Barriers and baits
Some projects use physical barriers or bait systems instead of or with soil treatment.
Certificates
Keep the treatment certificate. Buyers and lenders ask for it.
Coordination
Schedule the pest control company with the concrete crew so the pour is not delayed.
Disturbance
Digging after treatment can break the barrier. Retreat disturbed areas.
Additions
Porches and additions poured later need treatment too.
Getting started
Add termite pretreatment as a required step in your pre-pour checklist.
Common mistakes
Pouring before treatment, losing the certificate and forgetting later pours.
Example
A builder in the Southeast lost a closing date because the termite certificate could not be found. After that, the superintendent attached the certificate photo to the pre-pour checklist on every house.
Pre-pour checklist item
Grade complete, plumbing and electrical under slab installed, termite treatment applied, certificate received and photo attached, vapor barrier ready. No pour until every item is checked.
Communicating with buyers
Buyers and their inspectors often ask about termite protection. Having the certificate ready builds trust at closing.
