There are several ways to kill drain flies, including natural DIY home remedies and store-bought products. Here are some effective methods:
-
Boiling water: Pouring boiling water carefully down the drain 1-2 times a day for about a week can remove both the drain fly larvae and any organic material built up inside.
-
Baking soda + salt + vinegar: Mix together 1/2 cup of salt, 1/2 cup baking soda, and 1 cup of vinegar. Pour the mixture down the drain, let it sit overnight, then flush the drain with hot water in the morning. This should kill all flies and the organic material they’ve been feeding on.
-
Apple cider vinegar trap: Create an apple cider vinegar trap using a small dish covered in plastic wrap. Poking holes in the plastic wrap will lure flies in but prevent their escape.
-
Store-bought drain cleaner: If you need a heavier-duty way to get rid of drain flies, try a store-bought drain cleaner like Drano or Bio-Clean. These chemical unclogging solutions will clear out the drain and pipes and help eliminate any materials or debris that may be creating a breeding ground for drain flies, thus preventing new eggs from hatching.
-
Commercial fly killer: Many common pest control killers, typically for fruit flies or gnats, can also be used to kill drain flies when the pests are listed on their labels. Since many of these contain caustic chemicals, check if you should keep them out of the kitchen area and be extra careful about damage to your drains. Green Gobbler is a popular fly killer that is safe to go down drains, septic systems, and even garbage disposals.
Its important to note that killing adult drain flies alone wont solve the problem, as their larvae may still be present in the drain. To prevent drain fly infestations, its necessary to keep all areas of your home dry and clean, especially dark areas where decaying, moist organic material can collect. Thoroughly cleaning and repairing drains, sinks, and drain pipes can also help eliminate the breeding ground for drain flies.
