As we published an article about it before, bed bug bites will cause some health problems including itching, red spots, blisters and other secondary infections:

What u mean by contagious?

There may be two different meaning for the word “contagious”. One is about carrying diseases from one person to another and the second one is about moving from one place to another.

If you are curious about if bed bugs transmit some diseases from person to person, such an infectious case hasn’t been documented by any health organizations yet.

However, some studies claim that some diseases like yellow fever, HIV or plague can be transmitted by bed bugs, there is no any documented case in US.

But if you are curious about if bed bugs can move from one place to another or from one person to another; yes, it’s very possible.

How bed bugs move from one place to another?

Bed bugs can’t jump or fly so, they need a carrier to move away. It’s not difficult to move around in a house for bed bugs; but when it’s about travelling long distances, they can’t do it by themselves.

Some of their travel items are below:

  • Clothes
  • Furniture
  • Beds
  • Old staff

Bed bugs are contagious at school or work

What makes them very contagious at work or school is that environmental control in such places are very difficult.

You can check every single person entering the school or office. You can’t control their bags, clothes or other personal staff.

So, when someone has bed bugs in personal staff like clothes or bag, bed bugs can move from one person to another one easily. Because they are so little in size and although they are visible to human eye, it’s difficult to see them while they are moving around.

How to prevent bed bug invasion at school?

However, it’s difficult to fight with bed bugs at school, there are some ways that can prevent bed bug invasion.

These steps can be taken by parents in such a deal:

  • Children infected by bed bugs must stay at home
  • All staff in the school must be checked carefully
  • There shouldn’t be unused clothes, boots or bags around
  • A professional pest control expert must be hired
  • Floor and hard surfaces must be cleaned with hot soapy water

Are bed bugs contagious to dogs or cats?

As I told above, bed bugs feed on mammalians by their bloods.  So, they prefer to host in cracks or holes which are near to their food sources.

If there are bed bugs at home, they will probably try to feed on your pets like dogs or cats. But you must remember that bed bugs will always prefer human as the main and first food source.

This means that bed bugs can spread on your dogs or cats but, if there are human around and bed bugs can reach them, they won’t prefer feeding on pets.

What’s important about pets is that they are very good hiding places for bed bugs and a dog’s or cat’s hairy skin will become an ideal host for bed bugs.
