Is temephos an insecticide?

Yes, Temephos is a selective organophosphate insecticide that targets mosquito and midge larvae in water, stopping them from becoming disease-carrying adults.

How does temephos work?

Temephos inhibits acetylcholinesterase enzyme in insect larvae nervous systems, causing paralysis and death within hours while remaining safe for mammals and aquatic life at recommended doses.

How is temephos applied?

Temephos can be applied as granules, powders, or liquid concentrates directly to water surfaces. The dosage ranges from 1 to 10 ppm, depending on the mosquito species and water conditions.

How effective is temephos?

Temephos kills 90-100% of mosquito larvae within 24 to 48 hours. Its effects can last from 2 to 12 weeks, depending on the product, sunlight, and organic matter in the water.

Is Temephos safe for drinking water treatment?

Yes, the World Health Organization has approved Temephos for use in household water storage containers at concentrations up to 1 ppm, with no health risks.

Overview of Temephos

Temephos is an organophosphate larvicide used around the world to control mosquitoes and midges in public health and environmental programs. It comes as a white to pale yellow powder or as a liquid concentrate. While it is very effective against aquatic insect larvae, it has low toxicity for mammals.

Temephos kills mosquito larvae in water before they grow into biting adults, helping to prevent diseases such as malaria, dengue, and Zika. It is the main ingredient in products like Abate®, which health authorities use for safe and targeted mosquito control.

Applications of Temephos

Mosquito Larvicide & Vector Control

Temephos is added to water where mosquitoes breed to kill their larvae.

It controls Aedes, Anopheles, and Culex mosquitoes, which are known to spread major diseases.
It is used in places like drinking water storage, rice fields, and decorative ponds.
Essential for Agriculture Industry disease prevention.

Public Health & Disease Prevention

The World Health Organization recommends it for programs that control malaria, dengue, and chikungunya.
It is used in urban water containers, old tires, and catch basins.
Complements growth regulators like 1-Naphthaleneacetic Acid.

Midge & Blackfly Control

Temephos removes bothersome midges and blackfly larvae from rivers and reservoirs.

It helps lower the number of pests around crops.
Works with Diatomaceous Earth for integrated pest management.
Pairs with nutrient programs using Zinc Sulphate Anhydrous.

Aquaculture & Water Management

It helps control mosquito predators in fish ponds.
It is safe for use in aquaculture when applied at the recommended rates.
Supports 1,2-Dibromoethane fumigation programs.

Safety & Handling Guidelines

Always handle Temephos using standard safety precautions for pesticides.

Keep Temephos in its original container and store it in a cool, dry, and well-ventilated place, away from food and out of reach of children.
Wear protective gloves, goggles, long sleeves, and a respirator when mixing or applying Temephos.
Be careful not to let Temephos contaminate water sources outside the areas you are treating.
Wash yourself thoroughly after handling Temephos and change out of any clothing that may have been contaminated.
Check the Material Safety Data Sheet (MSDS) for detailed information on toxicity, first aid, and what to do in case of a spill.
