How quickly does the Delta dust kill spiders?

I have brown recluses I have dusted under furniture and behind appliances.

Answer:

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.
