It may be very difficult to find them at first. Don’t be fooled though. You can see them…eventually. As the population multiplies they are easier to find. These nasty little bloodsuckers don’t like coming out during the day, just like vampires.
As the infestation grows it is not only easier to see them during the day, they begin leaving their mark on everything. You may notice a dark line, particularly in the crevices of your mattress. If you have light-colored furniture you can also see the dark lines they leave behind during their travels.
If you think you have an infestation you can test your suspicions by sleeping on a white sheet. In the morning, check the sheet for little dots of blood. This is not any blood; it’s your blood. These parasites actually inject a secretion into your skin before feeding and this can cause an allergic reaction in some people.
