Lambda Cyhalothrin 10% WP Insecticide Uses

Lambda Cyhalothrin 10% WP is a synthetic pyrethroid insecticide, registered for use in India under the Insecticides Act, 1968, formulated as a wettable powder (WP). Unlike the field-crop insecticides on this site, it is registered specifically for public-health and household pest control — mosquitoes, houseflies and cockroaches — applied as an indoor residual spray rather than a crop spray. This page lists its mode of action, key benefits and the recommended application rate as per the Central Insecticides Board & Registration Committee’s (CIB&RC) official list of approved insecticide uses.

Mode of Action

Lambda cyhalothrin acts on the insect’s nervous system as a fast-acting contact poison. It binds to voltage-gated sodium channels in nerve cell membranes, keeping them open longer than normal; this causes repeated, uncontrolled nerve impulses, leading to tremors, paralysis (knockdown) and death of the target insect. Applied as an indoor residual spray on walls and resting surfaces, it leaves a residue that continues to knock down mosquitoes, houseflies and cockroaches that come into contact with the treated surface for some time after application.

Features & Benefits

• Fast knockdown action gives quick, visible control of mosquitoes, houseflies and cockroaches on contact.
• Residual indoor-surface application continues to control pests landing on treated walls and surfaces after spraying.
• Registered specifically for public-health and household use, distinct from agricultural field-crop applications.
• Wettable powder (WP) formulation is straightforward to mix with water for indoor spraying.

Recommended Usage of Lambda Cyhalothrin 10% WP Insecticide

The table below gives the CIB&RC-recommended application rate exactly as published in the Central Insecticides Board & Registration Committee’s (CIB&RC) list of approved insecticide uses (Government of India). This is a public-health/household indoor residual spray, measured per 500 m³ of floor area, not a per-acre crop-spray rate — see the note below the table for details.

The rates above are shown exactly as published in the CIB&RC’s list of approved insecticide uses (Government of India) for public-health and household indoor use, measured per 500 m³ of floor area — this is not an agricultural field-crop dose, so no hectare-to-acre conversion applies. Always confirm the current dose on your specific product’s label before use.

How to Use

1. Confirm the correct application rate for your target pest (mosquitoes, or houseflies/cockroaches for household use) and the floor area to be treated, from the table above.
2. Mix the required quantity of Lambda Cyhalothrin 10% WP into 10 litres of water per 500 m³ of floor area, stirring to form a uniform suspension, since this is a wettable powder (WP) formulation.
3. Apply as an indoor residual spray to walls, ceilings and other resting surfaces where the target pests land, using a suitable hand-compression or knapsack sprayer fitted with a flat-fan nozzle.
4. Ensure the room is vacated during spraying and ventilated well afterward before re-occupation, and cover or remove food, utensils and drinking water before treatment.
5. Avoid spraying directly onto food-preparation surfaces, and keep children and pets away from freshly treated surfaces until they are dry.

Precautions & Safety

• Wear appropriate PPE — mask/respirator, gloves and goggles — while mixing and spraying, and avoid inhaling spray mist.
• Follow the recommended dose strictly; do not exceed the stated concentration per 500 m³ floor area, and do not apply to food, utensils or drinking-water containers.
• Vacate and ventilate the treated room as directed on the label before re-occupation, and keep children and pets away from freshly sprayed surfaces until dry.
• Spray only on the surfaces specified on the label (walls, resting surfaces); do not spray directly onto skin, clothing or open food.
• Store in the original, tightly closed container in a cool, dry place away from direct sunlight, food and feed, and out of reach of children and pets.
• Wash hands, face and any exposed skin thoroughly with soap and water after handling or spraying, and change out of contaminated clothing before eating, drinking or smoking.
