Insects and other arthropods

Unwanted roommates

English
The immature stage (1) and the adult stage (2) of the masked hunter are seen in houses because they have strayed there by accident, not because they are living there. This insect feeds on other arthropods, including earwigs. To rid your home of the masked hunter, simply release it outdoors or to kill it with some soapy water.

Among the millions of species of arthropods that live on the planet, very few of them are harmful to human beings. Out of those that are, many live exclusively in tropical zones.

In fact, these small creatures are very useful. However, when their activities conflict with ours, some people just want to be rid of them as quickly as possible. Their reactions may be even stronger when arthropods settle into their home or garden.

Better cohabitation

Insect invasions that are genuinely hazardous to human health are rare. However, the presence of insects or other arthropods on our territory is sometimes enough for us to declare war on them. One of the first reactions is to buy insecticide or, if the situation seems alarming, to call an exterminator. Before taking these measures, here are a few tips to help you deal with the situation:

  • Identify the insect or arthopod and learn about its lifestyle or get help from our experts by contacting our entomological information service.
  • Find the point of entry into your home. Once you’ve done this, you can take action: install or repair screens, fill any cracks, replace any pieces of rotten wood.
  • Find out what is making it possible for the arthropods to multiply. They need a hospitable living environment and a source of food to live. Without these two elements, they cannot reproduce.
  • If you decide to use insect repellents, choose the most environmentally friendly products, such as borax or diatomaceous earth. Borax affects the insect’s exoskeleton and causes it to die from dehydration.
