The answer to 'how did wasp get in my house' is that wasps can enter your home through cracks, holes, or open windows and doors. Wasps are attracted to food sources and may come inside looking for sweet drinks, pet food, or nesting materials. Common entry points include gaps around windows, vents, chimneys, or utility pipes.
If you find wasps inside your home, it's important to act quickly to remove them safely. Wasps can become aggressive when their nest is threatened, so it's best to avoid trying to remove the nest yourself. Instead, contact a professional pest control technician who can properly identify the species and eliminate the nest using the right methods and protective equipment.
