The one insect I simply cannot abide is the centipede. Well, guess what I kept finding while I was turning over the dirt in a window box to get it ready to plant? Baby centipedes. EEEE! Is there something I can do to kill them in the dirt, ideally after I plant (cuz I already have the plants ready to go in)? I'd love for you to say something like "soak the soil with a baking soda/water solution" or something easy and based on household stuff... That would be awesome. But really, I've just got to get rid of them. Help? Thank you!
