The main stereotype of a bed bug problem must be that you are a poor housekeeper or you have poor hygiene to have an infestation, this is simply untrue. Bed bugs have adapted well to live with humans and invasions into your personal space have no bearing on your homes current condition.
These blood suckers are extremely good hitchhikers and can easily travel from place to place in human belongings such as luggage, folded clothes, bedding, furniture, and boxes and can also hide in discarded furniture and electronics that people unwittingly bring into their homes.
Peak bed bug season is typically between June and October, when Canadian weather is warmest and the insects reproduce fastest.
