A concentrated soap and water solution was poured directly into the nest entrance at dusk. The soap disrupts the waxy coating on the wasps' exoskeleton, causing suffocation. This treatment uses no synthetic pesticides — only biodegradable soap.

For nests concealed in wall voids or structural cavities, a desiccating silica aerogel dust was applied into the nest area. This natural mineral dust abrades the insects' protective coating, causing dehydration. No synthetic chemicals are used.

Exposed nests were physically removed after treatment. Entry points were sealed with caulk, copper mesh, or foam to prevent recolonization. Wall void entries will be sealed once all wasp activity has ceased (typically 3–7 days).

You should see a significant drop in wasp activity within 24–48 hours of treatment. Some returning foragers may fly near the old nest site for 1–2 days — this is normal and they will disperse.

Once sealed, the original nest site cannot be reused. However, new queens may attempt to build new nests in other locations next spring. Annual spring inspection is the best long-term prevention.

If the nest was inside a wall, do not panic if you see occasional wasps indoors for a few days. They are disoriented and dying. If significant numbers of live wasps appear inside the home, contact us immediately for retreatment.
