Can I DIY this?
Pro RequiredThis is not a DIY job.
Because of the safety risk, property damage, or specialized equipment involved, this pest should be handled by a licensed professional. We'd rather tell you that straight than sell you a product that won't fix it.

- Confirm activity — Formosan termites build mud tubes like other subterranean termites but can also construct above-ground "carton" nests, and colonies grow large fast.
- Because of how aggressive and fast-spreading this species is, we'd strongly recommend a professional inspection before attempting DIY treatment — misjudging the colony size here can mean expensive repairs later.
- If proceeding, treat accessible galleries directly and apply a full exterior soil barrier treatment per label instructions.
- Give it the full 90 days non-repellent products need to work through the colony before judging results.
- Monitor closely — check monthly for new mud tubes or frass, since this species can rebuild activity faster than other termites.
Wear long pants, a long-sleeved shirt, closed-toe shoes with socks, chemical-resistant gloves, and goggles. Add a respirator if the label calls for it or ventilation is poor.
