Chemicals used to prevent Termites

Termites cause many millions of dollars of damage around the world each year. In Australia they cause more damage than all the floods, fires and storms each year. The termite control industry is constantly creating innovative solutions and seeking ways to find new and better ways of controlling and eradicating termites. There are a number of different chemicals used to prevent or eradicate termites.

Imidacloprid is made by Bayer and marketed as Premise. The active ingredient is Chloro-Nicotinyl, which is an insect nerve inhibitor. It is rated as practically non-toxic both orally and dermally for humans. According to scientists at Bayer, once applied imidacloprid lasts for at least two years and will still be 90% effective after 5-6 years. Bayer states that Imidacloprid works as an indirect colony control by killing termites without repelling them.

Bifenthrin is made by F.M.C. and is markted as Biflex Aqua. It is a synthetic pyrethroid water based termiticide. It is rated as slightly toxic if orally ingested and practically non-toxic if contact is made dermally. F.M.C. state that Bifenthrin will last for at least 10 years if it has been applied at maximum concentration. Industry experts recommend that it is reapplied every 5 years to ensure that it has not been degraded by water. Bifenthrin is able to bind well with soil making it a good choice when there may be a lot of moisture.

Fipronil is made by BASF and marketed as Termidore. Its active ingredient is Benzisothiazolin and it is rated as orally harmful if swallowed and it may irritate the skin if contact is made. Benzisothiazolin should last for up to 5 years before reapplication is required. It has been shown to be very effective for termite colony control and in preventing termites from entering buildings.
