![]() ![]() In the case of using foams under a concrete slab, the reasoning is the same. ![]() Foam treatments may also be preferential because their less watery consistency means they are less likely to damage the physical aspect of wood or walls. These qualities allow the injected foam to work its way into the small nooks and crannies and fill up the space where liquid termiticide may be impractical. The preference for foam is due to its nature and ability to expand. These areas may include wall voids, door jambs, crawl spaces, and even under a concrete slab. On the other hand, foam termiticide is a preferred treatment method for termites in hard-to-reach areas. Their particular grooming habits cause the liquid termiticide to spread quickly and kill the queen. This fact is specifically valid in the case of subterranean termites. After injection, termites move through the termiticide-treated soil and use their grooming habits to kill the colony. The other termiticides are non-repellent these create zones where you want to have termite action. The termiticides used for these treatments can then do one of two things. They either create a barrier that stops the entry of termites altogether, or they can form a treated zone. The termiticides that deter termites are repellents they produce an invisible wall that keeps termites from crossing over the treated area. Injectors that use an anti-return system prevent backflow, thus protecting the applicator and keeping your product where you want it. Luckily, today’s treatment technologies offer a solution to this problem. ![]() When injecting liquid product, it may splash back through the drill hole and cause an unwanted mess on the job site. One common criticism of this method is the issue of backflow in concrete slab injections. You will often hear this technique referred to as trenching and rodding. This method may also require drilling and injecting termiticide into the concrete around the property. For subterranean termites, one of the most common liquid treatments involves injecting termiticide into the soil surrounding the home. If you are considering a liquid or foam treatment , keep in mind that there are different types on the market. ![]()
