Bed Bugs
Bed bugs are small, wingless insects that are roughly 5mm in length—about the size of an apple seed. They possess a flat, oval-shaped body that is typically brownish, though they turn a deep reddish-purple and become engorged after a blood meal. As they feed primarily on humans and animals during the night, they are particularly unwelcome guests in Irish homes, hotels, and guesthouses.
These pests are prolific breeders and exceptional hitchhikers. They often enter a property by clinging to luggage, clothing, or second-hand furniture and couches. Because of their incredibly thin profile, they can squeeze into gaps no thicker than a credit card. While mattresses, bed frames, and headboards are their primary "hot spots," they also hide behind loose wallpaper and inside bedside lockers to stay close to their host.
In Ireland, the most prevalent species is Cimex lectularius. It is a member of the Cimicidae family, which also includes the Bat Bug—a close relative that looks almost identical to the bed bug under a microscope but prefers to feed on bats. While both male and female bed bugs bite, females do so more frequently as they require blood to develop their eggs.

The Rising Challenge
As international travel for business and staycations becomes more frequent, the risk of inadvertently transporting these pests grows. Bed bugs have become a significant concern in student accommodation, care homes, and even on public transport like buses and planes. Once bed bugs establish a foothold, they can easily migrate through wall cavities and floorboards to infest neighbouring rooms or properties.
Essential Bed Bug Facts
- Rapid Reproduction: A single female bed bug can lay between 200 and 500 eggs in her lifetime, typically in batches of 10 to 50.
- Egg Placement: Eggs are usually tucked away in mattress seams, bed linen, or furniture joints, secured by a transparent, glue-like substance.
- Life Cycle: There are seven stages from egg to adult. While this can take as little as 45 days in favourable conditions, the process can extend up to a year.
- Resilience: An adult bed bug can survive for several weeks—and in some cases, months—without a blood meal, patiently waiting for a host to return.

Rentokil: Professional Bed Bug Solutions
If you detect signs of activity, our local expert teams can provide immediate guidance. Bed bugs are notoriously difficult to eliminate with "off-the-shelf" DIY products because they are masters of concealment and can survive long periods of dormancy. Since missing just one pregnant female or a few eggs can lead to a total re-infestation, professional intervention is often vital.
Our Treatment Options
- Insecticidal Treatments: We use professional-grade residual sprays designed to target bugs in their hiding places.
- Entotherm Heat Treatment: Our award-winning, chemical-free heat pod is a non-toxic solution. It works by raising the temperature to a level that is lethal to all life stages—including the resilient eggs—in a single application. This is ideal for sensitive environments like hospitals, hotels, and family homes.

Frequently Asked Questions
-
Where do bed bugs hide most often?
In Ireland, we commonly find them in:
- Bed frames, headboards, and mattress seams.
- Underneath carpets, rugs, and floorboard gaps.
- Behind skirting boards and peeling wallpaper.
- Inside wardrobes, drawers, and bedside lockers.
-
Are bed bugs dangerous?
While they aren't known to transmit diseases, their bites cause significant irritation, swelling, and distress. Scratching the bites can lead to secondary skin infections. Furthermore, the psychological impact of an infestation can be severe, often requiring professional resolution to restore peace of mind.
-
Why shouldn't I treat bed bugs myself?
DIY methods rarely reach the deep crevices where eggs are hidden. Furthermore, some populations have developed a resistance to standard shop-bought insecticides. Professional pest control is the only way to ensure the entire life cycle is broken and the infestation is fully eradicated.
-
Which bed bug treatment is most effective?
For most customers, the Entotherm Heat Treatment is the gold standard. Because it reaches every corner of a room or piece of furniture, it eliminates the need for multiple chemical applications and allows for much faster re-entry into the room.
