Yo Snakeking, if you’ve got praying mantis chillin' in your pots, that’s a win they’re straight-up natural pest control killers. Now about neem oil yeah, it can mess them up if you spray it directly on them. Neem might not be full-on toxic like chemical sprays, but it still coats their bodies, and that can screw with how they breathe or feed, especially soft-bodied bugs like ladybugs. Mantis are tougher, but if you’re spraying weekly, even dried residue could mess with them over time.
Honestly, if the mantis are already in there doing work, don’t spray anything. Neem’s job is to kill pests but so is the mantis’s. So spraying defeats the whole purpose. Let nature handle it. Unless you’ve got a serious outbreak, just sit back and let your green guardians hunt. No neem, no stress. Let them feast
