StrychnineStrycchine chemical compound

Strychnine is a main active ingredient used in various rodenticide bait products to treat for rodents. Strychnine is actually so potent that it can also get rid of larger pests like gophers.

Solutions Pest & Lawn is proud to carry products containing this powerful active ingredient. On this page, you can learn more about strychnine and why it works so effectively to kill even the toughest rodent and gopher infestations as well as shop the strychnine contained products we have in our inventory.

What is Strychnine?

Strychnine (Chemical Name: C21H22N2O2)  is a lethal natural substance that is used for the control of rodents and wild animals. Strychnine is used primarily as a pesticide, particularly to kill rats. Because strychnine is highly toxic and can be rapidly absorbed through the mucous membranes of the mouth, stomach, and small intestines, it is a restricted use rodenticide which only certified pest control professionals can purchase and use. 

In it’s original form,strychnine is a white, odorless, bitter crystalline powder that can be taken by mouth, inhaled (breathed in), or mixed in a solution and given intravenously (injected directly into a vein).

Strychnine was first registered as a pesticide to the EPA in 1947. However, strychnine had been used in the U.S. to control vertebrate animals for many years before 1947. The primary natural source of strychnine is the plant Strychnos nux-vomica which is found in southern Asia (India, Sri Lanka, and East Indies) and Australia.

How Does Strychnine Work?

Strychnine is a powerfully lethal poison which works via preventing the proper operation of the chemical that controls nerve signals to the muscles. When it comes to rodents, strychnine ramps up the reflex irritability of the spinal cord, which in turn causes a loss of normal inhibition of the body’s motor cells in the rodent, causing severe contractions of the muscles. One typical symptom of strychnine poison is an arching of the back.

Strychnine rapidly enters the blood, whether taken orally or by injection, and symptoms of poisoning usually appear within 20 minutes. The symptoms begin with cramps and soon grow into an erratic and agonizing convulsion that subside after a minute but recur at a touch, a noise, or some other minor stimulus. The respiratory muscles are also affected, leading to respiratory failure and death.

How is Strychnine Used?

Strychnine is currently registered for use only below-ground as a bait application to control pocket gophers. The end-use products are formulated as a grain-based bait or a paste.


Baiting can be done manually, or with the use of application equipment. Typical application equipment includes a burrow-builder, which digs artificial tunnels; or an impinger, which "injects" bait into the animal's tunnel.


Is Strychnine Safe To Use?

The EPA places strychnine in Toxicity Category I, indicating the greatest degree of acute toxicity. Since most strychnine based baits are placed below ground to control gophers and rodents, the person most at risk of exposure is the handler of the pest control product.It is highly recommended to wear personal protective equipment required to lessen the risks of inhaling, ingesting or coming in contact with the skin. The minimum PPE suggested when handling strychnine based products includes chemical resistant gloves, eye protection, and dust masks.
