Gentrol Point Source, from the Zoëcon Professional Products division of Central Life Sciences, is an effective addition to pest management professionals’ cockroach and stored product pest protocols. The active ingredient and insect growth regulator (IGR), (S)-hydroprene, translocates from treated areas to locations that are typically difficult to treat. Gentrol Point Source creates a protection zone of up to 75 square feet by preventing pest larvae and nymphs from progressing into adults, and sterilizing surviving adults. The easy-to-use product is activated by simply squeezing the raised end, making it ideal for confined areas where traditional baiting or spraying is difficult and competing food sources are present. Using an IGR such as Gentrol Point Source has been found to increase feeding activities and improve baiting programs, the company says.
