Now, there’s always a chance that some of these rats will not eat the onions and die out, so you may have to try something else.

Snap Traps
Snap traps have been around for a while and are often very cost-effective. Putting these snap traps in locations, you suspect the rats may be hiding is a good idea.
A piece of advice here is to use rat bait. Often in movies, a piece of cheese is used as rat bait. However, I’ve seen that peanut butter performs the best.
Now, I know some people reading this article may not have peanut butter, so in that case, bacon, fruits, and cereal also work very well.
