There are a few things to consider before treating a slab for termites. The first is to accurately measured and scale the slab. Once this is known, the proper treatment options can be selected. When it comes to treating a slab, there are three main options: baiting, fumigation, or sealing. Baiting systems use food or attractants to lure the termites out of their nests, then a chemical is applied to kill them. Fumigation uses poisonous gas to kill the termites all at once. Sealing systems involve coating the slab with a layer of waterproof material and applying pressure. This creates a barrier that stop pests from entering and prevents water damage. All of these treatments require some preparation ahead of time.
