Contact Poisons are pesticides that

Explanation:
Contact poisons work by killing pests through direct contact with the chemical. They don’t rely on the plant taking up the toxin or the pest needing to swallow it. The key idea is that the pest has to touch or encounter the treated surface for the poison to work, which is why these products are used by spraying or applying to surfaces the pest will contact. If you apply them properly, the insect itself must come into contact with the pesticide to be affected. This distinguishes them from systemic options, which rely on plant uptake, or from formulations that depend on ingestion or leaf absorption.
