No one reason explains the increase in bed bug infestations. Bed bugs are back, regardless of how they got here.

The rise has been referred to at "the perfect storm." Most likely it is a combination of all these factors that resulted in the situation we are dealing with today:

• Change in pesticide availability
• Change in pesticide use patterns
• More travel/mobility of people
• More infested locations
• Pesticide resistance
• Lack of preparedness of society in general
