The proper preparation of your home before a bed bug treatment is crucial to ensure the effectiveness of the extermination. Poor preparation can reduce the efficiency of the treatment by 50% and prolong the infestation. This guide explains step-by-step how to maximize your chances of complete eradication from the very first intervention.
Why Proper Preparation Makes All the Difference
According to the Government of Quebec, inadequate preparation is one of the main causes of extermination treatment failures. Bed bugs are resilient insects that hide in the smallest cracks. If your home is not properly prepared, they can simply migrate to untreated areas, making the intervention ineffective and prolonging your ordeal by several weeks.
The good news? With methodical preparation and the right techniques, you can significantly increase the success rate of extermination and quickly regain peace of mind.
Essential Preparation Steps Before Treatment
1. Decluttering and Organizing Spaces
The first step is to reduce as much as possible the places where bed bugs can hide. Decluttering is not just an aesthetic task — it’s a tactical necessity.
Actions to take:
- Remove all items from under beds and storage areas
- Empty drawers from dressers and nightstands
- Move furniture at least 30 cm (12 in.) away from the walls to allow access to baseboards
- Store personal items in airtight, transparent containers
This step allows the exterminator to access all critical areas and apply the treatment evenly. Steam treatment services in particular require clear access to be fully effective. 
2. Treating Textiles and Clothing
Bed bugs love to hide in fabrics. The thermal treatment of textiles is a non-negotiable step.
Recommended protocol:
- Wash all clothing, sheets, curtains, and textiles in hot water (minimum 60°C / 140°F)
- Then dry them on the hottest cycle for at least 30 minutes
- Items that cannot be washed should be placed in airtight bags and treated by freezing or professional heat treatment
- Immediately seal clean textiles in watertight plastic bags
High-temperature thermal treatment is known to effectively kill bed bugs at all life stages, from eggs to adults. This is why washing in hot water followed by extended high-heat drying is essential.
3. Preparing Furniture and Surfaces
Every surface must be accessible and cleaned to maximize treatment penetration.
Specific preparation checklist:
- Vacuum mattresses, box springs, baseboards, and furniture thoroughly (discard the vacuum bag outside immediately)
- Disassemble bed frames if possible to expose all joints
- Remove mattress and cushion covers
- Steam-clean hard surfaces if possible
Warning: Never use store-bought insecticides before the arrival of the exterminator. These products can scatter bed bugs and create resistance to professional treatments, compromising the intervention. 
Costly Mistakes You Must Avoid
Mistake #1: Throwing Away Furniture Prematurely
Many people panic and discard furniture before professional treatment even begins. This is usually unnecessary and expensive. Qualified exterminators use thermal treatment and freezing methods that can save your belongings.
Mistake #2: Neglecting Adjacent Areas
Bed bugs do not stay confined to the bedroom. Partial preparation leaves hiding spots intact. Prepare all adjacent rooms, even if you haven’t seen bed bugs there.
Mistake #3: Using Store-Bought Products
Aerosol bombs and store-bought insecticides can do more harm than good. They scatter bed bugs to other areas and may make them resistant to professional treatments. This practice is also discouraged by the City of Quebec in its official guidelines.
Mistake #4: Not Communicating With Neighbors (Apartments)
In multi-unit buildings, bed bugs can travel between units. Inform your landlord and neighboring tenants. A coordinated approach is essential to prevent reinfestation.

Frequently Asked Questions
Ideally, start preparing 2-3 days before the treatment. This gives you enough time to wash and dry all textiles, declutter thoroughly, and vacuum deeply. Rushing preparation increases the risk of missing critical areas.
This depends on the type of treatment. Heat treatments generally require an 8-12 hour absence, while steam treatments often allow for a quicker return. Your exterminator will provide specific instructions based on the method used.
Electronics should be placed in airtight bags or treated separately. Consult your exterminator before treatment—some equipment requires freezing rather than heat treatment to prevent damage.
A new infestation is possible if new bed bugs are introduced (travel, used furniture, visitors). However, proper preparation combined with professional treatment eliminates the existing infestation with a success rate of over 90%. Preventive measures significantly reduce the risk of reintroduction.
Absolutely. Bed bugs move around and can hide in adjacent rooms even if you haven’t seen them there. Thoroughly treating all living areas greatly increases the effectiveness of the treatment and prevents the insects from migrating.
