fungus gnats in a bio active tank

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?

I had those in my isopod culture for a while and it was happening because there was too much freshly decaying plant matter. Resolved itself fairly easily just by not putting any newly dead leaves and only really old dry ones. In a brand new setup, you are bound to have plants with decaying leaves and things as the plants adjust and establish themselves. You could help things along by pulling some of the dying leaves, shaking off any isopods from them first.

You can try the bacteria BTI. It won’t hurt the snakes, but I can’t promise it won’t hurt springtails though. You can also put fly strips near the vents of the enclosures (not inside!!!!) to help catch some adults.

I second this. I have an issue with gnats and whiteflies because I bring my tropical plants inside in the fall, and they bring in their bugs no matter how well I try to clean them before-hand. The pre-scented pantry-pest traps seem to work really well for both types of bugs, but you can also find card-type yellow sticky traps that also work well.
