Best rat poison options for your home and farm


If you are anything like me there is only one kind of acceptable rat — a dead one. While I understand the importance of every critter in the ecosystem, I would rather not see a rat around the house or the farm (although they do tend to love life out in the fields, around the barns, and stowed away in the machinery). Every year during wheat harvest, I tend to get a bit nervous about critters looking for a new home. In order to get a jump start on this year’s preventive actions, I have explored the best rat poison options.

As a third-generation farm family, you learn a few tips and tricks to keep the rats at bay around the shop. For example, it is always a good idea to keep a good barn cat or two. Not too many as that is overwhelming, but a good one to keep the mice and rats to a minimum. Having a hungry owl nearby also seems to help keep the balance. But even with a good barn predator, rats still find a way to wreck things — either by chewing into feed or seed bags or gnawing on wires, usually at the most inconvenient times.

A little added help keeping the rats in check is welcome, and we’ve tried a lot of solutions to keep those critters at bay.

Below are our five favorites when trying to nail down the best rat poison options. And all of this can be ordered online and, depending on the supplier, shipped directly to your house or to a local farm store. Take a peek for yourself:

Can rat poison kill people?

Simple answer is: Yes. Even if the reality of some ingredients is “only” a maybe, it’s always best to assume that a poison like this can be lethal to humans as well as rodents. According to the Centers for Disease Control and Prevention, many rat poisons on the market use strychnine as an active ingredient. Strychnine poisoning can cause extremely serious adverse health effects in people, including death. Other rat-poison ingredients, such as bromethalin, make severe reactions or even death virtually inevitable if consumed in sufficient quantities by humans. As with anything, the dose makes the poison, so it’s best to avoid ingesting such products or touching sensitive areas like your eyes.

Can rat poison be sent through the mail?

Various shipping companies, including the U.S. Postal Service, UPS, and FedEx, have unique requirements of what can be sent through their service. While it is possible to have a variety rat poisons shipped to you, a lot of depends on whether the retailer wants to send that kind of product through a delivery service and whether the delivery service allows it.

How quickly does rat poison work?

Elimination of rats won’t be instantaneous. Most good rat poisons on the market will take two to three days to start being noticeably effective, killing rats or forcing them elsewhere. Many poisons may also need up to a week or 10 days to take full effect. Exact timeframes depend on the scale of the infestation, both in terms of the number of rats and the size of the area you’re trying to target.
