We had some tomatoes that got forgotten about and developed a swarm of fruit flies (or maybe fungus gnats) over the last week or so.
I tried the vinegar/soap in a bowl thing, it got some, I tried some of the yellow sticky traps, they have yet to catch any.
So, I went out and got a Black Flag bug zapper racket. It runs on 2 AA batteries and works great, I've probably gotten 2 dozen of them in the last hour.
Mike--We are also dealing with an invasion of fruit flies, and we, too, have found that the vinegar traps are only somewhat effective. Some of the flies look larger than the usual fruit flies. I'm wondering if I need to use larger holes in the traps.
Does the Black Flag bug zapper make a noise when you use it? I ask because our dog is very sensitive to sounds such as hammering, gun shots (hunting season and people target shooting is a problem here), or even the smack of a rolled-up magazine or a fly swatter.
Yes, it makes a snap and you'll see a flash of light.
I think I got 3 dozen of them first thing this morning. I think we're making a dent in them, but what we really need to make sure is that we don't have any produce out or other places where they can breed the next generation. Adult fruit flies can live 3-4 weeks, so it won't be an overnight cure.
I have also noticed that fruit flies find sourdough starters attractive. With bread dough, I think the yeast attracts them, so when the bread bakes, and the yeast is gone, so is their interest.
