Bed Bug Size

If you live in an area where there have been reports of Bed Bugs or suspect you may have them, you need to get an inspection right away. Its important to note that bed bug size is dependent on the stages of development.  You may not always be able to see them, but you could have them.  If you live in an apartment building, in particular, they can travel extremely fast. Bed bugs can also travel on a person; this is so they can jump or move outside of the place they currently reside.

Bed Bugs

If you have adult bed bugs, they are quite visible. Generally about the size of an apple seed, and they live off of blood. Not just human blood, though. They may also attack your pets.   Bed bugs have been with humans for more than 3,300 years and are found everywhere people gather, not just in your home. They are commonly found in hotels, schools, offices, retail stores, and on public transportation.   They can quickly get into your purse, briefcase, suitcase, jacket and therefore can travel long distances. They can be confused with similar-looking bugs, so often, people are not always aware they have them.  It can also be challenging to recognize their bite marks. This allows them to infest the area quickly as you may be unaware that you have them.

Bed Bug Size Can Vary

If you suspect you may have bed bugs or are trying to be vigilant about keeping them away, you must know what to look for.  While they may vary, bed bugs are usually oval and are not very big. Maybe only 3/16th of an inch long. Before they feed, they are brown and flat, but after, bed bugs become redder and more prominent. Bed bug nymphs can be harder to see, as they are smaller and paler.

Bed bugs have six (6) legs and two (2) antennae. The adult bugs will be identified relatively quickly, as can their fecal droppings. You will see either on your mattress or mattress seams and on the box springs, other upholstery, or even the floor or walls.

If these spots are found, take it as a good indication you have an infestation. Bites on the arms and legs are also a good sign you have them, notably a series of bites all in the same place.  These small little bites can be itchy and swell and may cause other irritations. They can be from other insects, like mosquitoes or ants, so make sure you check for bed bugs to be sure.  They also shed their skin, their eggs, empty eggshells, besides the bugs themselves. While these items are relatively small, you should still be able to see them. Bed bugs and their eggshells appear pale white after molting or emerging from the eggshell.

Stages of Bed Bugs

Even if you sprayed or took all the precautions needed to get rid of or prevent bed bugs, even missing one-bed bug with eggs can mean a massive outbreak. The female can lay anywhere from one to five eggs every day. Out of the seven (7) stages of the bed bug’s journey to maturity, it only takes about five (5) weeks for a hatched nymph to reach adulthood. 


The eggs, which have a milky white color to them, are about one millimeter in length or the size of a few grains of salt, which will be hard to see.  


1st stage nymphs are 1.5 millimeters in length. As soon as they come out of their eggs, they can start feeding immediately. This will depend on the temperature and the food supply. As they feed and grow, they molt. This continues through the second to the sixth stages of their life. They continue to grow and molt through five stages. They will grow up to about 4.5 mm, or the size of an apple seed, when mature. 

  • 1st stage nymph (1.5 mm).
  • 2nd stage nymph (2 mm).
  • 3rd stage nymph (2.5 mm).
  • 4th stage nymph (3 mm).
  • 5th stage nymph (4.5 mm).


It takes about five weeks for a nymph to become an adult, although it can take several months depending on conditions. Once they hit maturity, they can breed. A bed bug’s lifespan is generally about four to six months, but under the right conditions can live up to a year.

Prevention and Removal | Bed Bug Size

If you found out one of your neighbors or someone you know or come in contact with has bed bugs, you should take preventive measures right away.  Because the stages of bed bug size can vary you should not assume you don’t have an infestation if you cant see them.

Get Rid or Clean Contamination Items

  • Remove a lot of the clutter around your home, particularly around your bed. If you have boxes, bags, or other items stored under your bed, remove them. This must include stuffed toys, blankets, additional bedding, smaller electronics, and anything usually there. 
  • Bag the items where they are to prevent moving the bugs to another room or area. Take the items for laundry or disposal right away.
  • Launder sheets and other items on hot water. If you want to spray them first, do it while they are in the bag. Dry them on hot for at least 30 minutes, and make sure you discard the plastic bags.
  • Check out all your sockets, as they can get in there and live. It’s warm in there, which is what they like.
  • Take your bed frame apart and spray and clean all the little places they can hide and hang out.
  • Treat your mattress and then cover the mattress and box spring with encasements. Once the encasements are on, the bugs can’t get in or out. If you can still see them inside, you can leave them, as they will have nothing to feed on and perish.

Call EnviroPest Bed Bug Exterminators

It is your landlord’s responsibility to let you know if someone in the building has bed bugs in most places. They should also take at least partial responsibility for the treatment.  While do-it-yourself methods can work, you are better off calling a pest control expert to help you. They can come in; they know where to look and what to do to get rid of them.
