Small black spots around mattress seams, headboards or bed frames can be an early sign of bed bug activity.
Bed bugs often hide close to where people sleep, and catching the signs early can help prevent the problem from spreading throughout the home.
If you notice suspicious marks, bites, shed skins or live activity, contact Thermokill for professional bed bug treatment in Toronto and the GTA.
