Before seeing how to exterminate wasp nests, a little biology wouldn't hurt.

It should be noted that wasps are flying insects identifiable by the yellow and black bands adorning their abdomen. Sometimes the bands are white in color. Also known as "yellow jackets" or "hornets", these insects range in size from 10 to 25mm, or 0.39 to 1 inch. In comparison with the bee, the wasp is less hairy. Notice, also, that wasps have two pairs of wings, one was smaller than the other. They also have three pairs of legs. It should be noted that in the queen, the abdomen of the wasp ends with a spawn. While, for worker wasps, there is a sting.

Finally, wasp species can be classified into two categories. On the one hand, there are solitary wasps that rarely build nests. These species generally live alone and are not really dangerous.

On the other hand, there are social wasps that gather in swarms and build nests. They then live in colonies, are more common but also more harmful by their behavior. The nests they erect are in the shape of paper and of various sizes. Luckily, some of their nests are very visible. Others, on the other hand, are quite hidden.

In Quebec, you will find, on average, four types of wasps: mason wasps, social wasps, gall wasps and yellow jacket wasps (very large).

You will notice their presence, usually, through their buzzing sounds and their honeycombed nests.

Just like the society of bees, that of wasps is very well organized. Each individual fulfills a well-defined function in the swarm. These social insects live in colonies. The latter (colonies) are composed of a few future queens, worker wasps and males (at a certain time of the year).

During the winter period, the elements of the colony die. Only the queens will survive which will hibernate until the spring period to build new colonies. Mated queens rarely opt for an old nest. They will decide to build a new one often at tree level, near a property or even in the foundation of your house. In the latter case, they become harmful to you. Indeed, if they are disturbed, they will not hesitate to bite you in order to defend their new territory.  

Depending on the location and climate, the shapes of wasp nests will diverge significantly. Indeed, you can find paper nests in attics or trees. Conversely, you may notice nests under your tunnels. In Quebec, note that there are three types of wasp nests that you may encounter. First, there are the parasol-shaped nests. Small in size (275 individuals maximum), this type of nest can take place anywhere in the house. Then there are the nests that look like cones. Larger in size, this type of nest can easily reach the size of a balloon. These nests are most often in the forest.

The extermination of wasp nests from the house is both risky and complicated. Indeed, the colonies will certainly defend the nest by attacking you. And, as announced earlier, their bites can be deadly if you don't treat it in time.

To prevent wasps from often taking up residence in your home, you must observe certain preventive measures.. So, to guard against a wasp infestation, you act as follows. First, it is advisable to cover all your foods rich in protein and sugar. Then, when you eat outdoors, avoid eating sweet foods with strong odors without covering them.

If you have ever noticed a wasp nest in your home, it is not recommended to use perfume or hair spray near them.

Finally, it is recommended not to walk barefoot on the garden lawn in winter. At the end of the summer, the wasps are very numerous and active.

In order to exterminate wasp colonies from the house, you have several options. Among these is the use of traps or chemical products.

Another solution is to use chemicals against wasps. In this case, an insecticide should be sprayed near the wasps' nest. For your safety, it is advisable to do this at night (wasps are less active at night). Also, it will be necessary to remain calm if the wasps are agitated.

So, with these tips, you should be able to get rid of wasp nests. But, again for your safety, let a professional exterminator take care of it, ask us for a free estimate.
