Yes, chemical applications work best to remove bed bugs because the chemical provides a residue. When applied in cracks and crevices, the chemical is working long after the service technician has left. Other methods to remove bed bugs, such as heat, steam, and vacuuming are solid choices, but once the equipment is turned off, the bed bug removal application has ended. If just one bed bug is missed, you are back to square one. The key to successful bed bug removal is to get the appropriate chemical where the bed bug is. This means using the right tool, such as an Actisol unit.
