Consider non-chemical methods of killing bed bugs -
1. Heat treatment using a clothes dryer on high heat, black plastic bags in the sun or a hot, closed car.
2. Cold treatment can be successful in the home environment if the freezer is set to 0o F. You must leave the items in the freezer at that temperature for four days. Always use a thermometer to check the temperature, since home freezers are not always set to 0o.
3. Steam cleaners (wet or dry) can penetrate into cracks and fabrics to treat carpets, baseboards, bed frames, and other furniture. Steam temperature must be at least 130 F, but should not have a forceful airflow (use diffuser) or it may cause bed bugs to scatter.
Consider pesticides (be extremely careful with these methods, if does not know how to use take expert help)
1. Look for EPA-registered pesticides and Bed bugs must be listed on the label.
2. Use foggers (bug bombs) only with extreme care. Improper use can harm your health or cause a fire/explosion. Because foggers work with a broadcast spraying action, they should not be used as the sole source of bed bug control. The spray will not reach the cracks and crevices where bed bugs hide.
