What Are Bed Bugs and What Do They Look Like?
Bed bugs are very small insects with the scientific name Cimex lectularius. They act like tiny thieves, living by drinking the blood of humans and animals. This makes them parasites. They usually come out to feed on your skin while you sleep at night.
Let us look at what bed bugs actually look like:
- Adult bed bugs are flat, brown, or reddish-brown with six legs. They are about the size of an apple seed, measuring roughly five to seven millimeters long.
- Young bed bugs, or nymphs, have a whitish-yellow color. Sometimes they look see-through if they have not fed on blood yet.
- Bed bug eggs are very tiny, looking like the tip of a pin with a pearly white color. If an egg is older than five days, you might spot a tiny dark dot inside it.
Think about this: a single female bed bug can lay between 200 and 500 eggs in her lifetime. Even if you start with just a few bugs, you can face a massive problem in a short time.
Where Do Bed Bugs Live and Where Do They Hide?
Bed bugs are surprising creatures that can live in five-star hotels, normal houses, dormitories, and public transport like buses, trains, and ships. You can find them in almost any corner of the world.
Bed bugs usually live within eight feet of where you sleep. They are most active during the night hours.
During the day, these bugs hide in various spots around your bed. Here are common hiding places:
- Along the seams and edges of your mattress.
- Inside the box spring, bed frame, and behind the wooden headboard.
- Between the cushions and along the seams of bedroom chairs and sofas.
- Inside the joint corners of bedroom drawers and bedside tables.
- In any small crack, crevice, or fold near your bed.
- Along baseboards and behind loose wallpaper edges near power outlets.
An adult bed bug usually lives for six months to two years. They feed every three to seven days. The amazing part is that they can survive for months, or sometimes even a year, without any food at all.
How Do I Know for Sure If My House Has Bed Bugs?
The first sign that you have bed bugs is usually getting bitten by one. If you notice bites and want to check your home, look out for these clear signs:
- A sweet, musty odor in the room.
- Rust-colored stains on your bedsheets, nightclothes, or nearby items. These stains come from waste that bed bugs leave behind after feeding.
- Exoskeletons left behind as bed bugs shed their skin while growing larger.
- Live bed bugs hiding in the folds of bedding or along mattress seams.
Bed bugs also move a bit slower than other small insects. If you spot one, watch how fast it crawls to help confirm what it is.
Who Do Bed Bugs Bite the Most?
Bed bugs can bite anyone. The unfortunate truth is that no matter how clean you keep your home, stopping bed bugs from arriving can be difficult. These bugs are expert travelers.
They hitch a ride on luggage, folded clothes, used mattresses, old furniture, and boxes to enter your home. If you live with many people or travel often, your chance of bringing these unwanted guests home increases.
Imagine returning from a wonderful vacation without knowing that a couple of bed bugs hid in the corner of your bag. Within days, you realize a brand-new problem has started in your home!
How Common Are Bed Bugs?
