Bed bugs die from water loss — not poison.
VA88 attacks a physical structure, not a nerve. That changes everything: no known resistance, no re-entry interval, no neurochemical residue. Here's the cascade, step by step.
Five stages from spray to long-term protection.
- 01
The spray hits the bug
Plant oils make contact with the bed bug's outer wax layer — the barrier that normally holds its water in.
- 02
The wax barrier dissolves
The oils break down that wax layer, so the bug's water-retention system fails. No nerve is involved — so there's nothing for the bug to build resistance to.
- 03
The breathing pores seal
Botanical oils seal the pores along the bug's body, adding respiratory stress on top of the water loss.
- 04
The bug dries out — fatally
Water exits faster than the bug can replace it. The dehydration is physical, irreversible, and complete — usually within minutes to hours.
- 05
Residulen protects for up to 12 months
The dried Residulen layer bonds to surfaces — mattress seams, baseboards, carpet edges — as an encapsulated reservoir of the soy-protein active. Any bug that crosses it later, including newly hatched nymphs, releases the active and meets the same fate, for up to a year.
Conventional pesticide vs. mechanical kill.
EPA 25(b) means the active ingredients are on the EPA's Minimum Risk list — they don't require registration as pesticides because they pose negligible risk to people, pets, or the environment.
