Wasps and other insects are more prone to build nests in conventional solid animal guards because they will be protected from inclement weather. Therm-A-Guard's open design allows wind and rain to enter the guard resulting in cooler operating temperatures of the protected equipment while also washing away contaminants that build up on the equipment. Of course, insects do not want to build a nest in this type of wet environment. Additionally, Therm-A-Guard allow linemen to easily see a nest prior to working on the equipment. Insect killer can be sprayed directly through the guard preventing insect stings to your employees.
