Which Rat Bait Works Best For Rat Traps?

Rats are smart, cautious, and incredibly resourceful. If you’ve heard scratching in the loft, spotted droppings under the sink, or seen activity in the garden, your first thought is often:
“What’s the best rat bait to use?”

The truth is simple:
Some DIY baits can attract rats to traps temporarily, but they rarely provide a long-term solution.
This guide shows you which household foods work best for baiting snap traps, what to avoid, and when it’s time to call in a rat control professional.

What Actually Works? The Best Natural Baits for Traps

When using snap traps (the only DIY method we recommend), these baits consistently perform better than others:

1. Peanut Butter – one of the most reliable options

It’s sticky, aromatic, and forces the rat to work to get it—making it more likely to trigger the trap.

2. Chocolate Spread or Nut Butter

Sweet, oily foods attract rats far more than cheese ever will.

3. High-fat, high-protein scraps

Small pieces of cooked bacon, sausage, or chicken skin can work well because rats follow strong smells.

These baits mimic the high-calorie food rats normally scavenge around bins, takeaways, and communal areas across East London and Essex.

What Doesn’t Work? (Forget the Cartoons)

Cheese

It’s simply not attractive enough for most UK rat species.
Rats prefer high-fat, high-energy foods—not bland dairy.

Dry food pieces

Crackers, bread, cereal, or anything that dries out quickly loses its scent and becomes pointless.

Large bait piles

More bait = more nibbling without triggering the trap.
A pea-sized amount is enough.

Common DIY Trapping Mistakes

Homeowners often tell us, “I’ve used traps but nothing is happening.”
That’s rarely because of the bait alone.

The biggest issues we see are:

1. Wrong trap placement

Traps should sit flush against walls and along rat run lines—not in the middle of a room.

2. Human scent on traps

Rats are cautious. Handling traps without gloves makes them suspicious.

3. Expecting instant results

Rats often approach slowly, test the bait, and return only when they feel safe.

4. Ignoring how many rats are actually present

If you’re catching nothing, or you catch one but the noise continues, that’s usually a sign of a larger issue that traps alone won’t fix.

Peanut Butter + Baking Soda Myth: Does It Work?

This mixture is one of the most Googled rat “remedies” in the UK—so much so that Google often serves Bugwise articles for this query.

The reality:

Peanut butter and baking soda does NOT work as a reliable rat killer.
Rats quickly detect anything unusual in food, and this mixture is nowhere near effective enough to eliminate an infestation.

Peanut butter is excellent as bait, but it won’t resolve a rat problem on its own.

A Fair Warning About DIY Baiting

Using food as bait in snap traps can help you catch one or two rats, especially early in an infestation.

But it cannot:

• identify entry points
• stop rats returning
• locate manholes/drain defects
• remove nests in loft insulation
• resolve structural access issues
• deal with burrows in gardens
• tackle larger numbers

DIY baiting is temporary.
Rats breed quickly and spread fast.

That’s why many homeowners in Romford, Barking, Ilford, Dagenham, Upminster and surrounding areas end up calling us after trying DIY for a few days.
