A
Premise pre-construction termite treatment begins working as soon as termites contact the treated soil, but its effectiveness is designed to be preventative rather than reactive. Because Premise is applied before the slab is poured, termites typically never establish an infestation in the first place. If termites attempt to tunnel through the treated soil, they are affected within hours, with death occurring over the following 1–3 days. Premise uses imidacloprid, a non-repellent, systemic active ingredient, meaning termites cannot detect the treated zone. As they move through the soil, they unknowingly absorb the insecticide and spread it to other termites through contact and grooming. This stops colony development before termites can reach the structure, providing long-term structural protection rather than visible “after-the-fact” control. When applied correctly during pre-construction, Premise can provide years of termite prevention, as long as the treated soil barrier remains undisturbed.
