Healthcare facilities should develop a policy that defines what actions will be taken when fire ants are seen, according to an article on the Pest Control Technology website. Policies should include removing patients from the area and notifying pest control provider about ant problems.
Facilities should have a logbook on site for staff to record pest sightings. Make sure to indicate that action has been taken on all items listed in the logbook.
Fire ant treatment should be extended beyond just the immediate perimeter of the building. The Mississippi Department of Health states that 25 to 50 feet around the building is a critical zone requiring regular inspection for ant activity.
In an ideal world the entire lawn would be treated, but even a treated zone around the perimeter of a large building can help.
