Why is there infestation of bed bugs?

Bugs: Poor disinfection or cleansing or coming in contact with a carrier.

Cimex lectularius or: The bed bug is a parasite that is nocturnal. It can be transported on your clothing, luggage, second hand furniture etc. You can even get it using public transportation. It can go up to a year without feeding, so that allows it to just sit and wait until it catches a ride on something or someone. If you live in an apartment complex it may move from one unit to another. It is an insidious problem.
