Introduction:
If you’ve woken up with itchy spots or found a stray insect crawling on your sheets, your first thought is probably one of worry. We see this all the time at Bath Pest Controllers. The fear of an infestation is high, especially in a city like Bath where our historic buildings and close-knit terraces make it easy for pests to move around. But before you panic, you need to know exactly what you are dealing with.
Many people struggle to identify these insects because they are small and secretive. In this guide, we’ll talk about what does a bedbug look like, their strange survival habits, and the best ways to get them out of your home. We take these issues seriously because we know that your home should be your safe space, not a place where you feel uncomfortable.
Can You See Bed Bugs with the Naked Eye?
One of the biggest myths we hear is that these insects are too small to see. People often think they are microscopic, but that isn’t true. So, can you see bed bugs with the naked eye? Yes, you can.
While they are small, an adult bed bug is about the size of an apple seed. They are flat, oval-shaped, and usually a brownish colour. If they have just eaten, they change shape and colour—becoming longer, more bloated, and dark red.
Younger bed bugs, called nymphs, are much harder to spot. They start out nearly translucent or a pale yellow. Unless they have recently fed, they can almost blend into the colour of your mattress or sheets. Their eggs are even smaller, roughly the size of a speck of dust, and are a milky-white colour. We often tell our clients to look for the “evidence” they leave behind, which is often easier to find than the bugs themselves. If you are worried about what you’ve found, you can read our guide on the 10 clear signs of bed bugs you should never ignore to help confirm your suspicions.
Do Bed Bugs Have Wings?
When people see a bug in their bedroom, they often hope it’s just a beetle or a small fly that wandered in through the window. This leads to the question: do bed bugs have wings?
The answer is no. Bed bugs do not have wings and they cannot fly. They also don’t jump like fleas. If you see an insect flying around your bed or jumping from the carpet to the duvet, it isn’t a bed bug.
Bed bugs move by crawling. They are quite fast for their size, but they rely on hitchhiking to get from house to house. They hide in suitcases, coats, or used furniture. Because they can’t fly, they stay close to where their “food” (us) sleeps. They spend most of their time tucked away in the seams of mattresses, behind headboards, or in the cracks of bed frames.
The Bed Bug Life Cycle: From Egg to Adult
To understand how a small problem becomes a massive one, you have to look at the bed bug life cycle. It is a process of “incomplete metamorphosis,” which means they don’t have a pupa or cocoon stage like a moth or a butterfly.
The Egg: A female lays between one and five eggs a day. These are glued into cracks and crevices. They hatch in about six to ten days.
The Nymph Stages: Once they hatch, the babies (nymphs) look like miniature versions of the adults. They have to go through five stages of growth. To move from one stage to the next, they must have a blood meal. Each time they grow, they shed their skin.
The Adult: After about five weeks (if the room is warm and food is plenty), they become adults. Once they reach this stage, they are ready to start breeding and laying eggs of their own.
This fast cycle is why we recommend getting professional help early. If you leave a few eggs behind, the whole process starts again in a matter of days. We’ve been helping families in Bath for years, and our team at Bath Pest Controllers knows exactly where to look for these hidden eggs and nymphs.
How Long Do Bed Bugs Live?
Another thing that makes these pests so difficult to deal with is their stamina. When people ask how long do bed bugs live, the answer usually depends on the temperature of your house.
In a typical warm home in Bath, an adult bed bug usually lives for about four to six months. However, in cooler conditions, their metabolism slows down, and they can live significantly longer. Some have been known to survive for up to a year under the right circumstances.
They are incredibly hardy. Unlike many other insects that die off quickly without food or in the cold, bed bugs are built to wait. This is why “leaving the room empty” for a few weeks never works to get rid of them.
Survival Instincts: How Long Can Bed Bugs Live Without a Host?
This is the most common question we get from people who are considering moving out of their bedroom to “starve” the bugs. How long can bed bugs live without a host?
