Bonide Mosquito Beater WSP
09/17/25
Bonide Mosquito Beater WSP, manufactured by Bonide, is a water-soluble insecticide package that selectively controls mosquito larvae and developing mosquitos before they hatch and become breeding adults in standing water.
This microbial insecticide comes in the form of a water-soluble package that dissolves readily in water to release granules coated with active ingredient Bti 1.7%. This active ingredient works to destroy the cellular lining of the insects digestive tract.
Bonide Mosquito Beater WSP is a fast-acting selective insecticide that can be used in stagnant, polluted, or algae-covered water without harming fish, amphibians, or other beneficial aquatic organisms.
Tools Needed
It comes ready to use, but you will need the appropriate personal protective equipment (PPE) such as gloves when handling this product.
How to Use
- Step 1: Determine how much Bonide Mosquito Beater WSP to use by calculating the square footage of the standing water surface. You will need to measure the length and width of the water site in feet and multiply them together (length X width = square footage). For clear water containing little algae use 1 pouch of Bonide Mosquito Beater WSP per 50 sq. ft. of water surface or 2 pouches per 100 sq. ft. Heavy infestations applications in clear water use 2 pouches of product per 50 sq. ft. or 3 pouches per 100 sq. ft. For polluted water with light infestation apply 2 pouches of product per 50 sq. ft. or 3 pouches per 100 sq. ft. Polluted water with heavy infestations will use 3 pouches of product per 50 sq. ft. or 4 pouches per 100 sq. ft.
- Step 2: Drop the appropriate amount of Bonide Mosquito Beater WSP while still in its packaging into the water.
- Step 3: Once applied, the package should dissolve within several minutes. Retreat as needed every 7 to 14 days to control mosquito populations.
