Byron e-mails: “Today every student on my team at school received a letter about inspectors spotting a bed bug in one of our classrooms. They said they will not issue a pest control spray because it is just a small case of one bed bug… I don’t want to go to school until the pests are clear, but sadly that’s part of my life and I have to go. What can I do to keep these disgusting creatures out of my home?!”
Anna writes: “…My school has a bed bug infestation because of what I found last week in class. I was at my table when I found a bedbug crawling on the desk. I immediately killed it and blood came out of it. It was small so there must be more. What can I do? I already advised some teachers and students as well as my principal but (they) have not done anything? What should I do?”
Dear Byron and Anna,
Your school administrators are correct advising parents to be on the lookout for bed bugs that may hitch a ride to school. However, the sighting of one bed bug does not mean that there is an infestation at your schools. Chances are that the bed bug(s) hitchhiked in from a student or staff member that either has bed bugs at home, or picked them up on the way to school.
Your administrators were being cautious about applying chemicals in a school that may not have an infestation. Although it is important to keep schools free of pests, many pesticides are inherently toxic and may have potential health risks, especially when used in the vicinity of children. Because humans and pests depend on the same food chain, it is not surprising that the use of chemicals that are intended to kill pests comes with some unknown risks to people. Sprayed pesticides may become airborne and settle on toys, desks, counters, shades and walls. Children and staff may breathe in contaminated air or touch contaminated surfaces and unknowingly expose themselves to invisible residues. Accumulations of pesticides can linger for months beyond the initial application. The proper course of action is to investigate the extent of the pest problem and then use the least toxic steps to mitigate the problem, such as barriers, sanitation and maintenance prior to pesticide applications, if needed. This is called Integrated Pest Management (IPM) which is mandated for schools in many states and practiced in New York City schools. Vacuuming, steam cleaning, the use of hot dryers, plastic boxes for storage, and removing clutter where pests may harbor is the preferred action for single bed bug sightings in schools.
To prevent the spread of bed bugs at some affected schools, students and teachers put their coats and bookbags into individual plastic containers and bags. Never throw your coat on the floor – you have no idea what else may be on the floor that you cannot easily see. Try to bring as little back and forth from home to school. When you get home, store your coat and backpack in a plastic bin, just in case something crawled in. When you get home empty your book bag on a flat surface like your kitchen table or a desk and do your homework, then pack up your bookbag and place it in the plastic box overnight. Never throw your bookbag on a bed or couch. As a prevention, bookbags and jackets should be treated in a hot drier once a week, especially if your school has had a recent bed bug sighting.
Schools should also educate all staff and parents about bed bugs, their school IPM policy and bed bug action plans – before there is an incident. This proactive approach will help to lessen bed bug hysteria, when an incident does occur. For more information and materials, go to http://www.epa.gov/bedbugs/.
