DO NOT BUY!!! I placed the jug in the kitchen for awhile until I was ready to use it. It was sold to me as a refill, it did not have the sprayer attached. I opened the top to fill another bottle and roaches ran out of the bottle as I unscrewed the top so I dont know what they filled that bottle with. When I buy it from the store, Ortho is effective. This stuff draws the bugs and they live it.
