What is chemical treatment against bed bugs?

Chemical treatment involves using specific insecticides to eradicate bed bugs. These products are formulated to target their nervous system, paralyzing and killing them rapidly. However, these products are not available to the general public. They are reserved for professionals registered as users of biocidal products in the restricted circuit, in accordance with Belgian regulations. This exclusivity guarantees safe handling and optimum application.

Chemical treatment is often preferred for its ability to reach inaccessible nooks and crannies and to offer prolonged action against bed bugs. However, to obtain satisfactory results, it is imperative to follow a rigorous protocol.

How does chemical treatment work?

The process begins with a thorough inspection of the premises by a professional. This step is crucial in locating areas of infestation, particularly in bedrooms and living rooms, where bedbugs hide in mattresses, box springs, cracks and crevices. Once the areas have been identified, application of the insecticide can begin.

First intervention

During the first visit, the professional applies insecticide to all identified areas. This step is designed to eliminate active bedbugs. However, the eggs, which are often resistant to insecticides, may remain. What's more, some bedbugs hide in hard-to-reach nooks and crannies, escaping the product during this first application.

Repeated interventions

For complete eradication, several treatments are required. Treatments are generally spaced 15 days apart, to allow time for eggs to hatch and new bugs to be exposed to the product. A cycle of 2 to 3 treatments is recommended to maximize effectiveness.

Product persistence

The products used have a remanence of around 15 days. This means they remain active on treated surfaces, eliminating any bedbugs that come into contact with them. To preserve this effectiveness, we advise you not to clean surfaces during this period.

Tools and techniques used

Professionals have several tools and techniques at their disposal to complement chemical treatment and achieve maximum efficiency.

Insecticide fumigant

The fumigant diffuses a fine smoke that penetrates every nook and cranny of the room. Ideal for treating large surfaces, it is an effective complement to spraying. However, smoke has no residual effect and does not act on eggs, making it a complementary solution.

Bug spray

This aerosol is designed for targeted application to mattresses, box springs and other textile surfaces. Thanks to its nozzle, it reaches hard-to-reach areas. Although less powerful than other methods, it is useful as a complement to the main treatment.

Anti-moth lacquer

Applied to areas of passage, the lacquer acts as a barrier to prevent bedbugs from re-nesting. It slows down their reproduction thanks to a growth regulator and offers a prolonged action over time.

Pre-operation preparation

Rigorous preparation is essential to ensure effective treatment. Here are the steps to follow:

1. Washing bedding : Run all infested sheets, covers and clothing at a temperature of at least 60°C to kill bedbugs and their eggs.
2. Dismantling furniture Remove bed frames, sockets, curtains and anything else likely to hide bedbugs.
3. Moving furniture Move furniture away from walls to facilitate technician access.

During the operation, you will have to leave the site for several hours to avoid any risk of exposure to chemicals.

Advantages and disadvantages of chemical treatment

Benefits

• Affordable cost : Chemical treatment is generally less costly than heat treatment.
• Long-lasting effectiveness : The products remain active for several weeks, gradually eliminating the remaining bedbugs.
• Accessibility : To treat hard-to-reach areas.

Disadvantages

• Egg resistance : Bedbug eggs are often insensitive to insecticides, requiring repeated interventions.
• Toxicity : The products can be harmful to humans and pets.
• Insect resistance : Some bedbugs develop resistance to chemicals, reducing their effectiveness.

Cost of chemical treatment against bed bugs

The cost of a chemical treatment varies according to several factors: the surface area to be treated, the number of infested rooms and the products used. Here is an estimate of rates in Belgium:

• Treating an infested room between €100 and €400 (inc. VAT) per run.
• Fumigation A basic fumigator can cost around €10 incl. VAT, while a professional model can cost up to €90 incl. VAT.

For a complete treatment, it is advisable to budget accordingly, including any additional interventions.

Conclusion

Chemical bedbug treatment remains an effective solution for eradicating these pests. With the help of qualified professionals, you can return to a healthy, peaceful home. Don't wait for the infestation to get worse: contact a specialized company for fast, safe treatment.
