Carpenter Ants

We are currently building a new home and starting to hang Sheetrock. I supplied some old cypress beams and timbers that had been stored outside under cover for about a year. We brought the beams and timber to the new house to store inside and get the beams hung before the sheetrock was installed.

After the beams were in the house, we noticed they were full of carpenter ants which appear to have spread through the house. I did some research on how to exterminate the ants and it was recommended to use a non-repellant insecticide to prevent them from spreading further. Before reading that I purchased a quart of Talstar Professional Insecticide which appears to be a repellent insecticide.

I also reached out to a local pest control company to get a recommendation and price on getting rid of them.

Any recommendations on DIY (repellant, non-repellant, or other solution) or should I just let the pest control company handle it?
