Contractor skilled at rodent exclusion?

[kathmandu]

Can anyone recommend a contractor in the greater Camberville area who's good at rodent exclusion? As in, identifying where and how they're getting in, then systematically blocking those entrances so the rodents *stop* getting in.

This is for a 10-residential-unit building, brick and cement block outside, drywall inside. So someone who can handle a project larger than a single-family home. (It's a condo complex; the condo committee does not have any existing connections for that kind of work.)
