Key facts about the wasp

The term “wasp” actually includes different types of insects. Indeed, the main species of wasp are:

  • common wasp (Vespa communis or Vespa vulgaris);
  • german wasp (Paravespula germanica or Vespula germanica);
  • the paper wasp (Polistes dominulus or gallicus).


  • Common wasp

Half an inch long (1 to 2 cm), it has a black and yellow-colored abdomen. Only an extremely thin joint connects the abdomen with the thorax. Its nest is a beige color.

  • German wasp

It looks very similar to the common wasp, and it’s difficult to tell the two species apart. One way to do so is to look at the patterns on the abdomen. A much clearer indication is the nest. If you have the chance of seeing one, you’ll notice that its definitely a grayish color for Vespula germanica.

  • Paper or umbrella wasp

Identical in length to its cousins, umbrella wasps differ from the previous two in that its silhouette seems thinner and the abdomen is sharper at both ends.


Wasp nests are more open than beehives. Wood is converted to paperThe social wasp lives in a community that can number up to 7,000 insects at its prime. Among them, only the fertilized females will survive the winter. In Spring, they look for an appropriate shelter to build their nest:

  • abandoned animal burrows;
  • holes in a tree;
  • cracks in rocks;
  • branches or twigs;
  • quiet cellars, broken gutters and even the occasional birdhouse.

Adults feed on nectar and other sweet liquids. Larvae, on the other hand, devour great numbers of insects.

Benefits of wasps for the gardener

Wasps are helpful in the garden to control pestsThe wasp’s larvae are what is most interesting for the garden. Indeed, their voracious appetite requires a continuous influx of all sorts of prey: flies, caterpillars, aphids, etc.

They thus are excellent protector insects for your plants and harvests, especially in the immediate vicinity of the nest.

Living with wasps in the garden

More often than not, the wasp has a bad reputation and people tend to avoid and even destroy it instead of attracting it. Nonetheless, it’s possible to cohabitate with the wasp, particularly when the nest is located high up in a disaffected portion of the garden. If the nest is high up, wasps won’t feel disturbed by our back and forths.

Trapping wasps with a sweet liquid isn’t a good solution. This is because it’s a wide-ranging trap that is non-selective. Many insects other than wasps are trapped, most of the innocent beneficial insects. It also won’t impact the wasp’s nest because there are so many individuals that picking off a few won’t change much. If you nonetheless want to try such a trap out, replace the sweet syrup with water and a few drops of dishwashing soap, and add something a bit meaty: a bit of cat or dog food, ham… Wasps find meat even more attractive than sugar and other insects don’t.

Lastly, if ever you must remove the nest for safety reasons, call up a professional. Don’t try to do it yourself.
