After moving some boxes from a storage unit to my house this spring, I'm now noticing these ugly spiders in my house. I've killed about 8 of them in the past month, and a vet friend told me they are brown recluse spiders. I want to spray, and heard that deltamethrin (Delta Dust or D Fence SC liquid) works on them.
I read the literature on the deltamethrin ( synthetic pyrethrin) and while it's not good for your dogs if they ingest it,It is supposedly not highly toxic. It is used in some flea collars, but as it's a relatively new pesticide *to me* I want some reassurance that once dry, this stuff isn't going to poison my dogs. Also, if you've used it on the nasty brown spiders, did it kill them? Thanks for any input. Now scroll down if you want to see the scary picture (shuddering)
