Make homemade rat poison by combining borax with chicken broth or peanut butter and leaving it around the house in areas where rats have been seen. Wear rubber gloves while working with borax, because it is poisonous to humans. Do not place borax where children or pets may try to play with it or eat it, as it is dangerous to consume.
- Gather materials
To make homemade rat poison, you need rubber gloves, borax and some food that is attractive to rats. Try chicken broth or peanut butter as a start. If these are unappealing to the local rats, experiment with mixing borax with other types of food till you find one the rats choose to eat.
- Create balls of homemade rat poison
Wear rubber gloves while working with borax, and do not touch your hands to your mouth. Mix borax with the chicken broth or peanut butter until you achieve a dough-like consistency. Roll the borax-and-food combination into small balls. If the rats don't eat the balls, try mixing the borax with dry ingredients such as chocolate milk mix.
- Place the balls in areas frequented by rats
Place the borax balls around the house in areas where you've spotted rats. Pay attention to make sure they're being eaten. Search for the dead rats and remove them promptly.
