Well, the other day I found another cricket in my bathroom. Inside the shower. While I was in it. With soap running into my eyes.
Apparently they're not so good at jumping when there is water raining down on them, so that little guy drowned. I dusted the edges of my apartment with the DE immediately after my shower. I don't think my homemade fly paper would have worked anyway. I put down a nice extra-thick line in the storage room adjacent to my bathroom because I'm pretty sure that's where they like to hang out and have babies. So far it seems to be working. I've only had one intruder in the week since I spread the stuff, and I think he snuck in through the crack in the front door because I forgot to shut it all the way behind me.
