Suggested Rate Range:

(Excluding catch basins, storm drains, etc.) 0.5–1.5 lbs/acre (0.6–1.7 kg/ha)

Use higher rates (1.0–1.5 lbs/acre; 1.1–1.7 kg/ha) in areas where extended residual control is necessary, or in habitats having deep water or dense surface cover. Apply uniformly by conventional ground or aerial spray equipment. Reapply as needed every 1–4 weeks.

Liquid sprays have been demonstrated to work extremely well to treat Culex spp. habitats in “closed” habitats such as catch basins. For your specific catch basin needs, please contact our technical development specialists for further information.
