What is Boric Acid?

Boric acid is a white crystalline powder that is derived from boron. It is commonly used in pesticides, antiseptics, and even in some medicines. Boric acid is also used as a household cleaner and for treating fungal infections. It is a natural substance that is safe for humans and pets in small doses.

How Does Boric Acid Kill Rats?

When rats consume boric acid, it acts as a stomach poison. It disrupts the rat’s digestive system and causes dehydration. Boric acid is also abrasive, which damages the rat’s digestive tract. Rats cannot excrete boric acid, and so it accumulates in their bodies, leading to their death.

How to Use Boric Acid to Kill Rats?

To use boric acid to kill rats, follow these simple steps:

Step 1: Find Rat Infestation Areas

Identify the areas where rats are most active. Look for droppings, gnawed objects, and urine stains. These areas are where you should focus your treatment.

Step 2: Prepare the Boric Acid Mixture

Mix boric acid with sugar or peanut butter in a 1:1 ratio. Rats are attracted to sweet or fatty foods, so this mixture will attract them. Wear gloves when handling boric acid to avoid any skin irritation.

Step 3: Place the Mixture in Rat Infestation Areas

Place the boric acid mixture in the rat infestation areas. Use a spoon or disposable gloves to avoid touching the mixture. Rats will consume the mixture and eventually die.

Step 4: Clean Up After Treatment

After the treatment, clean up any remaining boric acid mixture. Dispose of any dead rats in sealed plastic bags and place them in the trash.
