Why do chemical treatments often fail?
Frequently asked questions
Why do chemical treatments against bedbugs often fail?
Failure is mainly due to genetic resistance. Modern bedbugs have developed a tolerance to conventional insecticides (pyrethroids). What's more, these products don't kill the eggs, allowing the infestation to restart a few days after the technician's visit.
What is the difference in efficiency between chemical and thermal treatment?
Chemical treatment often requires 2 to 4 passes to eliminate new hatchlings, with a success rate of 60 to 70 %. Thermal treatment (heat at 55°C) eradicates 95 to 98 % of pests, including eggs, in a single pass.
What are the preparation mistakes that keep bedbugs coming back?
The return of pests is often caused by a lack of rigor: laundry not washed at 60°C, excessive clutter offering hiding places, or forgetting to treat adjacent rooms. If a single refuge area is ignored, the colony quickly reconstitutes itself.
How long does it take bedbugs to die after treatment?
With a chemical protocol, total elimination takes 2 to 4 weeks (time needed to treat hatching cycles). With a professional heat treatment, bedbugs and their eggs die instantly as soon as the target temperature is reached.
How do I know if I've got rid of bedbugs for good?
An infestation is considered complete after a period of 6 to 8 weeks with no visible bites, droppings or moults. The installation of interceptor traps under the foot of the bed is recommended to confirm total eradication.
Why is it risky to treat bedbugs yourself?
Homemade solutions (vinegar, essential oils) simply disperse the insects into neighboring walls or apartments. Without professional equipment to reach eggs and deep nooks and crannies, you run the risk of selecting the most resistant individuals and making the situation worse.
