Can bed bugs live outside in heat or cold?

Bed bugs do not like hot, because very high temperature will cause them die because of dehydration. They will start dying after 113°F when they are exposed to this temperature for a few hours. Above this temperature, they will die sooner.

Bed bugs also do not like cold. But they can easily survive up to 45°F. Under this temperature, they will slog on living. Under extreme colds like 0°F, they will die.

So, will bed bugs survive outside in summer or winter? Probably, yes.

Even if you have a hot summer with high temperatures like 113°F, they will still be able to hide on cooler and darker places to keep their body warm stabile.

And if you do not have a very cold winter with a lot of snow and degrees under 0°F, they will have a chance to survive.

Can bed bugs live outside in grass?

This is possible too. But it won’t be a good choice for bed bugs. They need feeding to keep living and grass won’t offer them more options.

If you found a bed bug in grass, it’s most likely to move from somewhere to another one. Grass is not an option to host for bud bugs but only a way to their hosts or food sources.

Can bed bugs live outside in wood?

Woods are good places to hide for bed bugs just like furniture or beds. So, you can find them on woods.

But there is still the same problem here. How can a bed bug living in wood keep feeding? If woods are close to those places where you sleep or spend a lot of time outside, then bed bugs can live in woods too.

Can bed bugs live outside in yard?

No, open places like yards are not option for bed bugs. They love and need hiding from people and yards with no cracks or holes won’t help them on this.

If you find any bed bugs in yard, they are walkers from somewhere to another one too.


Can bed bugs live outside? Yes, they can. But when you come across a bed bug in your garden, yard or grass, what you must be worried about is the possibility of bed bugs being inside your home.

If you have bed bugs in your home and trying to find them all, you must check your cars. Bed bugs can be transmitted by yourself in your clothes to your car and after they settle in your car, they will quickly multiply.

Searching your garden and outside your home after a bed bug invasion will be a good precaution to get rid of bed bugs permanently.
