Identify the areas
First of all, it is important to confirm whether the rat is still there in the garage or not. It might have gone out so you need to make sure that the work you are doing is worth it. Identify the areas where the rat has been hiding for most of the time. This can be determined by following trails of food droppings throughout your garage. The rats generally hide in areas where there is no traffic.
Select a method to trap the rat
There are various methods to trap a rat which include the snap trap, electronic trap and a glue trap. The most commonly used one is the snap trap which has a loaded spring that catches the rat once it comes for the cheese. These traps are easy to place and have been very successful in recent times.
Bait the trap with cheese
You need to bait the trap with something that the rat likes so that it comes to get it and is caught. The bait may include cheese, bacon or dry fruit. Cheese is generally a very good option as it has a unique smell which the rats and mice love.
Carefully place the trap to catch the rat
The placement of the trap is the most important thing. You need to place the trap close to the area where you are sure that the rat is hiding. This would provide you with a great chance of catching it and is less time.
