Flying invaders are a group of pests that are commonly found outdoors but may enter homes and businesses—often suddenly and in noticeable numbers. These pests are typically attracted to light, warmth, moisture, or seasonal changes, which is why they are often seen around windows, doors, and entry points. 

While most flying invaders do not bite or cause structural damage, their presence indoors can be disruptive. Many of these pests appear during specific times of year, creating short-term but frustrating infestations when environmental conditions are right. Understanding what type of flying pest you’re seeing is key to identifying where they’re coming from and how to prevent them from returning.
