When is NYC pest season — and is it getting worse?
NYC pest complaint data from NYC 311 (Jan 2023–Jun 2026) shows a consistent summer peak and winter trough for rodent complaints, while insect/vermin complaints (UNSANITARY CONDITION — PESTS) follow a different seasonal arc — peaking in late summer and fall rather than early summer. Together, these two complaint streams reveal distinct seasonal behaviors for different pest categories, tracked continuously by the NYC Department of Health and Mental Hygiene and NYC Housing Preservation and Development.
