The answer to 'signs of wasp' is that common signs of a wasp infestation include seeing wasps flying around your home, noticing a nest or hive, and spotting dead wasps or larvae. Wasps can be identified by their thin waist, yellow and black stripes, and aggressive behavior. They build paper or mud nests in hidden areas like eaves, attics, or trees.
Wasps can be a serious problem as they are territorial and their stings can be painful and dangerous, especially for those with allergies. It's important to address a wasp issue promptly, as their numbers can grow quickly. DIY removal is possible for small, accessible nests, but larger or hard-to-reach infestations should be handled by a professional pest control technician.
