About Us

Liphatech is a worldwide manufacturer and marketer of pest control products. Our state-of-the-art US facility was opened in Milwaukee, WI, in 1987. Worldwide, Liphatech commits substantial resources to the development of premier bait matrixes specifically designed to carry our active ingredients achieving superior acceptance and control of the target pests (rodents, slugs and snails) for which our products are marketed.

Liphatech, known as Lipha in the early days, began in 1946 in France as a pharmaceutical company. There, research focused on anticoagulants for the treatment of heart patients and resulted in the development of three active ingredients: 1) chlorophacinone, in the early 1960s, branded as Rozol, a multiple-feed rodenticide that began to replace warfarin as the rodent control product of choice. 2) bromadiolone, in the early 1970s, our first single feed rodenticide active ingredient was developed in the same fashion and 3) difethialone, developed in the late 1980s, is the newest single feed rodenticide active ingredient available.

Today, as a wholly owned subsidiary of DeSangosse, Agen, France, Liphatech also markets the world's leading slug and snail bait matrix under the Metarex brand name. This product, based on the metaldehyde active ingredient, has opened new and exciting market opportunities in specialty agricultural crops such as artichokes, citrus and grass seed production as well as in commercial nursery and ornamental production.

The most recent development by Liphatech is soft bait, the next evolution in rodenticide. As The Soft Bait Innovators™, Liphatech continues to bring the most technologically advanced rodenticides to market, in a soft bait formulation that’s easy to use, effective and highly palatable. We are always searching for new ways technology can help us assist pest management professionals and agricultural producers in their rodent control efforts.
