Liquid Chemical Barriers for subterranean termite control work by killing or repelling termites before they enter the structure. The termites are killed before they enter the structure and/or killed upon leaving the structure to return to their colony. In some cases, when using a repellent chemical such as Talstar Professional, the termites will avoid the chemical and stay away from it. If termites are present inside the structure and a repellent chemical is used, the termites will "back up" inside the walls to avoid it. In some cases they will attempt to organize a secondary colony to continue living inside the structure or they will attempt to find a new way out of the structure. This is very seldom successful for the "blind" subterranean termite workers. Usually, in the absence of moisture, they are simply trapped inside the wall, cannot organize a new colony and eventually dehydrate (dry up) and die. It is common in homes that have had chemical treatments performed to find thousands of dead termites in walls where the termites were trapped and could not get out and simply died due to lack of moisture.
Repellent termite insecticides tend to repel termites away from structures. Talstar Professional, Dragnet FT, Bifen and Prelude are examples of repellent chemicals. The repellency factor of these liquid termite chemicals have specific uses - primarily in preconstruction treatments (before the structure is built) and in areas where fast control of subterranean termites is desired.
Non-Repellent termite insecticides are chemicals designed to be transparent to subterranean termites. This non-repellency factor is a great attribute in subterranean termite control. "Imidachloprid" registered as Premise (United States) and Hachikusan (Japan), "Fipronyl" registered as Termidor and "Chlorfenapyr" registered as Phantom are examples of non-repellent chemicals. The termites are not repelled and in most cases cannot even sense that these chemicals are present. Non-repellent chemicals work best in spot treatment applications because the termites are killed instead of repelled to other non-treated areas of the structure.
A newer non-repellent and also "GREEN" termiticide is called "Altriset". Altriset is non-repellent to the termites and also very safe for the environment, probably the safest of all currently available termiticides. It works by paralyzing the muscles of the termites. The termites then then die due to lack of activity and inability to eat.
Termidor - (Fipronyl) is widely used for termite control and is the most popular termiticide in the USA. Termidor is the only Termiticide to show 100% effectiveness against termites and also provides termite colony elimination. It was first introduced in the United States in 2000. Since then, it has shown 100% control in over 90% of the test sites, and continues to provide excellent control. Fipronyl, the active ingredient, kill s termites and also has a transfer effect that is passed from worker termites to the colony. It is regarded as the most effective termite chemical available and used by almost all Pest Control companies. It is also regarded as one of the most toxic. Termidor has been banned in the European Union, France, Japan and other countries due to toxicity concerns. It is generally regarded as safe when properly applied.
In the 1970's, high pressured sprayers putting out a whopping "150 PSI" were popular in the pest control industry. The thought was that the higher the pressure, the better the spray coverage.
All of this changed in the early 1990's when it was found that lower PSI did a better job of dispersing chemicals with reduced "drift" and mess. Chemical manufacturers changed their labels (directions for use) to specify that very low pressure of around 25 PSI was to be used in liquid termiticide applications. Today, all pest control companies that are doing liquid temite chemical applications use smaller gas powered or electric powered sprayers. In fact, most of these sprayers deliver less pressure than a standard water hose!
For the Do It Yourselfer - to spot treat with termite insecticides, you don't need expensive equipment. In fact, most liquid termite chemicals can be applied with a few simple tools readily available from your local hardware store. Of course in more complex termite infestations, the services of a professional should be obtained. However, if you want to do it yourself, we've put together a simple strategy that makes the job easy.
Most termiticide labels have specific instructions on how to perform treatments along foundation areas.
Termiticide labels have specific instructions on how to perform treatments below cement or slab foundations.
Hammer Drill. You can rent hammer drills from any tool rental center. The standard drill bit is a carbide coated tip drill - standard size is 1/2" wide by 18" long. You may also want to rent a ground fault interrupter (GFI). The GFI is a small box that the drill plugs into. The GFI then plugs into any 110V wall plug. GFI's are especially useful when drilling inside slab foundations near plumbing lines. If the drill bit contacts any metal in the slab, it will cut off electricity to the drill and save the drill bit , not to mention plumbing lines, post tension cables, rebar, etc. Make sure that you test the GFI prior to use by touching the tip of the drill to any grounded metal object, such as water lines under a sink, etc..
Most termiticide labels have specific instructions on how to perform wall foaming. To foam a wall using a liquid Termiticide, the termiticide has to be mixed with a foaming agent to make it foam. It usually will not foam on its own. Mix the normal amount of termiticide and then add in 2-4 oz of foaming agent such as ProFoam Platinum Concentrate. The amount of foaming agent depends on the hardness of the water, so experiment to find that perfect ratio to get a shaving cream consistency foam. All foams have to be applied with a special foam applicator such as the Solo Wall Foamer.
After you have stopped the termites with a termiticide, it is time to go after the colony with a bait system. Termite Colony Baiting can be easily performed with our Hex Pro Termite Baiting System. Using a termite baiting system without first killing the localized termite infestation with a termite insecticide can allow the termites to continue feeding until control with the baits are achieved. Although some pest control companies follow this philosophy, and some pest companies use liquid termiticides without a termite bait system at all, we think the best approach is a combination of the two. This is currently the technique that most reputable pest control companies use.
