good useful product

it works! i have a lot of spiders due to the amount of trees on my property. They are always trying to get into the house. now that i use this product i have seen a great reduction in my home. it actually works as a barrier against the creepy crawlies. i have spread around the perimeter of my home outside an i squeezed it some of the cracks an crevices inside my home

Worked immediately on unwelcome termites!

Until I can get the Exterminator here I was told to try this in the corner where the wall meets the floor where I noticed some termite activity. Killed them immediately and I haven't seen any since. Still waiting for the pest control people.
