How Long Can Bed Bugs Live in a Mattress Cover?

Do you ever worry about bed bugs ruining your sleep? Have you heard horror stories about bed bugs infesting mattresses and causing itchy, uncomfortable nights?

If so, then you’re probably wondering how long these pesky pests can live inside a mattress cover. The answer isn’t as simple as you might think. Let’s take a look at the facts.

The Lifespan of Bed Bugs in a Mattress Cover

When it comes to bed bugs and mattress covers, there are several factors that come into play. First, the temperature of the room plays an important role in determining how long bed bugs can survive.

Bed bugs are cold-blooded creatures and need warm temperatures to thrive. If the environment is too cold or too hot, they won’t last very long.

This means that if your bedroom is typically cool or you keep your mattress cover unzipped, then it’s unlikely that bed bugs will be able to survive for more than a few days.

On the other hand, if the environment is warm and comfortable (around 70-80°F) and your mattress cover is zipped up tight, then bed bugs can live for up to an entire year!

This is because they have access to plenty of food sources (namely human blood) and are protected from any natural predators (such as birds or spiders).

Additionally, since their movement is restricted in such a tightly-knit environment, most of them will die off within 15 minutes – so don’t wait too long before taking action!

Cleaning Tips & Tricks

Luckily, there are several preventative measures that you can take to reduce the likelihood of bed bug infestations in your home.

Most importantly, regular cleaning (especially vacuuming) can help keep these pests away by removing potential food sources such as dust mites and dead skin cells.

Additionally, checking your mattress periodically for signs of activity (such as small black dots or reddish stains) can alert you to potential problems before they become unmanageable.

Finally, always remember to zip up your mattress cover after use!


Bedbugs have been known to live up to 1 year inside a tightly sealed mattress cover due to its warmth and plentiful food sources; however, they generally die off within 15 minutes when exposed to air due to lack of oxygen and predation from other creatures like birds or spiders.

It’s important for homeowners to practice good hygiene habits such as regular cleaning and inspections for signs of activity in order to reduce the chances of an infestation occurring in their homes.

Moreover making sure that all beds are kept zipped up tight will also help ensure that any potential intruders don’t get comfortable enough to set up shop long-term!
