Rats can threaten homeowners by contaminating food supplies, damaging property, and spreading diseases. These pests multiply rapidly, so a small infestation can quickly become a major problem. While rat poison can be a helpful tool for controlling rat populations, it's crucial to use it safely and responsibly. Always follow label instructions and keep rat poison out of reach of children and pets. For severe infestations or to help ensure safe and effective eradication, it’s always best to consult a rodent control professional first.

What is rat poison made of?

Rat poison, also known as rodenticide, is designed to kill rodents like rats and mice. It typically contains chemicals that interfere with the rodent's bodily functions. Once a rat ingests the poison, it enters their digestive system. Depending on the type of poison, it can cause internal bleeding, organ failure, or other fatal consequences. The exact effects and the time it takes for the poison to work vary depending on the chemical used. Ultimately, the rat will be affected by the poison and die, often in a hidden location within the home or building where it was exposed.

Rat poison vs. bait

Rat poison and rat bait help control rat populations and are the same thing. Rat poison, also known as rat bait, is a toxic substance that kills rats when they eat it and usually contains anticoagulants or other chemicals that harm the body’s functions. People typically use poison in places with high rat populations, like commercial buildings, warehouses, and food processing plants.

Are rodenticides effective for a rat infestation?

While rodenticides can effectively reduce rat populations, they are often insufficient on their own to fully eliminate a rat problem. Rodents can develop resistance to certain types of rodenticides over time, making them less effective. Rodenticides can only target rats in direct contact with the poison, leaving other rats unaffected.

Does rat poison get rid of rats long-term?

While rat poison can effectively eliminate a rodent infestation in the short term, it may not provide a long-term solution. Rats can resist certain types of poison, and new generations can quickly repopulate an area. To help ensure safety, always follow the label instructions and store rat poison in secure, child- and pet-proof locations.
