Are there cockroaches in Ireland? Spring tips for a roach free home

If you’re asking, are there cockroaches in Ireland? the answer is sadly yes, and it’s becoming more visible.

Cockroaches on the rise in Irish cities

In the last year alone, several food businesses in Dublin have been forced to close after inspectors found cockroaches. Most recently, in January 2025, a cafe on Talbot Street was closed temporarily after dead cockroaches and egg cases were found among the crockery and utensils. It’s a wake-up call that these pests can pop up in any urban environment if the conditions are right.

Why do I care about cockroaches?

Health Risks

Cockroaches can spread bacteria like salmonella, staphylococcus and streptococcus making them a big problem for homes and businesses.
They rummage through sewers, drains and rubbish before entering living spaces and contaminate food, utensils and surfaces along the way.
Their droppings, saliva and shed skins can exacerbate allergies or asthma in sensitive people.

Reputation Damage

For businesses, nothing will tarnish a brand faster than a cockroach sighting. Word travels fast, especially on social media.
Enforcement notices can come with big fines or legal trouble for repeat offenders.

Rapid Reproduction

Many cockroach species thrive in warm, humid environments. One female German cockroach can carry an ootheca (egg case) with 35-40 eggs. If not addressed, this can quickly turn into a big problem.

Common Cockroach species in Ireland

Though there are thousands of cockroach species worldwide, only a handful become pests in human habitats. German and Oriental Cockroaches are the two you’re most likely to find in Ireland, but American Cockroaches also appear where indoor temperatures are warm.

German Cockroach (Blattella germanica)

Loves heat and humidity (sometimes called “steam flies”).
Found behind appliances with warm motors (fridges, ovens) or near boiler rooms.

Oriental Cockroach (Blatta orientalis)

Prefers cooler damp areas (basements, drains or outside bins in milder weather).
Found around water sources like sinks and pipes.

American Cockroach (Periplaneta americana)

Larger and found in warmer indoor environments; can appear in centrally heated buildings or commercial kitchens.

Why Spring is the time to talk Cockroach prevention?

Though cockroaches are active year-round, spring’s mild weather encourages them to move around more and breed.

Add to that increased travel (they’re notorious hitchhikers), and you could end up with unwanted six-legged roommates. By acting now, you can save yourself costly treatments and stress later.

Cockroach Control at Home: First Steps

1. Identify & Monitor

- Use sticky traps or “cockroach boards” to see if roaches are active.
- Check warm spots like behind the fridge or oven.
- Look for droppings, egg cases or shed skins, especially near food or water sources.

2. Clean Thoroughly

- Roaches are attracted to leftover crumbs and food residue. Pay special attention to hidden spots under appliances, behind cabinets and in pantries.
- Keep bins covered, clean and emptied regularly.

3. Eliminate Moisture

- Cockroaches need water. Fix leaky taps and pipes, dry any damp areas and ventilate rooms prone to humidity.

4. Seal Entry Points

- Block up cracks around windows, doors and where utility lines enter your home.
- Check second-hand appliances (like fridges and freezers) for hidden insects before bringing them indoors.

5. Tackle Clutter

- Piles of newspapers or cardboard boxes make excellent roach hiding spots. So, reduce clutter and store items properly.

Cockroaches in Commercial Settings

Food & Drinks Industry: Restaurants, cafes, bars and any business handling consumables must be extra vigilant, especially in city centres like Dublin.
Enforcement Notices: Failure to maintain a roach-free environment can result in big fines or even forced closures by the Food Safety Authority of Ireland (FSAI).
Reputational Risks: Cockroaches spread fast through negative reviews and can harm long-term customer trust.

Final Thoughts: Stay Ahead of the Spring Surge

Recent closures in Dublin and enforcement notices are proof that cockroaches can strike anywhere—from homes to restaurants. By being on top of cockroach prevention—through cleaning, sealing entry points and acting fast when you see the first signs of activity—you can save yourself stress, health risks at home and costly closures for your business. If you do get an infestation, a cockroach exterminator will make sure they’re gone for good.
