Contact insecticides are chemical products that are destructive, harmful, or deadly to a specific insect once they are absorbed via contact.
These pesticides may be inorganic, organic, or just natural insecticides that leave a poisonous residue behind.
Contact Insecticide Types
Popular products incorporate mostly Aerosols and Foggers. They can be distinguished through toxicological activity, method of infiltration, and chemistry.
Some of the main contact insecticides are;
- Acephate (Orthene)
- Carbaryl (Sevin)
- Fipronil
- Pyrethrins
- Pyrethroids
- Bifenthrin
- Cyfluthrin
- Cypermethrin
- Deltamethrin
- Lambda-cyhalothrin
- Permethrin
- Es-fenvalerate
- Tefluthrin / tralomethrin
- Liquid fipronil/spinosad
The natural Pyrethrins ingredient eliminates an ant within minutes. Carbaryl and Acephate may take a couple of days (more or less) while the Granular fipronil takes a month or more to wipe out colonies. Whereas heated water, D-limonene treatments, and Pyrethrins possess very little durability.
Carbaryl and Acephate dissolve fast while the Pyrethroids can persevere for several weeks to months. Fipronil does last, as it could persist for months, even up to a year.
Spray using a contact insecticide that has a lasting residual activity are; fipronil, permethrin, lambda-cyhalothrin, cypermethrin, or bifenthrin.

LIST: Examples Of Systemic Insecticides
Sometimes, these contact insecticides can be toxic to other mammals, stimulating allergic reactions like breathing problems, asthma, skin irritation, etc. on humans.
They may also cause chronic poisoning for individuals who come in contact with them. More so, the runoff of the insecticide contaminates underground water sources and poses a danger to animals around.
Anyone applying a contact insecticide must be ready to follow the users’ guidelines to avoid contamination of any type.
