MetaLarv S-PT is a biorational pre-hatch insecticide for control of mosquito larvae in floodwater areas. It features the active ingredient (S)-methoprene — a juvenile hormone analog of mosquitoes that prevents the emergence of adult mosquitoes.

Suggested Rate Range:

2.5–10 lbs/acre (2.8–11.2 kg/ha)

Use lower application rates when water is shallow, vegetation and/or pollution are minimal, and mosquito populations are low. Use higher rates when water is deep (>2 ft/0.61 m), vegetation, pollution, and/or organic debris or water flow are high, and mosquito populations are high. Application of MetaLarv S-PT to sites subject to high organic pollution and water flow or exchange will diminish the product’s effectiveness.
