Alliance City School District said on Thursday it used a certified pest control company to treat the entire high school for bed bugs and will treat all the buses Thursday night.
Alliance closed its high school during the inspection and treatment, the district said.
"The health and safety of our students is our top priority. After today's inspection and treatment, it has again been confirmed that the district does not have an infection," Superintendent Jeffrey Talbert said "If additional bugs are found after today's treatment, it will be because they are being brought in from an outside source, not because they are residing in the high school. We will continue to be diligent in identifying and preventing further bed bugs in the building."
The district asked parents to watch out for bed bugs at home. Look for bite marks on the body, bed bugs' exoskeletons, bed bugs in the folds of mattresses and sheets, blood spots, or a sweet musty odor. Backpacks, lunch boxes and other items that travel back and forth to school should be inspected daily.
The district said parents should notify the school if they suspect an issue with bed bugs at home.
It is currently unknown if the high school will reopen on Friday.
