How quickly does the Delta dust kill spiders?
I have brown recluses I have dusted under furniture and behind appliances.
How quickly the Delta dust will kill a spider is dependant on how much dust the spider picks up on its body and the size of the spider. Typically dust can kill a spider in as little as an hour or as long as 24 hours or more depending on these factors.
