Altosid® XR Extended Residual Briquets

Habitats that need the most control are often the most undesirable and difficult to treat. So you'll be pleased to learn that a single application of Altosid® XR Extended Residual Briquets (Altosid® XR Briquets) offers up to 150 days of control. Like Altosid® 30-Day Briquets, XR Briquets require no expensive application equipment, and can be used for pre-treatment before the wet season. That means you're better able to treat hard-to-access or outlying areas, and can eliminate the additional costs associated with travel and multiple re-treatments. Altosid® XR Briquets are available in the original “cork” shape, as well as a “slim” size shape for even the tightest fits. Altosid® XR Briquets make application easier and still deliver season-long control of mosquito larvae for up to 150 days.
