MetaLarv S-PT Controls for up to 42 Days

MetaLarv S-PT is a field-proven (S)-methoprene pellet used to control floodwater mosquitoes for up to 42 days, the longest residual-control pellet on the market. It can also be applied for pre-flood control up to 28 days before a flooding event. In difficult-to-predict flood locations (irrigation fields, pastures, etc.), MetaLarv S-PT is the most advanced option as it can remain effective after flood/dry-down/re-flood events. This is due to the Triple Release Technology, which provides extended release of (S)-methoprene despite challenging weather conditions.

Field Tested Pre-Flood Applications

EI of Aedes vexans after pre-flood ground applications (4 lbs/acre) to floodplains in Minnesota

EI of Aedes vexans after 20 and 41 days pre-flood application (5 lbs/acre) to flood/dry-down/re-flood microcosms in Washington

Clean Formulation

MetaLarv S-PT

MetaLarv™ S-PT was designed to improve (S)-methoprene product handling. MetaLarv’s Triple Release Technology utilizes a non-charcoal UV protectant that eliminates much of the particulate and respirable dust produced by standard (S)-methoprene pellets and sand-based products. This technology substantially reduces worker exposure to dust and keeps equipment cleaner.

VectoPrime FG Reduces Operational Costs

VectoPrime FG is a biological larvicide containing 400 ITUs of Bacillus thuringiensis israelensis strain AM65-52 and 0.10% (S)-methoprene and provides complete single-brood control. Each microparticle of VectoPrime FG contains both active ingredients in a specific ratio for consistency in application and results. This product can also be applied up to 14 days pre-flood, which reduces the need to monitor flooding or wait for expected hatching. The double potency of VectoPrime FG allows for significantly lower application rates (approximately 50% reduction), thus reducing operational costs.
