I came home today to find my poor spiders up on tippy toes. Usually this means the soil's too damp, but it's not, it's very dry. In fact the only moisture is the water dish. So I turn on the light to have a better peek, and gnats start flying out in swarms.
I found one cricket shell that had fallen behind the shelter, but surely there can't be that many gnats from one, and in 2 containers. The temperature in my apartment reaches in the 90's and I'm sure that has something to do with the amount of gnats, but what's the best way to eliminate and prevent these things without having to completely re-house my spiders (one's very fragile and I literally cannot disturb her until she's better).
