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?

Is the house sealed up? Throw a couple of those bug bombs in there and leave

Wrap the beams in visqueen or then painters plastic and put a insect bomb inside it. Leave covered for a couple days and that should kill the nest in the beams.

Also why hang the beams before Sheetrock? I did this in previous house and the seasonal changes caused gaps between Sheetrock and beams. This resulted in Sheetrock powder on my beams along with gaps every time the wood would shrink/swell. Our new house we hung Sheetrock then the beams and have had zero issues being the Sheetrock is under the beams.

I'd get a pump sprayer and hit them with insecticide.

They'll be looking for water and I doubt they'll give you much of a problem.
