How to delete a wasp nest

In search of the wasp’s nest

Wasps can build their nests in the strangest places. Often, even before you see it, you realize that somewhere there is a nest because you see many wasps around: their path is always the same, follow them and you will also find the nest. The wasp nests that we often have to deal with in our cities are beautiful examples of architecture: they are made of wood that the wasp scrapes from trees, fences and old branches and with its powerful jaw chews to the point of reducing to a fine pulp. Once hardened, the structure resembles cardboard: in fact, this type of wasp is also called a wasp cartolaia. A large wasp hive can hold 20,000 wasps and is often found suspended in dry and not too busy environments, such as attics, garages, garden houses, old rat dens, but also the shutter boxes, the engine compartment of disused cars and piles of compost lend themselves well to the purpose.

Are wasps useful insects?

Wasps, unlike bees, do not produce honey and the contribution they make to pollination is really minimal. Negligible is also the competitor action that the wasp would have towards other small insects such as mosquitoes, gnats and the like: wasps much prefer fruit and sweet food to feed themselves. Moreover, unlike bees that die after stinging someone – because their hooked sting remains anchored to the penetrated skin and tears off killing the insect – wasps can sting over and over again, causing violent allergic reactions, up to anaphylactic shock, in people sensitive to histamine.

The newborn nest

In the spring, you can see even a single wasp going from inside to outside the house. You can assume, at this time of year, that it is a young queen who is building her nest or has just laid her eggs and carries food or is looking for building material. At this stage, if you can seal the entry hole when the wasp has flown away, you’ll be able to kill the larvae that will run out of food. The queen, on the other hand, will look for another place to make a new nest. Never close the nest if the wasp is inside, it’s completely useless as the insect will dig an escape route through the walls.

Remove the wasp nest

To remove the wasp nest it is always advisable to call an expert, especially if the nest is large and contains many insects. However, if you have to do it yourself, then some tips will come in handy. First of all, never close the entrance to the wasp nest: wasps have strong jaws and will look for another exit. In addition, these insects can become very aggressive if they feel threatened and attack repeatedly. The aggressiveness of wasps increases at the end of summer, when food is scarce. The wasp will die naturally with the arrival of winter. If you discover a wasp nest this season you can get rid of it easily because it is probably empty. During the summer and late spring you’ll have to use a good pesticide instead. After wearing protective clothing and covering all parts of your body well, read the instructions for the pesticide you have purchased carefully. Usually these are powder compositions that are placed at the entrance of the nest when it is empty: wasps will take it on their legs and wings when they cross it. To remove the nest you will need to make sure that all movement is stopped.

The best way to get rid of a wasp nest

Whenever you discover a wasp nest, the best thing is always to rely on an experienced professional and avoid dangerous do-it-yourself with improvised methods. Methods such as water, fire, sticks can have disastrous consequences for the environment and people. A trained exterminator, on the other hand, has access to personal protective equipment and is always protected against insect bites, but also against falling and inhaling harmful substances. The exterminator is qualified to work in small spaces or in air spaces such as attics, balconies and terraces. This gives him the opportunity to eliminate wasp nests in complete safety. Professional exterminators know wasps well, they know everything about their behaviour, their habits and how to prevent the establishment of further colonies. Qualified personnel are trained and authorised to use various pesticides, even those that are not available to the general public. These products are stronger than those sold freely on the market and are much more effective. Once the wasps are eliminated, removing the nest will be quick and easy. The site will have to be thoroughly cleaned, so next year you will avoid finding a new nest in the same place.
