- Product Review (submitted on May 3, 2016):
- I mixed in a sprayer according to instructions to prevent wasps from building nests in the ceiling of a gazebo and under the eaves. Also on shutters where the wasps like to go. I covered up head-to-toe as the product rained down on me when spraying the ceiling. So far, after about 3-4 weeks, no wasp activity. I am hoping that a single additional spraying in mid-summer will be sufficient.
