What Are Examples of Insecticides?

Some examples of insecticides include pyrethroids for chewing insects, residual insecticides for crawling insects and systemic pesticides for chewing and sucking insects. Read the label on pesticide containers to determine their appropriate usage.

The appropriate pesticide to use depends on the pest. For insects that crawl and chew on leaves and stems, pPyrethroids such as Spectracide and Conquest are ideal. These insecticides come in granular and spray form.

Residual insecticides leave a film on the surface of the plant onto which they are applied. Garden Tech Sevin, Malathion and MaxForce ant baits leave a residue that kills crawling insects including slugs, snails and ants.

Systemic pesticides are taken up by plants through the roots, into the stems and leaves of plants. When insects chew or suck any part of the plant, they ingest insecticide. Some examples of systemic pesticides are Orthene, Bayer Advanced Garden Rose Insect Killer Granules and Spectracide Systemic Tree and Shrub Insect Control + Fertilizer.

Insecticides with lower toxic effects are also available. Contact insecticides, including horticultural oils and soaps, kill pests when directly sprayed onto them. Some insecticides in this category include neem oil and Safer soap.

Plant-derived products can be used in the garden for less toxic effects. Pyrethrins are derived from chrysanthemum flowers and are toxic to fleas, ants and mosquitoes as well as other crawling and flying insects. Pyrethrins can be found in commercial products including Raid Flying Insect Killer and Schultz Insect Spray.
