The answer to 'why do I have wasp' is that wasps are common pests that can build nests near or inside homes. Wasps are attracted to food sources, sweet drinks, and nesting sites like tree branches, eaves, and attics. Symptoms of a wasp problem include seeing wasps flying around your property, finding a nest, or getting stung.
To solve a wasp problem, you can try DIY methods like sealing entry points, removing food sources, and using wasp traps. However, if the infestation is severe or the nest is difficult to access, it's best to call a professional pest control technician. They have the right equipment and expertise to safely remove the nest and prevent future problems.
