I am watching the playoff game being played in Dallas right now and the players are sweating from the balmy weather. I believe you will not get the sustained low temperatures necessary to kill carpet beetles in your area unless an extreme, extended cold snap grips north Texas in the next few months (not impossible, but very doubtful), and you may end up inviting something worse to enter! Concerted, integrated pest control efforts are called for, since it is certain that by this time adult beetles are reproducing throughout the property. If the historic house cannot afford professional treatment, they might be able to apply for an emergency grant from the appropriate authorities. Failing that, there are some inexpensive pyrethrin bombs designed for residential use that might be used effectively in such cases. If the instructions are followed and appropriate preparations are made, this should help mitigate the problem with no damage or residual toxins. It would, at least, be better than nothing. Of course, good housekeeping measures should also be applied.
