Why pest problems spread so easily in Newburgh
Most of the city was built before 1930, and much of it went up as attached rowhouses on narrow lots. Party walls, shared basement crawl paths and chases for old gas and steam lines run from one house to the next. When a building on the block has mice or roaches, the neighbors usually find out within a season.
Newburgh also has a large number of buildings that sat empty for years. The city and the Newburgh Community Land Bank have been rehabbing them steadily, but a vacant structure with broken windows is a pigeon roost and a rat harborage until it is closed up, and renovation work disturbs whatever was living inside. If a house next door to you is being gutted, it is common to see rodent activity spike for a few weeks.
Then there is the river. Front Street restaurants, the docks and the storm drains that run downhill from Broadway give Norway rats food, water and travel routes. Rat burrows in back yards on the lower blocks of the East End are a regular find for local technicians, especially along fences and under sheds.
