MetaLarv XRP – Don’t Get Stuck in the Muck!
A new approach has been developed for the extended control of mosquito larvae in catch basins & drainage systems! Are potential vectors of disease breeding in your stormwater? Are your bricks getting stuck in the muck?
Azelis A&ES and Valent BioSciences are Here to Help!
Problem: A product is needed that provides multiple point sources in a catch basin for consistent residual control.
Solution: 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 Triple Release Technology™ for Up To 105 days of Control
- Initial flash of (S)-methoprene provides immediate control with no dependency on water temperature
- Second release of the “micro-briquets” allows for control of multiple broods
- Third release ensures control in situations of dry-down in the catch basin and re-flood
