A cockroach infestation in Cambridge usually traces back to a specific conducive condition: a leaking pipe, a gap behind a stove, cluttered storage near food. Dense triple-decker and multi-family housing dominates in the urban core, alongside single-family suburban homes further out, most with basements. Once established, an infestation spreads unit-to-unit in multi-family buildings through shared walls and plumbing chases.
We start with an inspection to identify the species and the source — sanitation issue, moisture problem, or entry point. Treatment centers on gel bait placed in cracks, voids, and under appliances, not broadcast spraying, since German cockroaches in particular have developed resistance to many surface sprays. A follow-up visit confirms the bait is working and the population is dropping.
