Wasps, Wasp Nest removal - Costa Blanca
Pest Control Spain
Signs are dependent on species, but most often the workers and the nest are the most likely signs. Despite the fear they sometimes evoke, wasps are extremely beneficial to humans. Nearly every pest insect on Earth is preyed upon by a wasp species, either for food or as a host for its parasitic larvae. Wasps are so adept at controlling pest populations that the agriculture industry now regularly deploys them to protect crops.
However in domestic situations, wasps will sting if they are (or feel) provoked. Sometimes just walking too close to a wasps nest will cause an attack.
