On-site nitrogen bubble: eradicate without a drop of poison
Physical technique that lowers oxygen below 0.1% for 21-28 days inside an airtight bubble built around the object. Total lethality on eggs, larvae, pupae and adults. Zero chemical residues, fully reversible, usable in inhabited spaces.
"The nitrogen bubble can wrap entire rooms, trusses or large furniture — no disassembly, no chemistry."
What it is
Sealed bubble in multilayer barrier film filled with humid nitrogen (RH 50-65%) produced on-site by PSA generator. O₂ drops below 0.1% and is kept stable for 21-28 days at room temperature.
Furniture advantage: no crack risk from thermal shocks (unlike heat treatment). Whole-room advantage: no need to empty the house.

Who needs it
Antique and premium furniture, musical instruments (violins, pianos), panel paintings, gilded frames, vestments, rare books, private archives.
Also ideal for: entire trusses (sealing the under-roof cell), museum rooms during technical closure, premium B&Bs awaiting tourist season.
Our approach
Phase 1 – Bubble construction in barrier film, heat-sealed, anchored with specific tapes.
Phase 2 – Nitrogen filling from on-site PSA generator. Drop from 21% to 0.1% O₂ in 24-48 hours.
Phase 3 – Hold for 21-28 days. T°, RH, O₂ dataloggers monitored 24/7 remotely.
Phase 4 – Controlled opening. Parameter graphs delivered to client.
Documentation: technical report, treatment certificate, 5-year warranty on efficacy.
