After treatment — Bed Bugs
Treatment doesn't end when the technician leaves. What you do over the next 3 weeks largely determines success.
What happens, day by day
Understanding the timeline avoids needless worry — and tells you when something is genuinely wrong.
0–6 h
Returning home
Wait out the re-entry delay, then ventilate for 30 minutes with windows open before settling back in.
24–72 h
First effects
You will see dead bed bugs. Residual activity is normal: some emerge from hiding on contact with the product.
1–2 weeks
Eggs hatching
Unreached eggs hatch. Young bugs contact the residual product and die — which is why you must not clean.
2–3 weeks
Follow-up
A follow-up inspection checks whether any activity remains. The barrier is still active at this stage: bugs that hatched since the intervention encounter it in turn, which resolves most files in a single intervention. If activity persists, we come back at no charge under the written guarantee.
4–6 weeks
Elimination confirmed
No new bites and no fresh traces on bedding: the infestation is under control.
What to do in the first 48 hours
- 1
Ventilate the home for 30 minutes on your return, windows open.
- 2
Wash only food-contact surfaces (counters, table) — never baseboards or the area around the bed.
- 3
Put back clean bedding washed at 60 °C and install certified bed bug encasements on the mattress and box spring.
- 4
Keep sleeping in your usual bed: your presence draws remaining bugs toward the treated areas.
What you must not do
- Do not wash, scrub or mop baseboards and treated areas for at least 14 days.
- Do not switch bedrooms or sleep on the couch: you would move the infestation to an untreated room.
- Do not apply any store-bought insecticide over the professional treatment.
- Don't skip the follow-up inspection: it confirms elimination and closes the file.
😌This is normal
- Seeing a few bed bugs, alive or dead, for 1 to 2 weeks.
- Possible new bites during the first 7 to 10 days.
- A faint product odour for 24 to 48 hours.
📞Call us back if…
- New and numerous bites after 3 weeks.
- Live, active bed bugs after the follow-up inspection.
- Fresh black spotting on sheets beyond 3 weeks.
- Bed bugs appearing in a room previously unaffected.
Your written guarantee covers a free return visit during the covered period.
Preventing a return
A successful treatment eliminates the current infestation. These habits prevent the next one.
- Keep the encasements in place for at least 12 months.
- When travelling: inspect the mattress and headboard, keep luggage elevated, wash everything on return.
- Thoroughly inspect any second-hand furniture or mattress before bringing it home.
- In a building, report any suspicion to the manager quickly for coordinated treatment.
