Drain fly maintenance tips: Drain flies are an annoyance; there's no doubt about that. These pests reach their height of activity from mid spring to mid fall.
Right now, in late June, they're at their peak. We do have a product called bio-drain which is effective. However, to get even better results here's some things you can do to get rid of them making the control success rate higher.
As the name would imply, drain flies come from the drain. Sometimes they'll eat fruit left out on the counter. This is why they're also sometimes called fruit flies. There's actually several different species - they're all basically treated the same.
Hair, toothpaste and lots of other waste debris will build up over time in the trap of the sink. Drain flies nest in this sludge. The first step would be to remove the hair.
We at Meryl's Termite and Pest Control are not plumbers. If you're not handy working with sink traps or plumbing in general, you may need to bring in a plumber or a handy man. The handy man would probably be the cheaper way to go. The picture to the right shows the sludge that needs to be clean out after the trap is removed. It's not a pretty sight but you can see why the drain flies would congregate here. It needs to be completely cleaned.
Next up for our Drain fly maintenance tips, we have the trap itself. Yuck. Again, you can see why this would be a great nesting place for drain flies. This must also be thoroughly cleaned. Again, if you're not sure how to disassemble the trap, find someone who can. Same thing goes with garbage disposals that haven't been cleaned in a long time. In the case of a garbage disposable, you will most definitely have to bring in a professional to clean it properly. Otherwise, injury or damage can occur.
It's not a pretty sight. The picture to the right shows some of the sludge that builds up in the trap of the drain over time. Once you take away the source of where the drain flies are living and breeding you're one step closer to complete control. At this time, we would come in and treat the drains with bio-drain also treating the sink and tub overflows. We can also set up fruit fly traps which should catch the remaining flies that may still be lingering around.
Speaking of tubs, they too can be a source for drain flies if they are used on a regular or semi regular basis. Depending how the drain is fastened will determine on whether or not you can open it and remove the contents of waste. In some cases, you can simply unscrew the screws and remove the strainer. Unfortunately, some tubes will not have this option. Bio-drain works best in such a situation. Drain fly maintenance should be part of any integrated pest management strategy.
