To completely rid your home of bed bugs, hiring a professional exterminator is recommended. Most states require their insect pros to be licensed, but be sure to ask how long any contractor or company has been in business and if they've ever dealt with a bed bug infestation. Experience with ants, termites or beetles isn't the same — bed bugs present a unique challenge for any exterminator. Also, look for a company that uses the integrated pest management (IPM) approach. Instead of relying entirely on pesticides or chemicals, IPM uses a combination of chemical measures, preventive measures, and sanitation to improve efficacy and limit environmental impact.
