According to Natural News, gnats are attracted to warm, moist environments and decomposing produce. Swarms of gnats congregate in swampy areas, such as creek beds and soggy riverbanks. They are also attracted to rotting garbage and indoor pools of standing water, such as sinks full of dirty dishes and stagnant refrigerator drainage trays.Continue Reading
Natural News states that essential gnat prevention measures include washing and drying all dirty dishes, promptly drying laundered clothing and changing the water in pet bowls at least once per day. Household bleach is a powerful weapon in the fight against gnats. Adding a few drops to refrigerator drain trays and kitchen sink drip pans keeps gnats away and kills existing eggs and larvae. Flushing pipes with a solution of hot water and chlorine bleach kills gnat larva in deep hiding places. If the pipes have blockages of hair, food or other detritus, an effective solution is to use a foaming drain cleaner followed by regular bleach treatments.
Orkin Pest Control reveals that over-watered houseplants also attract gnats. Bleach is not an option in these cases because it is toxic to plants as well as gnats. To get rid of gnats in potted soil, gently mist the plant with warm, distilled water mixed with several drops of lemon-scented dish detergent. Blood also attracts gnats. Orkin Pest Control encourages homeowners to clean up spilled blood with a solution of hot, soapy water and bleach.Learn more about Flies
