Buying Guide

Before you purchase rat bait, there are a few considerations to keep in mind. Use our short buying guide below to help you select the right rat bait to match your needs.

Type of Bait

First, you should check for which types of rats/rodents the bait will kill. Some products are not effective on all rats, so you'll want to make sure the product you pick will work for your infestation.


Next, consider the quantity of bait. Some rat baits are sold in large tubs and can help homes with a large infestation or individuals who have a large piece of property and need to place bait around their home. Other products may come in a smaller quantity and can be a better option if you have a smaller home.

Indoor or Outdoor Use

Whether you plan on using the bait indoors or outdoors is another factor to consider. Check the packaging and confirm that the bait you're looking at will work in the area you need it for.

Included Bait Stations

Finally, consider whether any bait stations are included with the bait. If you are planning on using the bait in your home and have pets or small children, it is highly advised to use a bait station. Many bait stations are designed to be child- and dog-resistant. With these models you can be less worried about your child or pet accessing the bait, while still ensuring the rats are able to get to it.

Always Keep Safety in Mind

If you're using rat bait, it is essential to do so safely. Rat bait is a poison and can kill adults, children, and other pets. When working with rat bait, always use gloves and keep your hands away from your face. Once you have finished setting out the bait, thoroughly clean your hands to ensure all the poison is removed.

If you plan to use rat bait indoors, using a bait station can keep the poison out of the reach of children and pets. This is extremely important since tasting the bait could kill a child, dog, or cat.

Another important note is that if you find a dead rat in your home, you should be very careful removing it. Wear glove and put the rat into a trash bag. Tightly seal the bag and place it in a trash bin outside of your home.

After getting rid of rats in your home, disinfect any areas they may have come into contact with. Rats carry diseases which can spread to people or pets through their feces, urine, or saliva.
