The ground is sinking around my slab and I need to add soil you can see under slab a little bit. Can I add soil around slab treated with Termidor? Will this affect the barrier the pest control company dug a trench around my house and treated with Termidor? Do I have to retrench or can I just add soil treated in a wheelbarrow with Termidor?
Anytime you are adding soil on top of soil that was previously treated with Termidor SC, you need to be sure to also treat that new soil so it is still protected. We recommend applying the Termidor SC in a trench with the soil that is and will be directly up against the foundation of the treated structure. Please refer to the termite treatment article for full instructions on treatment
