I hate spiders so this is where it got me: pest control. I didn't really see any before I used them because I spray all the time, but I had a coupon, so I used them.
The guy was very professional. He sprayed the inside and the outside of my house and they had a guarantee so that if there were lots of spiders within like 30 days they would come back.
I it cost about $50 for the interior and exterior of my house.
