Life Cycle

The queen wasp looks for a place to build her nest after she is fertilized. Once she has built a sufficient number of hexagonal cells, she begins to lay her eggs. In 20 days, the adult wasps emerge. Although the lifespan of a wasp nest is no more than one season, it can contain 10,000 to 30,000 wasps.

Habitat and Food

Some species of wasps are well adapted to urban areas. Although they do not cause damage, wasps are often attracted to sweet substances such as fruits and juices. Nests are made in a tree or shrub, in the ground under a balcony, under eaves toughs, under outside stairs, in an attic, under a shed and behind the exterior wall cladding. Wasps live only one season and never use the same nest the following season.


Undesirable Effects

The female wasp can inflict painful stings. In case of allergy, these stings can even be fatal. Unlike bees, wasps can sting more than once.

Signs of Infestation

Just the presence of wasps around the home is a sure sign of a nest nearby. Their nests are made from a mixture of chewed wood fibers and saliva and are easy to recognize and find.

Preparation Steps for a Treatment

  • The AJS specialist will inject an insecticide directly into the nest, so make sure that you clear the space around the nest and that you are not too close. The wandering wasps die when they return to the treated nest or will leave if the nest is removed.
  • There is no need to leave your home. However, it is recommended not to approach the nest for 24 hours after treatment, and to stay away from the treated area.
