Last nite I killed a dozen black widows contained by my yard next to some poison spray. Many of them fell out of their webs onto the ground and died. I am worried my dog will step up to sniff them.

Can a black widow still deliver its venom if its already limp?
What type of flower is this?
Answers:    Why don't you just verbs up and get rid of the spiders? Anyway, animals enjoy a habit of sniffing through and consumption other dead animals or insects so i would not verbs about it, although the poison you used to snuff out the spiders may harm your dog depending on the strenght and volume you used.

Yes, if the dog eat them or chews on the. Better go out them and verbs them up. If I were you, I would've moved out away from the spiders untill someone kill them all for me.