You might not like the answer. In a standard room temperature environment, a bed bug can easily go for two to three months without a blood meal. In colder environments, some laboratory studies have shown they can survive for much longer—even up to a year—without feeding.
They enter a state similar to hibernation where they save their energy and wait for a host to return. Because they are attracted to the carbon dioxide we breathe out and our body heat, they will simply stay tucked away in the walls or the bed frame until they “sense” someone sleeping in the bed again. This is why we always say that “starving them out” is not a viable method for the control of bedbugs.
Types of Bed Bugs
While there are many species of “cimicids” (the family they belong to), only a few actually bother humans. When looking at the different types of bed bugs, we usually focus on two:
Common Bed Bug (Cimex lectularius): This is the one we find in 99% of our call-outs in Bath. They are found all over the world and have adapted perfectly to living in our homes.
Tropical Bed Bug (Cimex hemipterus): As the name suggests, these prefer warmer climates, but with global travel, they do occasionally turn up in the UK. They look almost identical to the common variety and behave in the same way.
Bat Bugs and Bird Bugs: These look very similar to bed bugs but they usually live in lofts or eaves. They prefer to feed on bats or birds, but if their host leaves (like when bats migrate or birds fly the nest), they might wander into the living areas of your house and bite humans.
Knowing which type you have is important because the “source” might be different. If you have bat bugs, treating the mattress won’t help until the loft issue is resolved.
Control of Bedbugs: Why Professional Help is Best
We know it is tempting to go to the shop and buy a can of spray. But the control of bedbugs is one of the hardest jobs in the pest control industry.
These insects have developed a high resistance to many common household chemicals. If you spray a cheap product, you might kill a few on the surface, but you will also irritate the rest. This causes them to scatter. Instead of having bugs in just your bed, you might end up with them in your sofa, your curtains, and even behind your picture frames.
Our approach involves:
Detailed Inspection: Finding every hiding spot.
Targeted Treatments: Using professional-grade products that the bugs aren’t resistant to.
Heat Applications: Using steam or heat to kill eggs that chemicals can’t reach.
Follow-up: Making sure the life cycle is completely broken.

Managing the Issue in Bath Homes
Bath has a lot of charm, but our older buildings provide a lot of “housing” for bed bugs. From gaps in floorboards to space behind decorative coving, there are many places for them to hide. We take a serious, statistical approach to clearing these pests. We don’t just guess; we use our knowledge of their biology to outsmart them.
We also believe in being honest with our clients. Getting rid of bed bugs is a team effort. We provide the expertise and the treatments, and we ask you to help with things like high-heat laundry and reducing clutter. Together, we can make sure your home is clear.
If you suspect you have found a bed bug, try to catch it in a clear jar or take a photo. Having a bed bugs image for us to look at can speed up the process and get your treatment started sooner.
Don’t let the problem grow. If you are worried, contact us today. We are here to help you resolve this serious issue quickly and effectively.
After a meal, a bed bug looks very different. It changes from being flat and brown to being elongated, swollen, and a bright or dark red colour. It looks almost like a small, red torpedo. This change happens because they can drink up to six times their body weight in blood in a single sitting.
Yes, they can. While they prefer to be close to the bed, if an infestation is large, they will hide under the edges of the carpet, especially near the skirting boards. They use the carpet as a highway to move from the bed to other pieces of furniture like sofas or wardrobes.
They are mostly nocturnal, but they are also opportunistic. If you work night shifts and sleep during the day, they will adjust their schedule to feed when you are still. If they are very hungry, they will even come out in a lit room to find a host.
It is a common situation. Actually, both of you are likely being bitten, but only one of you is reacting. The "bite" is an allergic reaction to the saliva the bug injects. About 30% of people show no physical reaction at all to bed bug bites, so it might look like they are being ignored when they aren't.
Unlike mosquitoes or ticks, bed bugs are not known to spread diseases to humans. The main risks are secondary skin infections from scratching the bites and the significant psychological stress, anxiety, and lack of sleep that comes with an infestation.
