A Dense, Older Core
Downtown sits on some of the oldest blocks in the village, close to the original railroad grid that shaped how Downers Grove grew. Buildings here mix ground floor retail and restaurants with condos and apartments above, and many structures carry decades of age. That combination brings its own pest pattern.
Restaurants and food businesses draw cockroaches, mice and flies if drains, storage areas and trash are not managed carefully, and pests from one unit can move into the apartments above or next door.
Condos and apartments above shops can see cockroaches, bed bugs and mice travel through shared walls, floors and utility chases, so a problem in one unit rarely stays contained to that unit.
Older buildings have more gaps around old window frames, transoms, utility penetrations and foundation joints, which is exactly what ants, spiders and mice look for.
