DUBUQUE – Pest control companies are reporting an increase in the number of bedbug cases in eastern Iowa homes.

The bugs don’t carry diseases but can cause painful bites, the Telegraph Herald reports. They often come out to feed at night and hide during the day in the crevices of mattresses and furniture.

Jeff Voss of Voss Pest Control said the business already has surpassed the total number of bedbug treatments they completed in 2014. Voss said they have done less than 100 treatments so far this year, but that the figure is “snowballing.”

Operations manager Charles Jones for BedBug Chasers in Marion said the company is addressing more homes and businesses infested with bedbugs every year. The company has performed 25 heat treatments to rid homes in Dubuque and East Dubuque, Illinois, of the bedbug infestations in just the last month.
