Vermont state officials say they are continuing to investigate the possible misuse of a pesticide in the Rutland area by a pest control company.
The Agency of Agriculture suspended the license of AAA Accredited Pest Control company last month.
The company is suspected of using a chemical to treat bugs that’s been prohibited for indoor use since 2001.
The state has sent letters to 150 residences that were sprayed with various pesticides seeking to collect samples for testing. That's in addition to the 61 homes already tested.
The Health Department says symptoms of exposure to the chemical chlorpyrifos include runny nose, tearing, nausea, vomiting and diarrhea. Long-term symptoms can include memory or sleep problems.
The owner of the company did not immediately return a phone call seeking comment.
