Lana from De Soto, Il writes,

How long does Defense a Dust take to kill brown recluse?

We are dealing with brown recluse spiders. Tonight my husband caught one in a jar that was running around in our kitchen sink. He puffed Defense dust on it and at first it crinkled up like it had died but an hour later it was running around the jar like nothing happened. What's going on?


Delta Dust Insecticide can take minutes to hours to kill spiders. It has to enter through there follicles into their Central Nervous system.
