What should I do if I have Rats?
The rat is the most intelligent rodent that lives around humans. If there is only one, you might be able to catch it. If there are several of them, you will need to get help.
Poisons should not be used in the house. The rat is too big to use poison with since there will be a strong and long-lasting decomposition smell. A rat is 10-15 times heavier than a mouse. It can take up to 1 month for a rat to decompose.
