We are building a house that sits 20 feet from a lake in central Louisiana. I would like to know if there is anything I can do before we drywall to prevent insects and other pests in years to come. I have been told that I can sprinkle boric acid in the walls before the drywall goes up but haven't found much online to back that up and my husband wants something more to go on than heresy. I'd like to know what options there are and that they are safe for children and pets. Cockroaches and spiders (black widow/brown recluse) are a big problem in this area so they are my number one concern right now but I'm sure we will be greeted with tons of other creepy crawlies. Thanks in advance for any advice!
