Liquid termiticides are usually applied completely around and underneath a structure covering all areas where termites might gain access. For new construction, this is accomplished by treating the graded soil and foundation walls before the slab is poured. For an existing building, the perimeter of the foundation is trenched and drilled, then treated with termiticide. The goal of the treatment is to put a chemical blanket between the termites in the soil and the structure above. The chemical blanket can also affect those termites inside a building by preventing their successful return to the soil. In many cases, these termites will die of dehydration.
At the time of this writing there are a few non-repellent termiticide treatments available on the commercial market. These chemicals are not repellant and termites cannot detect them in the soil. Therefore, the termites tunnel into the termiticide while foraging, contact the chemical, and die.
Premise (Bayer Corporation, Kansas City, Mo.) contains the active ingredient imidocloprid. Imidocloprid is unique because it not only kills termites that contact a lethal dose, but it also kills them at doses too small to cause immediate death. If a termite contacts even a very small amount of imidocloprid it will become lethargic and forget to eat and feed other termites. It will also forget to groom itself so it soon becomes infested with soil fungi. The termite eventually dies as a result of these indirect symptoms of imidocloprid exposure. A disadvantage to Premise liquid termiticide is that it is somewhat more expensive than the pyrethroid termiticides. Note: Premise is also available in a foam aerosol formulation. The foam is used for spot treatments, where it is injected directly into termite galleries in the infested wood.
Termidor (BASF Corporation, Research Triangle Park, N.C.) is also a non-repellent termiticide. The active ingredient is fipronil. Fipronil is unique in that it can be transferred from one termite to another through contact and trophallaxis (communal feeding). This allows it to affect more termites than those that contact the chemical directly. The advantage of this product is its long-term effectiveness in the soil. Test data indicate that fipronil may be effective longer after the initial application than other liquid termiticide products. A disadvantage is that Termidor is more expensive than other liquid termiticides.
Phantom (BASF Corporation, Research Triangle Park, N.C.) is another non-repellent termiticide. The active ingredient in Phantom is chlorfenapyr. Chlorfenapyr is an insecticide that is not toxic to the insect until it is broken down by enzymes in the insect’s immune system. Once broken down, the toxic metabolites of chlorfenapyr stop the insect cells from producing energy. The termites die because they cannot produce the energy needed to function. Because of its mode of action, termites contacting Phantom do not die immediately but live long enough to carry some of the termiticide away in their gut and on their bodies. These termites live long enough to transfer (through contact and trophallaxis) some of the termiticide to their nest mates. This transfer produces secondary kill within the colony. Like the other non-repellent termiticides, Phantom is also more expensive than the pyrethroid formulations.

As defined by the state of Florida, a Wood Destroying Organism (WDO) Report is “a written report of an inspection on a home for visible and accessible evidence of an infestation or damage by wood destroying organisms”.
- A WDO report may also be commonly called a “Termite Inspection”, “Clearance Letter”, or “Termite Letter”.
- A WDO inspection not only checks for subterranean termites and dry wood termites, but will also include wood destroying beetles and wood decaying fungi.
- Carpenter ants and carpenter bees are NOT reportable as a wood destroying organism on the state of Florida WDO form.
- By Florida statute, a WDO report is provided when a home or other structure is being sold and the mortgage lender OR buyer requests the WDO inspection as part of the transaction. If an inspection is done for these purposes, the inspection must be reported on a specific report form as required by Florida Law (Chapter 482.226, Florida Statutes and Chapter 5E-14.142(2)(c), Florida Administrative Code).

Subterranean termite treatment has changed dramatically over the last two decades. The number of systems, application techniques and products available for termite control has tripled in the last 10 years. Today, if you experience a subterranean termite swarm, you may call four different pest management companies and receive four completely different treatment recommendations. In most cases the Pest Management Professional (PMP) is only familiar with the treatment used by his or her company. So how can you make an informed decision? This fact sheet gives an overview of all the currently available subterranean termite treatment methods. It includes general descriptions of treatment products, brand names, application techniques, and their unique features.
- There are two general categories of termite treatment, liquids and baits. Soil-applied liquid termiticides have been around for decades. Their purpose is to provide a long-lasting chemical barrier that excludes termites in the ground from entering buildings. In most cases, termites in the structure die off as well, since they cannot return to the soil. Most former products wererepellentrather than lethal to termites foraging in the soil. Newer materials, such as Premise® (imidacloprid), Termidor® (fipronil), and Phantom® (chlorfenapyr), are non-repellent and termites tunneling into the treatment zone are killed. Overall the non-repellent products are proving to be more reliable in their ability to resolve termite problems in the first attempt. All registered termiticides (both repellent and non-repellent) can be effective, however, and homeowners should not base their purchasing decision on product alone.
Termite prevention is key to avoiding costly structural repairs and replacement costs. Most structures in Florida are treated against termite infestations during the initial construction process. These preventive termite treatments are commonly referred to as pretreatments or “pretreats.”
A pretreat is intended to create a uniform barrier of termiticide between termites in the soil and the wooden components of the building. To ensure a uniform barrier, termiticide labels prescribe the volume, concentration, and locations for the application of the termiticide. This means relatively large volumes of termiticide solution are needed to adequately treat the soil in and around the foundation walls, support piers, and soil areas to be covered with concrete (slab areas).
