodes to control gnat populations in your garden.
Keep compost piles as far away as possible from your home and securely cover all trash cans with tight-fitting lids.
Avoid over-watering plants and watering at night.
Controlling gnats indoors starts with not letting them inside in the first place. Because gnats are so tiny, they can fly through some screens. To avoid gnats in your home:
Seal cracks and crevices in your home’s foundation and around doors and windows.
Repair leaking faucets and any water leakage prone areas in your home.
Use only pasteurized potting soil in potted houseplants to avoid fungal attractions for gnat breeding grounds.
Avoid over-watering houseplants.
Store all fruit in the fridge and keep all food contained and food scraps properly disposed of in sealed waste receptacles.
Homemade DIY gnat control measures range from drawing gnats into jars or glasses of apple cider vinegar or red wine and wearing vanilla extract outdoors as a gnat repellant. You may consider purchasing a BTI product through a plant nursery to treat the houseplant soil.
