After treatment — Fleas
No product kills fleas inside their cocoon. It's your vacuum, run daily, that triggers hatching and finishes the job.
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 until surfaces are completely dry, then ventilate before bringing pets back in.
24–48 h
Adult fleas eliminated
Very rapid drop in adult fleas present at the time of treatment. Bites decrease noticeably.
1–3 weeks
Cocoons hatching
Cocoons, impermeable to insecticides, hatch progressively. Young fleas die on contact with the residual product. Vacuum daily.
3–6 weeks
End of the cycle
No more hatching: the cycle is broken and the infestation is over.
What to do in the first 48 hours
- 1
Ventilate for 30 minutes on your return, once surfaces are dry.
- 2
Resume vacuuming the next day, then every day: vibrations trigger cocoons to hatch inside the treated zone.
- 3
Dispose of the vacuum bag (or empty the canister) outside, in a sealed bag, after every session.
- 4
Continue your pets' flea treatment according to your veterinarian's schedule.
What you must not do
- Do not wash treated floors or shampoo carpets for at least 14 days: you would remove the residual product.
- Do not stop the pet's flea treatment — it is the leading cause of reinfestation.
- Do not panic at seeing fleas: it's the normal cocoon cycle, not a treatment failure.
- Do not add an insect bomb (fogger): it does not penetrate carpet fibres.
😌This is normal
- Seeing fleas for up to 2 to 3 weeks after treatment.
- Fleas jumping mostly in the treated areas — that's where they contact the product and die.
- A few residual bites during the first week.
📞Call us back if…
- Fleas still numerous after 4 weeks.
- Bites getting worse or multiplying instead of decreasing.
- A pet scratching intensely despite up-to-date veterinary treatment.
- A sudden return after a flea-free period (outdoor source or untreated animal).
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 up veterinary flea treatment year-round, not just in summer.
- Vacuum regularly, especially in your pet's resting areas.
- Wash pet bedding every two weeks in hot water.
- Maintain the lawn and shaded areas of the yard where your pet lies down.
