Step 1
How to recognise the infestation?
When spiders settle in for good, webs reappear within a few days of every cleanup — in ceiling corners, behind furniture, in cellars, garages, attics and around window frames. You spot small whitish egg cocoons stuck in the crevices, regularly encounter specimens in several rooms, and at night notice quick movements along the baseboards. Such a marked presence almost always reflects an abundant pantry nearby — midges, mosquitoes, flies or moths drawn in by outdoor lighting.
Step 2
Why is it dangerous?
Most spiders in the Île-de-France region are harmless, but their multiplication causes daily anxiety, especially for arachnophobes or when children share the affected rooms. A few species can bite when trapped in clothing or a sheet, sometimes with marked skin reactions in sensitive people. Above all, an established colony signals another hidden infestation of flying or crawling insects that must be treated in parallel for a lasting result.

Step 3
Our intervention method
- 1
Inspection of entry points
Locating webs, cocoons and transit zones (cellars, attics, window frames, garages).
- 2
Prior mechanical dust removal
Web and cocoon removal with HEPA vacuum to optimise treatment adhesion.
- 3
Residual peri-building spraying
Application of a micro-encapsulated insecticide on thresholds, frames and facades: 3–6 month barrier effect.
- 4
Prey treatment
Simultaneous elimination of flying insects (midges, mosquitoes) that attract and feed spiders.
