Just like all spiders, the species that live in our homes have eight legs. Their bodies are divided in two parts: the cephalothorax (the head and thorax together) and the abdomen. They never have wings. Their shapes, sizes, and colours vary.

Development and Behaviours

Female spiders usually lay their eggs in a bag woven with silk threads. They deposit the bag in a sheltered place or keep it with them. They hibernate, no matter what stage they are at in their life cycle. The eggs usually hatch a few weeks after they are laid. The young who hatch already look like adults. They do not undergo metamorphosis but will molt a few times before reaching their adult size. While most spiders come from the outside, a few species tend to make their home inside our homes. They feed on insects that they hunt or that they capture in their webs. They also have silk-producing organs that spin webs used to build nests, capture prey or build cocoons that protect the eggs. Spiders may have up to eight eyes, but, interestingly enough, most of them are myopic. Most spiders are nocturnal and timid, and they prefer fleeing to confrontation.


It is recommended that you limit evening exterior lighting a minimum, and that you keep light away from doors and windows, both before and after treatment. Light attracts insects which, in turn, attract spiders.


  • Using a broom or vacuum cleaner, frequently clean baseboard heaters and corners of rooms to eliminate any food debris.
  • Outside, yellow electric lights don’t attract as many insects and, consequently, not as many spiders near the house.
