Hazard Substance, Low Toxicity.
7.5% Beta-cyfluthrin SC offers pest control in the environments of
hotel, hospital, school, store, warehouse, livestock, poultry, etc.
The control spectrum includes mosquitoes,flies, cockroaches and
other hygiene pests.
With a new generation containing fluoration and active ingredient
of lambda-cyhalothrin, which is recommended by WHO, Weide 2.5%
lambda-cyhalothrin SC is high insecticidal efficient, fast knock
down and long term effect. The product offers satisfied toxicity
against resistant pests and mites. It could reach better effect
when rotating with other insecticides.
