One of the hardest service calls to deal with is when wasps and other stinging insects have entered someone’s residence. When the nest is hidden the key is to find where the wasps are entering and exiting from. This means, during the daytime, doing a visual inspection at ground level to see if it can be determined from where the wasps and bees are coming and going. Focus on window frames, door frames, pipes, and other fixtures at ground level. Once you have identified the entry/exit point, mark the area and call your pest control technician so they can do the rest.
