Hey /toy/, how do you deal with bugs and other pests?

I started collecting about two years ago, and I noticed that I've been getting springtails on the open shelving near some of my figures and media cases, not hundreds but maybe tens. getting in at a time. They apparently won't damage stuff but I feel like all bugs either shit or die on stuff.

I haven't been too great at dusting, I vacuum weekly though. I tend to only do a quick dust, should i be picking up and moving my figures every time i do?

I think it's worth noting that the only real space i have for my collection is in my basement. I was thinking investing in a dehumidifier or something might reduce pest levels or am i just fucked?
