How Bed Bugs Spread, and How to Prevent It – Healthline

Bed bugs are small, wingless, oval-shaped insects. As adults, theyre only about one-eighth of an inch long.

These bugs are found across the world and can survive in places between 46 degrees and 113 degrees Fahrenheit. They usually live close to where people sleep, generally within eight feet of a bed.

Bed bugs feed on blood. They dont spread disease but are a nuisance and their bites can be itchy and irritating.

Because they dont have wings, bed bugs move around by crawling. But in many cases, people carry bed bugs from place to place, often without realizing. But there are a few steps you can take to help prevent bed bugs and stop their spread.

Female bed bugs lay five to seven eggs per week. This adds up to over 250 eggs in a lifetime, with proper feeding.

The eggs take approximately 10 days to hatch. After hatching, bed bugs go through five nymph (youth) stages before they become adults. In between each stage, they shed (or molt) their exoskeleton. Bed bugs need to feed at least once before each time they molt, but they can feed up to once a day. It takes two to four months for bed bugs to become adults.

Bed bugs dont have wings, so they have to crawl to move around on their own. This means that in some cases, infestations will spread slowly. But they can move within walls, through floor and ceiling openings, and on pipes.

But most bed bugs spread from place to place when they get onto peoples clothes, linens, or furniture and into luggage. People will then move the bed bugs from place to place much quicker than the bed bugs could infest new areas on their own.

Bed bugs, unlike lice, dont travel directly on people and spread from person to person. But they can travel on peoples clothes. In this way, people can spread bed bugs to others, without even knowing it.

The best way to stop the spread of bed bugs is to regularly inspect for signs of an infestation. That way, you can take care of any bed bugs early, before they start to spread. Other ways to help stop the spread of bed bugs include:

Bed bug infestations can be very annoying. Although they dont spread disease, you can end up covered in itchy red bites.
