There are a few things you can do to control rat pests:

1. Identify the entry points. Rats can squeeze through very small openings, so it's important to seal up any cracks or holes in your home's foundation, exterior walls, and roof.

2. Remove food sources. Rats are attracted to food, so it's important to keep your home free of crumbs and other food particles. Store food in airtight containers, and clean up spills immediately.

3. Set traps. There are a variety of rat traps available, both live and kill traps. Choose the type of trap that is best for you and your situation.

4. Use rodenticides. Rodenticides are poisons that can kill rats. However, they should be used with caution, as they can also be harmful to pets and children

Here are some additional tips for rat pest control:

• Keep your lawn and landscaping trimmed and free of debris. Rats like to hide in these areas.

• Inspect your home regularly for signs of rats, such as droppings, urine, or gnaw marks.

• If you see a rat, don't panic. Just shoo it away and take steps to prevent it from coming back.

With a little effort, you can keep rats out of your home and enjoy a rat-free environment.
