Some are vacuumed. Some are swept. Others are crushed, baited or trapped. The rest are kept out with caulk, window screens, door sweeps or, as a last resort, sprayed with chemicals.
In some schools, the spray comes first.
“We have a season that never stops,” said University of Arizona entomologist Dawn Gouge, about school pests in the state. “We have pest issues all year round.”
Many school districts have their schools sprayed with pesticides at least once a month to prevent or kill pests such as cockroaches and ants, Gouge said.
