Pest ControlQuestion 189 of 319
Under standard exclusion practice, the maximum gap allowed under an exterior door of a food facility is approximately:
a.1/2 inch is fine if the door looks closed
b.There is no recommended limit
c.1/4 inch (sealed by a door sweep)
d.1 inch
Explanation
Exterior doors should fit tightly with no more than about 1/4 inch of gap underneath; this is enforced with a door sweep or threshold. A mouse can squeeze through a gap of about 1/4 inch, so anything larger creates a clear entry path. Exterior doors must also be self-closing.
