We recently noticed a high level of wasp activity in our attic and a nearby, unfinished, upstairs storage area. The two areas are connected and have an opening between them. I killed a number of the wasps but realize they are nesting somewhere in one or both areas. Each of the areas has a roof ridge vent which could be one way for their entry. Since it will be impossible to prevent entry to the areas in question, we are primarily interested in a deterrent of some sort that will render it unappealing to the wasps and other bees.
We offer a stinging insect prevention program. This service is typically performed every two months.
