How Do You Get Rid of Rats? Expert Commercial & Residential Rat Control in London & Essex

Hearing scratching in the walls, spotting droppings under the sink, or noticing gnaw marks on skirting boards — these are early signs that rats may have found their way into your home. And once they’re in, they won’t leave on their own.

To get rid of rats effectively, you need a combination of the right techniques: sealing all access points, using the correct traps, removing attractants, and knowing when professional help is necessary. This guide explains how to eliminate rats safely and permanently, specifically for homes in East London and Essex where lofts, extensions, and cavity walls create ideal rodent routes.

Key Takeaways

• Seal entry points using steel wool, mesh, or professional rodent-proof materials.
• Snap traps remain the most effective DIY option when placed correctly.
• Natural deterrents support prevention but won’t eliminate an active infestation.
• Professional rodent control remains the fastest and safest long-term solution.
• Regular inspections help detect activity early and prevent reinfestation.

How to Identify a Rat Infestation

Seeing one rat usually means there are more. Rats are social animals and rarely travel alone. Look for:

Reliable signs of rat activity

• Dark, pointed droppings
• Grease smear marks along walls
• Scratching or scurrying in lofts or behind walls
• Chewed wires, pipes, or food packaging
• Nesting material under units or in boiler cupboards
• Tracks behind appliances or along skirting

Rats can carry harmful bacteria such as leptospirosis, so identifying activity early is important for health and safety.

Most Effective Rat Trapping Methods

Trapping works best when it’s done with the correct approach.

Snap traps

Still the most reliable DIY tool. Place them:

• Along walls
• Under kitchen units
• Behind appliances
• In loft spaces
• Where droppings or smear marks are found

Baits such as peanut butter or dog biscuits work well because rats can’t remove them without triggering the mechanism.

Many online hacks claim quick results, but most don’t work in real-life conditions. Our detailed guide on peanut butter and baking soda for rats explains why this mixture is unreliable — and potentially dangerous.

Live traps

Suitable for occasional intruders, but releasing rats outdoors in urban areas is rarely appropriate and may breach regulations.

Glue boards

Heavily restricted in the UK and should only be used by trained professionals.

Do Natural Deterrents Work?

Essential oils like peppermint and eucalyptus can make an area less attractive to rats, but they cannot clear an active infestation.

They are best used as:

• Ongoing prevention after professional treatment
• Deterrents around bin areas, sheds, or low-traffic parts of the home

Useful options include:

• Peppermint oil–soaked cotton balls
• Catnip plants
• Black pepper or chilli deterrents

But again — these will not resolve the root problem.

Seal All Entry Points (The Only Permanent Fix)

Proofing is the most important — and most overlooked — part of rat control. If you don’t stop access, they will return.

Common entry points

• Gaps under kitchen units
• Holes around pipework
• Redundant openings in brickwork
• Damaged air bricks or vents
• Gaps in loft eaves or extensions
• Openings around boiler flues
• Gaps under external doors

Materials that actually work

• Steel wool
• Copper mesh
• Rodent-proof cement
• Galvanised mesh
• Specialist proofing strips

In terraced or semi-detached homes, rats often travel between adjoining properties. If activity may be coming from next door, read our guide on what to do if your neighbour has rats.

When to Call a Professional

DIY trapping can help, but rats in London often nest in places you simply can’t reach without professional tools, including:

• Under floorboards
• Behind kitchen kickboards
• Inside cavity walls
• In loft insulation
• In garden sheds or bin stores

Professional treatment usually includes:

• A full inspection
• Identification of all access points
• Safe use of professional-grade rodenticide inside locked stations (if appropriate)
• Activity monitoring
• Follow-up visits
• A proofing plan to stop future entry

Frequantly Asked Question

1. What is the quickest way to get rid of rats?

The fastest way to get rid of rats is to combine snap traps with proper placement, remove food sources, and seal all entry points. Professional pest control is the quickest guaranteed method for full eradication.

2. Will rats leave on their own?

No. Rats rarely leave a property voluntarily because food, warmth, and nesting materials keep them there. They must be removed through trapping, proofing, and professional treatment.

3. How do rats get into UK homes?

Rats enter through small gaps around pipework, broken air vents, damaged brickwork, under kitchen units, and rooflines. Terraced and semi-detached homes often share access points between properties.

4. What smell keeps rats away?

Strong scents such as peppermint oil, eucalyptus and black pepper can discourage rats, but they do not remove infestations. They work best only after proper proofing and treatment.

Summary

Getting rid of rats requires more than traps or deterrents — it requires understanding how they enter your property and blocking those access points permanently. Traps can help reduce numbers, deterrents can support prevention, but proofing and professional treatment are what actually solve the problem long-term.
