I have 2 bio active tank set ups with thriving ball pythons, some well rooted plants, spring tails and isopods. I've recently discovered that they both have fungus gnats in conjunction with the other critters, the gnats keep flying out of the cages and ending up in the rest of my house. I don't want to use mosquito bits in fear that it will kill the isopods and spring tails and I don't want to change the soil for obvious reasons, does anyone on here have any suggestions for getting rid of the gnats?
