Review: Effective. - I am pleased with the effectiveness. After one treatment, there were only two wasps around on inspection this morning. I shall give it another go tonight. The only fault I found was that, for a continuous spray, the can needs to be held upright, which is impossible on ground holes... so I had to keep putting it upright every couple of seconds, and the force is not so intense. No big deal, I suppose. Review: IT WORKED totally eliminated the wasps and nest. - Thank goodness it did the job. We had a large wasp nest in our shed very dangerous in small space. Expensive but worth every penny NO MORE WASPS TO BE SEEN . ## Features - Causes serious eye irritation. - Contains PERMETHRIN (ISO).
