When you see new pests in your home, your first reaction is disgust, quickly followed by how do I get rid of this? And then, probably something like how can I keep this from happening ever again?
What they look like?
You’re likely to spot drain flies near sinks and showers that are stagnant for a time such as a guest bathroom or after a long holiday. Drain flies are grey or brown, leave behind a powdery substance when they are crushed.
How to get rid of it?
1. Fill a bowl or jar with equal parts sugar, water and white vinegar, then add 5 to 10 drops of liquid dish soap. Leave the jar next to the sink or shower drain overnight or up to a week until the flies are gone
2. Keep the drain covered with sticky tape or a drain plug at all times
3. Once or twice daily, boil a kettle of water, uncover the drain and pour the boiling water down it for at least a week or until the flies are gone
How to prevent?
Keep the drains clean and clear with proper pipe-cleaning maintenance because the drain flies feed on organic substance. For good measure, add half a cup of salt and half a cup of baking soda to the drain and flush down with one cup of white vinegar.
