The answer to 'why is my wasp recurring problem' is that wasps can be a persistent issue due to their ability to build new nests quickly and their tendency to return to the same areas year after year. Wasps are attracted to sources of food, water, and shelter, and if these conditions persist around your home, they are likely to keep coming back.
Some common causes of recurring wasp problems include improperly stored food or trash, leaky pipes or standing water, and cracks or crevices in the home's exterior that provide nesting sites. Additionally, if you've had a wasp nest removed in the past but didn't properly seal or treat the area, the wasps may return to the same location.
