Eliminating rats, mice, and other rodents can be accomplished using bait blocks and bait stations. Here is a step-by-step method for using these tools:

1. Identify the areas where rodents are present: Check for droppings, gnaw marks, and tracks. Common areas include kitchen cabinets, pantries, and basements.

2. Choose the right bait: Bait blocks and bait stations come in different formulations. Choose a bait that is appropriate for the type of rodent you are dealing with.

3. Place bait stations: Bait stations are designed to protect bait blocks from weather and non-target animals. Place the bait stations in areas where you have seen rodent activity.

4. Load bait into the bait stations: Follow the instructions on the bait block packaging to load the blocks into the bait stations. Be careful to handle the bait blocks with gloves to avoid leaving your scent on them.

5. Check bait stations regularly: Check the bait stations every few days to see if the bait has been taken. If it has, replenish the bait as necessary.

6. Remove dead rodents: Check the bait stations regularly for dead rodents. Wear gloves and dispose of dead rodents in a sealed bag.

7. Continue using bait until activity stops: Keep using bait until you no longer see signs of rodent activity. This may take several weeks, depending on the severity of the infestation.

8. Prevent future infestations: Once you have eliminated the rodents, take steps to prevent future infestations, such as sealing entry points and keeping food stored in rodent-proof containers.
