2026-08-14 Gallura Disinfestazioni posted:

During the summer season, it's common to observe wasps and hornets in gardens and outdoor areas.

These insects play an important role in natural ecosystems, but they can become problematic when they build their nests near homes.

For this reason, it's useful to know the differences between the main species.

Characteristics of Wasps

Wasps are social insects that live in organized colonies.

They are distinguished by:

• slender body
• yellow and black coloration
• daytime activity

They build nests made of papery material obtained by chewing plant fibers.

Hornets

Hornets belong to the same family as wasps but are generally larger.

They can be recognized by:

• sturdier body
• larger size
• noisier flight

Hornets also build nests similar to those of wasps.

Where they build their nests

Nests can be built in various places:

• attics
• sheds
• trees
• cavities in walls

The location of the nest depends on the characteristics of the surrounding environment.

When to be careful

The presence of a nest near homes can increase the risk of encounters with these insects.

For this reason, it is always advisable to carefully observe outdoor spaces and identify any nests in the early stages of development.

Once the nest has been identified, it is possible to intervene with a targeted and effective disinfestation intervention.
