"The first thing you're gonna want to do is make sure your room is dark. Turn off lights, close any shades, and use the flashlight on your phone," Halee explained demonstrating in a short video clip.
Whether you have fitted sheets or a mattress pad, you'll want to check in the dark corners, under the bed.
"They usually like to hang out in the corners and the creases," she said.
"The reason you should check your bed with the lights off is because bed bugs are actually nocturnal, so they're more likely to be out and about looking for their prey," she explained.
She also said that travellers should avoid unpacking until they've run a thorough check, as bedbugs are notoriously bad for stowing away in spare clothes and luggage.
The hotel worker says that there are a couple of other places she checks for cleanliness out of habit.
The minibar fridge, curtains and even the ironing board are good places to see how thorough housekeeping staff are.
Hand prints on the wall near the bed head are never a good sign.
"I always run my finger over the headboard to check for dust," she says.
If those are spotless you can be pretty sure the cleaning is on top form.
"Even if you don't see bugs, make sure you look for spots like blood spots cause that's not a good sign either."
