Repellent and Non-repellent termiticides

Termiticides are pesticides used for termites control. Basically there are two groups of termiticides that differentiated by how termites are affected when they encounter treated soil.

Repellent termiticides do not kill termites, because insects are able to detect the treated soil and do not tunnel into it.Termiticide is injected into areas of the soil around a home's foundation, preventing termites from entering into the structure. The slab is drilled and the soil is treated underneath. Trenches are dug around the foundation outside and within crawl spaces and filled with termiticide, creating a chemical barrier which the termites will not be able to pass. The termiticide repels the termites by blocking them off from their food source. Ideally the termites are turned away from the structure and the entire nest will be killed.

Non-repellent termiticides also known as a delayed termiticide treatment, this method of non-repellent termite treatment works much more slowly than a repellant treatment. The structure is drilled, trenched and injected as with the repellent liquid, but the termiticide is not repellent to the termites. The termites cannot detect the non-repellent termiticide in the soil so they tunnel into it and are killed. One advantage of this is that it can be transmitted to other members of the termite infestation with a single dose. This method is often used in conjunction with bait stations

Some insecticides used as repellent termiticides are:

Bifenthrin, Cypermethrin, Fenvalerate, Permethrin

All synthetic pyrethroids chemicals classified as "Repellent Termiticides"

Some insecticides used as non-repellents are:

Chloronicotinyls, Chlorophenapyr, Fipronil, Imidicloprid, and Phenylpyrazols.

Both repellent and non-repellent termiticides have proven satisfactory for making effective barriers when applied properly.
