Pyrethrum (Also known as Pyrethrin) is a natural, organic compound that is used as a fast-acting and effective insecticide. This plant-based material is popular for home use because it is generally considered to be very safe to use around people and are also environmentally safe.

In pest control circles, pyrethrin is known as a natural killer. It is toxic to most common insects, and kills quickly. It is a said to be an effective “flushing agent” to drive out hidden pests, making it a popular choice for battling cockroaches. It is used in a variety of pest-killing products, including sprays, gels, aerosols and fogging sprays. Solutions Pest & Lawn has several pyrethrin-based products, most of which are very affordable. Learn more about this product, how it works and shop for our pyrethrin-based products exclusively on this page.

What Is Pyrethrum?

Pyrethrin is a natural insecticide which derives from the extracted oils and petals of chrysanthemum flowers. Flowers of the chrysanthemum are taken and then dried and ground into powder or the oils are turned into what is known as pyrethrin. The formulation of pyrethrin consists of six chemicals that are toxic to insects.

Some of the more common insects that succumb to the effects of pyrethrin include but are not limited to mosquitoes, fleas, flies, moths, ants, spiders among others. Pyrethrin was registered for use in pesticides by the EPA in the 1950 but it had been used long before that to treat various pests. It is believed that pyrethrins were used as a natural form of pest control for thousands of years, possibly going back as far as 1000 BC when the Chinese discovered that crushing chrysanthemum plants and using the powder formed from it could kill insects.

While pyrethrins are an effective and natural pest control chemical, they are not potent for long periods of time because they typically contain impurities from the flower. Pyrethrins have since been modeled for its killing power by man who has created a synthetic version of the chemical called pyrethroids which produce a longer-lasting residual effect when applied to kill insects.

How Pyrethrin Works

The mode of action of pyrethrin is that it is a natural contact poison which affects the nervous system of the targeted insect. Pyrethrins overstimulates the nervous system of insects either touch it or ingest it. This overstimulation effect quickly leads to paralysis and the insect being unable to function normally. However, pyrethrin on its own does not necessarily mean that the insect will die. Over time, the natural pyrethrins are soon detoxified by enzymes in the insect. So some insects can recover and go back to normal functioning.

This is why in insecticides, pyrethrins are usually mixed with a supplementary chemical called a synergist to increase its effect so it does lead to insect death. For example, pyrethrin may be mixed with a synergist such as piperonyl butoxide (PBO). PBO will give the pyrethrin an added "kick" to increase its killing power.

Features of Pyrethrin Based Products

  • Fast Acting – Pyrethrin poisons insects upon contact, attacking the central nervous system and resulting in quick knockdown and kill.

  • Low Toxicity – Pyrethrin is one of the least toxic pesticides you can find on the market, and has a great track record for being environmentally-friendly and safe to humans and animals.

  • Repellent – In small doses, Pyrethrin serves as a repellent to protect food establishments, grain storage, and crops from insect pests.

  • Flushing Agent– Pyrethrin applied in insect hiding spots will irritate them and flush them out of hiding so they can be further exposed to the insecticide.

  • Versatile – Pyrethrin consists of a multitude of compounds rather than a single compound. This results more versatility and multi-use against pests that other insecticides can’t do.  It can be applied to target any pest in the house or garden.

  • No Insect Immunity – Insect resistance is not a problem because of the complexity of the molecule that pyrethrum is composed of.

Is Pyrethrin Safe To Use?

Pyrethrin is one of the safest pesticide chemicals on the pest control market. When applied according to label directions, pyrethrin is safe to use and apply in and around the home. Pyrethrin compounds can break down quickly in the environment, so pets and children can roam freely wherever the product is applied after it dries. However it is not a totally harmless chemical. Exposure to the skin or inhalation of the chemical Inhaling high levels of pyrethrum may bring about asthmatic breathing, sneezing, nasal stuffiness, headache, nausea, incoordination, tremors, convulsions, facial flushing and swelling, and burning and itching sensations
