Gnat problem

Our millipede seems to draw gnats. We completely changed his subtrate yesterday and we have the same problem again. The house is always clean , He seems to be the only pet that draws them. Any advice on eliminating the problem would be appreciated.

Have you tried burying his food in the substrate?

for our madagascar cockroaches at school we put a narrow band of vasaline around the top of the tank, and they get stuck in it. From time to time, wipe the old off (with the gnats in it) and put fresh back on.
