How can I kill off spiders without poisoning my monarch babies?
I have patio cement only and use cinder blocks for potted plants. I love and have monarch babies and I feel spiders are killing them when they get so big.How can I kill off spiders some black widows without poisoning my monarch babies. Driving me nuts. I have had total of 11 babies and only one that I can see is in her crystalis due to open in about 2 days. I already found a black widow under one of my caterpillars that was looking to ready herself for her crystalis and of course she was dead. Spider was fine. Thanks for any help.
