MetaLarv XRP Mosquito Growth Regulator is a biorational, extended release pouch for pre-hatch & standing water control of mosquito larvae in catch basins & drainage systems. It features 4.25% (S)-methoprene — a juvenile hormone analog of mosquitoes that prevents the emergence of adult mosquitoes and utilizes Valent BioSciences’ proprietary Triple Release Technology™.
Utilizing Valent BioSciences’ Triple Release Technology, MetaLarv XRP provides an initial flash of (S)-methoprene for immediate control of mosquitoes — and the rate of flash is not dependent on water temperature. The second release occurs in standing water and unlike briquet formulations, initial floating of XRP ensures product does not immediately get propelled into catch basin sludge upon application. The third release ensures multiple point-source coverage for consistent control, providing public health professionals on average 90 – 100 days of residual control in catch basins under typical environmental conditions.
