I have almost 1900 sq ft. Thursday I am bombing inside for 2496 sq ft. Underneath with 3 larger bombs and one in each shed and thinking of putting two in the big one just in case. I have used horse spray on spiders and they sure move out in a hurry. Also bee killer, the type that sprays 25 ft. Good for cleaning out an area you need to occupy or clean.Outdoors of course. I have read in this area that I should also get granules...thanks for that info. I dont do spiders.....may need to retrain the dogs to kill bugs....lol
Got a crawlspace anywhere?
Throw a couple fogger cans in there as well.
Just be sure ot wash all your dishes and such afterwards or you'll toxify yourself afterwards when you have dinner.
(Clean laundry should be put into some safe storage.)
