Sorry to bring this rather old thread back to life, but the subject is also very relevant here.
I have cleaned out all terrariums, used fine net on a frame of wood and set up two UV-lights, but still the phorid flies keeps coming back. I have heard they are difficult to get rid of. I got them in with a culture of A. tesselata, that was kept very, very humid.
Can lowering the general humid level help?
They can smell a dead roach through a platic box. If the corpse is within a closed container, the phorid flies will still assemble outside the box in dozens. I want to make a trap. Any good models or designs, that can be recommended?
The enthusiasm for invertebrates does not extend to phorid flies! My wife gave a good one, though: "Why do you keep them (phorid flies) in separate tanks? Isn't it better with one tank for them alone?"
She knew - just wanted to get me.... <_<
