General Facts & Myths About Bed Bugs

Bed Bug Myth #2 – Eggs and shed skins are a sign of bed bug infestation?

Mostly False. Bed bug’s eggs are distinctive but it’s still possible to not recognize them or mistake them with those of other insects. Skin sheds are easier to define but only if they are whole. The only true sign that there is a bed bug infestation is seeing living bed bugs.

Bed Bug Myth #3 – Bed bugs live in clothes?!

True. Usually, these are faecal traces. Bed bugs may leave such marks anywhere in the room but especially on the sheets. After all, they feed quite often and multiply very fast.

Bed Bug Myth #5 – Bed Bugs Can Survive a Whole Year Without Food

False mostly. This is a very popular bed bug myth you’ll see anywhere on the web. The truth is, a bed bug is able to survive that long only if its adult and spends the whole 1 year at a temperature of 10 °C, which is kind of impossible. In a room with the most favourable temperature for the insects, bed bugs will survive for only 100 days without food.

Bed Bug Myth #6 – It’s a Good Idea to Throw a Mattress if it’s Infested?

Bed Bug Myth #7 – Bed Bugs are Scared of Light!?

Bed Bug Myth #8 – Vacuuming and Decluttering Helps to Avoid Bed Bug Infestation

Bed Bug Myth #9 – Bed Bugs Live Only in Big Cities.

Wrong. According to the “Bed Bugs in America” survey done by NPMA, the creatures were spotted in all 50 states of the country. In the UK, they are present everywhere but mostly in London.


Bed Bug Myth #10 – Bed Bugs Can Survive at -50°C.

Nope. At this temperature, the species dies pretty fast. According to Science News, this has been tried already. Scientists have already experimented on bed bugs and low temperatures. It was found that the lowest temperature was -25°C at which only an egg would survive but not an adult bug.

Bed Bug Myth #11 – Bed Bugs Have Wings and Fly.

Hilarious. This is not true at all. Still, there are many people who ask “Can bed bugs fly?”. Bed bugs are unable to fly, they can’t even jump (this is what ticks do). The only way for bed bugs to move is by crawling. They still have wings, also known as hemlytral pads but there are no hind wins.

Bed Bug Myth #12 – You Can Find Bed Bugs in Kitchen Appliances?!

True. As we’ve already mentioned, bed bugs are attracted by darkness and heat, an oven that’s been recently turned off is such a thing. Don’t be stressed if you spot a bed bug crawling out of a kitchen appliance, try to identify if it’s really a bed bug instead.

Bed Bug Myth #13 – Keeping The Suitcase Away Helps?

Fact #1 – Bed Bugs Can Live Anywhere In Your Home. Not Just in the Mattress.

There aren’t multiple opinions on this, so it’s more like a fact. Bed bugs may live in any place that is dark and provides a form of shelter. That would be inside cracks in the walls or furniture and in your luggage no matter if it’s packed or not.

Bed Bug Fact #2 – Adults may reach a size of over 7mm in length.

Bed Bug Fact #3 – The most favourable temperatures for bed bugs are 70-80F (21 – 26 °C).

Bed bugs will reproduce best at this temperature. It’s also important to know that a temperature of 56°C (132F) or more will kill a bed bug at any life stage. This is the exact temperature at which a room is heated during a bed bug heat treatment, which is one of the most effective ways of bed bugs extermination.

Bed Bug Fact #4 – Bed Bugs Are Predictable.

That’s true only when it comes to their feeding habits. A typical bed bug would prefer not to spend more than 10 minutes on its victim. Another typical feature is that this insect would live as near as possible to the victim. That’s why bed bugs usually live under the mattress – it’s simply very close to the sleeping person.

Bed Bug Myth #14 – Bed Bug Bites Are not Dangerous
