Indescribly Awesome!!!

1st Of All! Would like it very much if this organization would make a larger quantity sized bottle of the same concoction formula but to include fleas, ticks, bedbugs, mites, etc! With a longer %26 lasting effect maybe 12 - 24 Hours or better? But besides that what it's made for...Me, mysef %26 I give it an 5 Rating!

I just got it last night. It's working. We are having a terrible time with roaches due to a flood disaster in the house. I have used a couple of other well-known sprays without any luck. I hit several directly with the spray. It also seems to be de tearing them I will know more tonight again, which is when they like to really get active but so far I really like this. I don't know if it comes in larger sizes if it does, I will be getting one.
