For a long time people have used boric acid to kill rats. It is a white powdery substance that is relatively easy to find and buy. Many people believe that boric acid is an effective way to kill rats because it is a poison. However there is no scientific evidence to support this claim. In fact there is no scientific evidence to suggest that boric acid is effective against any kind of pest.
Boric acid works by dehydrating rats and causing them to die of thirst. However it is very difficult to ensure that rats will eat enough boric acid to kill them. In most cases rats will avoid eating boric acid because it is bitter and unpalatable. Even if they do eat it it is unlikely that they will eat enough to kill them. The LD50 (the amount of a substance that is deadly to 50% of the rats that eat it) of boric acid is 2.4 grams per kilogram of body weight. This means that a rat would need to eat about 24 grams of boric acid to have a 50% chance of dying.
There are many other methods of killing rats that are more effective than boric acid. Rat poisons are readily available and are much more likely to kill rats than boric acid. If you want to kill rats your best bet is to use a rat poison.
