Bed bugs feed on only blood. They are blood-fed creatures and main food source of bed bugs are mammalians.

So, they feed on bats and human primarily. They can feed on birds or cats or dogs too, but they prefer to feed on these animals only when there are not any human hosts around.

This means that their favorite food is us, human!

After taking a glance at some studies, the answer will be around 1 YEAR!

What does 1 year mean?

This means that it’s difficult to get rid of bed bugs. you may have no bites for months or you may haven’t seen them for a long time, but they can still be there, near you.

Even after a house left empty for more than a year, new movers can face the same bed bug problem as the previous hosts had.

You must understand that bed bugs do not host on human or other mammalians, unlike fleas. Their hosts are cracks, holes, furniture, clothes or other staff which are near to their food sources.

So, bed bugs do not need to host on human for surviving. What they need is only a secure place close to their feeding sources.

Conclusion

Yes, bed bugs need to feed for surviving too. But unlike most alive, they can deal with hunger for a very long time.

If conditions like temperature or hiding possibilities are suitable for them, bed bugs can live for more than 1 year without feeding.

This doesn’t mean every single bed bug will survive for more than a year without surviving. Environmental conditions will of course, change their resistance. But you must be ready to the worst scenario to get rid of them.

So if you had bed bug problem once and you can’t see them around for a long time, do not relax to forget them.

Always be skeptical and keep searching them around on occasion.
