Ways Through Sewer Rats Enter the House

Ways Through Sewer Rats Enter The House

Dealing with sewer rats can be a nightmare for many homeowners.

These unwanted visitors can cause all sorts of damage, from holes in walls to contaminated food and water sources.

Identifying if you have sewer rats is essential for quickly and effectively dealing with them.

Below are some of the ways sewer rats enter the home:

1. Through Poorly Sealed or Missing Pipes

Through Poorly Sealed Or Missing Pipes

The most common way sewer rats enter the home is through poorly sealed or missing pipes and drains, which provide easy access to the house’s interior.

This includes floor drains, plumbing vents, and other small openings around the plumbing fixtures.

Additionally, these pests can find their way into a home through crawl spaces and foundation cracks.

Once inside, they will often stay close to water sources such as sinks, toilets, or other wet areas to keep them hydrated.

2. Through the Plumbing System

Through The Plumbing System

Sewer rats are a common nuisance for homeowners across the globe.

These rodents manage to enter buildings through plumbing systems, making their way from sewers and up through toilets and other fixtures.

Rats are fantastic climbers and can efficiently make their way up the pipes of plumbing systems to gain access to houses or buildings.

This means that even if a building is situated far away from sewer lines, it’s still possible for a rat to climb up the pipes easily.

Once inside, that can spread disease, damage belongings, or cause structural harm-all signs of an unwelcome guest!

3. Through Small Openings

Through Small Openings

Rats are well known to be able to gain entrance into buildings through small openings such as cracks and holes, but only some people know that they can also squeeze their way through many other small spaces.

Sewer rats, in particular, have been known to use small cracks in walls, floors, ceilings, and around windows and doors to gain access to buildings.

Sewer rats are adept climbers who can scale walls easily; however, when the opening is too narrow to climb through directly, they will often use their flexible bodies and sharp claws to squeeze their way inside.

Rats compress their body up to 60%, enabling them to pass through gaps that seem far too narrow for them.

How Can I Prevent Rats From Coming Inside

How Can I Prevent Rats From Coming Inside

Having rats in your home can be annoying, and prevention is key.

Stopping sewer rats from entering your home before they have the chance is the best way to keep them away.

1. Use Rat Blockers

Use Rat Blockers

Rat blockers are a simple and effective way to keep rats from entering your house.

The blockers prevent rodents from entering the inspection chamber outside the house, which is the entry point for most rats.

The blockers consist of a stainless steel plate with two or three holes.

These holes are designed to prevent rats from passing through while allowing water to flow freely. Any rainwater can normally escape while ensuring no rodents can enter your home.

Installation usually only takes a few minutes and requires no additional tools or expertise, making it an easy task for any homeowner looking for extra protection against pests.

2. Use Rat Traps

Use Rat Traps

One of the most compelling ways to get rid of rats is using traps.

Rat traps come in many different sizes, shapes, and materials depending on the environment you need to trap the rat in.

The most common type of rat trap is a snap trap, which uses a spring-loaded bar that quickly snaps shut when triggered by the rodent’s movements.

These types of traps are generally more humane than other methods but may not be suitable for small children or pets as there is risk associated with them.

3. Other Options

Other Options

Additional options for preventing rats from coming inside include the following:

  • Live capture traps will allow you to safely transport rats away from your property.
  • Glue boards will immobilize them until you can remove them.
  • Electronic rat zippers can effectively repel them.

4. Call Professionals To Help
