Bed Bugs adjust very well to their environment, even if conditions are unfavorable. Adults can go more than a year without food and can spend the winter in unheated premises. Nymphs are almost as resistant. Bed Bugs are active at night when their hosts'humans'are inactive. However, if the premises are only occupied during the day, Bed Bugs won't hesitate to attack humans during that time. They leave traces of blood and excrement (dried blood) on pillows and sheets. In severe infestations, it is possible to detect an unpleasant and rather sweet smell.
In the early stages of infestation, Bed Bugs will be found in beds. If they multiply, they will spread to other dark areas such as behind baseboard heaters, under fraying wallpaper, on walls behind paintings, around door frames, in various items of furniture in the bedroom, and in other rooms of the house.
They move from one house to another in several ways:
- On infested individuals
- From neighboring apartments
- When furniture is moved
- When clothing is stored
- When people travel (suitcases)
