Yes to permethrin, but beware it’s very dangerous for cats. Don’t spray your clothes anywhere near them. Maybe keep any clothes you treat with it in a room they can’t reach, or sealed in a container—I think once it dries it’s less-dangerous but I still wouldn’t want one to decide to curl up on a pile of them.
I first heard about people using permethrin 5 years ago, but haven't looked into it too fully. Then I see this! There's likely some reason for it, Health Canada is known not to bow easily to corporate pressures, but I'm curious as to why.
Yeah I spray the clothes in the garage and let them fully dry out there. Everything I’ve read says once it’s dry there’s no issue, it’s only the liquid that’s dangerous for them.
