Therefore, this guide will help you fulfill the Merchant Request, More Pest Control in Resident Evil 4 Remake.

Key Takeaways

  • Pest Control is a series of three Merchant Requests in different Resident Evil 4 Remake chapters.
  • You aim to exterminate Rats for the Merchant and earn your reward through 3 Spinels.
  • The first Pest Control request takes place in Chapter 2. Here you are required to kill 3 Rats located within the Abandoned Factory.

  • Moreover, Even More Pest Control is the third and final Merchant Request about killing Rats in Resident Evil 4 Remake. This request comes in Chapter 14 and will take you around the Waste Disposal area hunting for 4 Rats.
  • Although, in other animal-related Merchant Requests, you need to bring back the animals to Merchant. It would be best to exterminate the rats to earn your reward.

For those uninitiated, Pest Control is a series of Merchant Requests presented to the players early in the game. Like most Merchant Requests, your goal here is to kill animals for the Merchant. Some requests will require you to kill vipers, while some may take you out on the lake to capture a Lunker Bass for the Merchant.

However, during Pest Control requests, players must hunt down rats for the Merchant. These Rats may not be as easy to spot due to their small size and fairly quick speed.

Moreover, the Merchant does not want Rats, so you do not need to store them in your inventory. He simply wants you to kill them to earn your reward, as he is also tired of these rodents filthy his place of business.

Pest Control – First One

The first Pest Control request, titled Pest Control, comes on very early in the game. This is your first interaction with the Merchant during Chapter 2. You will find a pamphlet next to his shop for your Merchant Request. The Merchant will require you to kill three rats inside the abandoned factory you just exited. So now you must go back inside and kill three Rats to earn your reward.

Possible Location: Abandoned Factory

Finding these Rats may seem like a tedious task, but it is simpler than that. You need to be aware of your surroundings and have a good set of headphones. It may be difficult to spot these small quick pests, although you may be able to hear them if they are nearby.

Moreover, they will make a distinct squeaky sound that you can hear easily. Therefore, when you hear the sound look at the ground, you will be able to spot the rats easily. 

You just have to find and kill three rats in the factory. All of these rats will be on the bottom floor, and as this is your first Pest Control, the rats are fairly easy to spot.

Once you have killed the three Rats by shooting or stabbing them with your knife, you can head back to the Merchant and be rewarded with 3 Spinels. You can use these Spinels to trade various items from the Merchant, ranging from Yellow Herbs to Stocks for your handguns.

More Pest Control – Second One

More Pest Control Request

As the name suggests, More Pest Control is the second time the Merchant wants you to exterminate Rats in Resident Evil 4 Remake. This request comes in Chapter 9 of the game during the castle section. You will find the pamphlet right at the end of the Grand Hall, on a wall next to the door.

The request pamphlet is right in front of the Headless Statue of a Lion, so you cannot miss the request. The Request is almost the same as Pest Control. Here you are required to kill 3 Rats inside the Grand Hall and Library area.

Possible Location: Grand Hall and Library

All three of these Rats can be found in three separate Locations. Therefore, you can find the first Rat in the room beside where you found the Request Pamphlet. Just head inside this small Red Room, and you will see the rat on the floor. Shoot or stab to exterminate the vermin. The Second Rat can be found in the hallway that leads to the Armory.

You would need to take the hallway that goes from the Grand Hall. If you are lucky enough, you will spot the Rat right as you enter the hallway that leads to the Armory.

The location of the third rat comes in a bit later during Chapter 10. You would need to unlock the Library Area to finally be able to kill the third rat. Just head inside the Library, which is located behind the Headless Statue.

Moreover, you must head deep inside the library to find your vermin running around. However, make sure you listen to the rat on your headphones as this room gets dark, and spotting the rat is difficult.

Similar to the first Pest Control, the Reward here is also spinels. Moreover, as you are not selling anything to the Merchant, you will not earn any Pesetas. This side quest does not require collecting rats; just killing them. So when you return to the Merchant, you will be rewarded with 3 Spinels. You can use these Spinels to trade for several items from the Merchant, including exclusive crafting recipes.

Even More Pest Control – Third One

Even More Pest Control Request

The third and final Pest Control Request, titled Even More Pest Control, comes in Chapter 14 of the game. You can find this request right next to the Merchant after you have saved Ashley from the Holding Cell within the Facility.

The Merchant will be located right at the entrance of the Cargo Depot. The goal is the same as the previous pest control request; however, now you must exterminate 4 Rats to earn your Reward.

Possible Location: Waste Disposal

As these rats are located in the Waste Disposal area, you must backtrack to complete the side quest. The first rat would be fairly easy to spot as you will find it on the ground right as you enter the Waste Disposal. However, as this place contains piles of rubbish, it is better to listen for these rats, making it easier to spot them.

Moreover, for the second rat, you would again require Ashley to bring up the small bridge by rotating the wheel. Just cross the bridge, and the rat would be on the ground, running around.

You would need to backtrack even more to find the third and the fourth rat. Once you have crossed the bridge, head deeper into the Waste Disposal Area. Although, be careful, as a Regenerator might be waiting for you right at the entrance. Moreover, as this is later on in Chapter 14, be careful as this Regenerator can mutate into Iron Maiden.

Just kill the Regenerator using your Biosensor Scope. Now you have to be alert and listen for the rats. The third and fourth rats will be on the ground fairly close to each other.

Once you have killed all four rats, head back to Ashley and continue your main campaign.

You can now head back to the Merchant at the Cargo Depot’s entrance. Just interact with the Merchant, and you will receive your reward. The reward here is the same as the previous Pest Control Request, and you will earn 3 Spinels after exterminating 4 Rats. Although, these Spinels are extremely useful and can be used to trade several vital items from the Merchant.


The Merchant Requests is an exciting feature for the Resident Evil 4 Remake. This adds gameplay variety to the game and gives its players a much-needed break from the main campaign. Although, these are not mandatory for your main campaign. Yet, it still gives the players a chance to earn precious Spinels that are much more difficult to find in the game. These Spinels can then be traded for several useful items from the Merchant.

The Pest Control is a series of such Merchant Requests, where you can earn Spinels. Moreover, this Merchant Request, similar to other requests, requires you to kill an animal for the Merchant. However, here you do not need to bring the animals back to the Merchant.

During Pest Control, you are tasked with killing rats that are spread over the current area you are in. There are only three Pest Control missions spread out over various Chapters, so keep your eye open for them.

Furthermore, as these Rats are fairly quick and small, it is better to listen for their sound to narrow down their location. So if you need a few Spinels, it is better to complete these Merchant Requests. You will be rewarded fairly if you exterminate all the Rats and help out the Merchant.
