ULTRATHOR provides fast elimination of the termites attacking your property together with highly effective, long-term residual termite control. With its unique mode of action we guarantee that ULTRATHOR will provide proven protection against termite entry for up to 8 years or more.
ULTRATHOR is non-repellent to termites. This means that they are totally unaware of its presence in the soil around your home. So they continue their normal foraging activities through the soil, totally unaware that it is slowly building up in their bodies, until it reaches a lethal dose. And no more termites! ULTRATHOR is toxic to termites by contact or ingestion. It causes death to termites by disrupting their nervous system. It binds to three types of calcium-channels on the membranes of insect neurons, preventing calcium ion influx into the cell. One of these channels is controlled by the neurotransmitter gamma-aminobutyric acid (GABA) and the other two are controlled by glutamate. The presence of three different target sites accounts for ULTRATHOR’s high potency against termites.
ULTRATHOR displays selective activity due, in part, to the fact that glutamate-mediated chloride channels are unique to invertebrates, like insects and termites. Also, fipronil binds more tightly to the GABA controlled chloride channel of insects than to that of mammals or birds. This increases the margin of safety for people, pets and other animals. Fipronil is also non-toxic to earthworms.
ULTRATHOR adsorbs tightly to soil, has low solubility in water, and a low vapor pressure; as do its environmental degrades. Low application rates, combined with the unique ULTRATHOR formulation also reduces the risk of run-off.
