Review: Excellent product - I had a wasps' nest inside the vent cover of my ensuite bathroom, and it was becoming a real problem. I used about half a can, and it completely covered the vent in thick foam. Within an hour, there were no more wasps in sight. The product worked exactly as advertised—fast, efficient, and easy to use. Very impressed how quickly it resolved the issue. Highly recommend for anyone dealing with a similar problem!
