Pest Guide: Wasps.

The wasp is a predator that feeds on insects, spiders and other small creatures. It is known for its distinctive appearance with yellow and black stripes on its abdomen. Only the female have stingers, and the stinger does not detach when the wasp stings, allowing it to sting multiple times. Wasps are social insects that live in colonies consisting of a queen, males (drones) and workers. Wasp nests can have different structures and locations; they can be underground, freely hanging under roofs, or in various types of cavities such as birdhouses or hollow tree trunks.

Wasps are known for their stings and their presence often disrupts enjoyable moments with outdoor dining and drinks. Additionally, they can be potentially dangerous to certain individuals. Wasps and bees can resemble each other in appearance, but it is important to distinguish between them as bees are pollinators needed to support the ecosystem, while wasps are often considered pests.

Why fight wasps? 

If wasps have built their nest on or near the house, they should be controlled as they pose a danger to humans. Wasp stings can be very painful and cause severe allergic reactions in some people. When they build nests near residential and outdoor areas, they disrupt comfort and activities and can pose a threat to those with allergies.

Signs of wasp problems

There are several signs to watch out for to detect a wasp problem around your business or home. Here are some signs to look out for:

• An increased presence of wasps. If you notice a significantly larger number of wasps than usual, it may indicate that there is a nest nearby.
• You may observe wasps constantly coming and going from a specific location. It could be a gap in a wall, under a roof, or in the ground, among other places.
• High activity around food sources is also a sign. If you have many wasps around food waste, garbage bins and fruit trees, it is worth being extra vigilant.
