There are two types of flies that show up in a big way this time of year, in Northwest homes: Fruit flies and Phorid flies.
Fruit flies like fermenting fruit. Phorid flies like rotting organic matter. Mmmmm, what’s not to like? And hey, doesn’t that sound kind of similar?
Fruit flies are found in garbage cans, recycle bins, empty un-rinsed anything which has had fruit juice in it, and on fruit. (OK beer is not fruit and they love fermenting beer – but it’s fermenting!)
Phorid flies are found in over-watered house plants, drains with organic build up, and areas where water accumulates, usually on a regular basis.
Tips to get rid of Fruit flies: Empty your trash daily. Rinse out your recyclables and keep them outside. If you keep an inside compost container, empty it daily and rinse it out. Consider storing your fruit in the fridge or inside brown paper bags. Consider making a nifty do-it-yourself Fruit fly trap. Google it. Vinegar traps work
Check your onions, potatoes, bananas, etc.. for spoilage and get rid of it.
Tips to get rid of Phorid flies: Over watered plants can be a problem. You can repot them into another pot that drains better, and you can set them aside until the moisture level drops, but there is a four week life cycle, so even if you let the plant dry out between watering, you can have some gnats. Rake the top soil of the plant as this will help kill fungus at the top of the plant. You can either remove the top few inches and treat it with an insecticide, or add a couple inches of treated soil to the top of the plant. (We can help)
If they are coming up out of your drain, you really need to scrub the drain line. Modern plumbing, with built in kitchen disposal units, often creates a thick viscous gel in drain lines that the flies breed in. Hot water won’t do anything. Bleach probably won’t do anything. The layer of slime needs to be physically removed. You can try a drain cleaner, but you may need to take a few things apart and use drain brushes to break everything up.
Other areas need to be dried up, sealed, moisture proofed – you name it, so that they remain dry and stop accumulating water and organic matter.
How can you tell which flies you have?
It’s not easy. Are they landing on the wall or on the ceiling – on the wall? You have fruit flies, on the ceiling? Phorid flies. It’s possible you could have both.
Can pest control help?
Yes, if you consider sanitation inspections, pest control. We do. Pesticides in a drain – not recommended. We can put enzymatic agents in there that break down soap and kill flies. It may not work on really badly slime plugged plumbing pipes though. We can spray dumpsters, and trash areas with both insecticide sprays and baits. These baits might help around your home – ask your tech if you would like your home surveyed for flies, your trash can lids treated, or for other helpful suggestions.Share on Facebook
