So I put a terrarium full of VFTs in my office so that I could feed the houseflies to them that always seem to find a way into my office. And as often seems to be the case when humans attempt to control pest populations by introducing predators, there are unintended side effects. My problem is what appears to be fruit flies. There are hundreds of them in my tank now. They must be breeding in there. They pretty much stay inside the tank, but it looks ugly. These bugs are too small for all but my smallest flytraps to eat. I recently put several sundews in the tank to eat them, but there's no way these few sundews will be able to keep up with the number of these bugs in the tank.
So a couple questions:
1. Do fruit flies pose any threat to VFTs? Like will the bugs eat the plants or anything like that?
2. Actually, I'm not 100% sure they're fruit flies. They're small winged creatures that crawl around a lot and occasionally fly from one place to another. They sure look like fruit flies. Are there any other bugs I should be worried about that are about the size of fruit flies?
3. Is there any VFT-safe insecticide I could spray in the tank to knock most of them out without killing the VFTs?
4. Any other plants I could try that could eat a ton of these things? I only have about 8" from the media surface to the lid, so the plants couldn't be too tall.
5. Anyone else had a similar experience? If so, what did you do?
