Downtown along North Street and Main Street is mixed-use. Restaurants on the ground floor and apartments above mean food, warmth and plumbing all stacked together, which is exactly what German roaches and mice want.
Up on Highland Avenue the houses are bigger and further apart. The trouble there is height and trim. Slate roofs, cornices and attic vents on three-story Victorians let bats and squirrels in at places nobody can reach without a tall ladder. A few of those houses have been converted into nursing homes, which adds a commercial wrinkle to who handles the work and how often it gets inspected.
Near SUNY Orange and the old Horton Hospital building, now Touro's medical school, there are plenty of rentals with turnover every semester. Moving day is when roaches, and silverfish tucked into old cardboard boxes, come along for the ride. Landlords who have the units checked between tenants save themselves a lot of trouble.
Toward the city line, the 1950s and 1960s ranches and capes look a lot more like the Town of Wallkill next door. Fewer shared walls, more lawn. Calls here lean toward ants, spiders, skunks under the stoop and mice coming in through the garage door seal. Homes backing onto Fancher-Davidge Park or Hillside Cemetery get more wildlife than the blocks around them.
