A contact pesticide is a pesticide designed to exterminate pests directly upon contact. Extremely lethal to the target, contact pesticides can be natural, inorganic, or even organic products that often leave some kind of residue behind.
Most contact pesticides come in the form of aerosols or foggers. They are commonly used on a wide-scale on agricultural crops that produce higher yields than smaller-scale crops.
Contact pesticides can be dangerous for warm-blooded animals and humans. The majority of contact pesticides and insecticides contain methyl parathion, diazinon, malathion, parathion, carbamates as well as organic phosphates.
These substances are generally most effective when used against mites and aphids. Contact pesticides are generally manufactured to cause contact poisoning by entering the pest’s body through their epidermis, hence causing instant death. This differs from fumigation, whereby the pesticides are designed to enter the pest’s body through their respiratory system.
