“I have purchased eleven bottles & have them all on my shelf. I have read all 115 reviews & they all without exception state that the verified purchasers of this product have found BugMD to work effectively. If you have a bad infestation you will have to apply this product multiple times. You have to find the nest(s), clean them out & spray the area thoroughly. Then you have to reapply, probably at least weekly. It requires a "full court press" BugMD style with ongoing maintenance., but once you clean them out & continue your maintenance cleaning & spraying you will be okay.”
