Why Do I Have Bed Bugs?

Bed bugs might be one of those pests that you hear about but never expect to encounter. Unfortunately, it’s quite common to experience a bed bug infestation. There are several ways you might introduce bed bugs into your home.


Once you understand more about these pests, you’ll be able to determine whether you have an infestation and figure out how to get rid of them.

  1. During the day, bed bugs hide in crevices and mattress seams. During the night while people are sleeping, bed bugs become active to feed.

    1.Bed Bug Overview

    Bed bugs are small reddish-brown bugs that do not fly. These bugs feed on blood to continue their lifecycle of laying eggs. Bed bugs exist around the world – on virtually every continent. The presence of bed bugs is not an indication of cleanliness – bed bugs can exist in both clean and filthy conditions.


    During the day, bed bugs hide in crevices and mattress seams. During the night while people are sleeping, bed bugs become active to feed. Although bed bugs do not carry disease, their bites can be itchy. The presence of bed bugs can cause sleeplessness and the bites may become infected from itching.

  2. 2.Signs of a Bed Bug Infestation

    There are several clues you can look for to determine whether you have a bed bug infestation. The biggest clue that you may have bed bugs is your own body. If you or people in your family have welts or bites on the legs, arms, neck or face, this is a strong indication you may have bed bugs. Not everyone reacts to bed bug bites in the same way, however. Some people don’t swell or itch at all and other people have severe reactions. In addition, it may take up to two weeks for bite marks to appear on the skin.


    Additional signs of a bed bug infestation include finding exoskeletons from the bed bugs that they leave behind after molting. This debris may show up in bedding, in mattress crevices or on the floor. You may also find the actual bed bugs themselves on the mattress and within the sheets. It’s also common to notice rusty spots and stains on bedding and mattresses that comes from bed bug excrement. You may also notice an unusual odor in sleeping areas.

  4. 3.Reasons for Bed Bug Infestation

    One of the most common causes of a bed bug infestation is bringing them home from an infested location. If you visit someone’s home or a hotel that has bed bugs, you may bring some bugs home with you in your luggage. Once you introduce bed bugs into your own home, they will multiply rapidly. Because of the small size of bed bugs, it’s easy to miss them. In addition, bed bugs can last for many months without feeding so they can remain hidden in luggage for an extended time.


    Although bed bugs are annoying and upsetting, it may help to know that anyone is at risk for a bed bug infestation. If you travel frequently, it’s likely that you’ll unwittingly bring some home with you eventually. In fact, even some of the most posh hotels suffer bed bug issues.
