In Chelsea, Massachusetts, school officials expect to keep Chelsea High School closed for at least two days because of a "nasty" fly infestation. The school was also closed for two days last week out of concern for students' health. Contractors are cutting through a concrete floor at the school in order to reach several damaged pipes that are believed to be the source of the pests. Once the pipes and floor are restored, reports say that the school will be thoroughly cleaned.
The cracks in the four pipes at issue were discovered using video technology last week. It was early this month that flies were found in the school's kitchen. According to New England Cable News, student Antonio Falcon said that "nasty" flies were infesting not only the cafeteria, but also the hallways and gymnasium. Windowsills, Falcon said, were windowsills “were packed with dead flies.”
School Superintendent Dr. Mary Bourque stated in a letter to parents, "On December 5, 2016 our Facilities Management Department began receiving complaints of a few flies in the kitchen area. Our drain cleaning contractor was immediately called in to clean out all drains and grease traps as a possible source of the problem." She said that there is a possibility that the school will remain closed this Wednesday.
In a post on the AskEntomologists
website, it is recommended that before applying pesticides that the species of the flies or other harmful insects should be identified. A general cleanup of the affected facility is recommended, especially in the case of fly infestations.
