Spiders in New Mexico: what the public record shows

Before you compare quotes, it helps to know which spiders actually live in New Mexico, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.

Spiders of medical concern in New Mexico

NMSU's arid-Southwest spider project names two groups: Latrodectus widows and Loxosceles violin spiders.

Several species of violin spiders, Loxosceles spp., are also quite toxic. These include L. arizonica, L. deserta, L. apachea, L. blanda and (in eastern New Mexico and by introduction in various parts of the Southwest) L. reclusa
Which recluse species occur here

New Mexico's native recluses are desert species; the true brown recluse reaches only the eastern edge of the state.

When spiders are busiest in New Mexico

Widows and violin spiders shelter year-round in seldom-disturbed places; NMSU advises never placing a hand where you cannot see or into a tangled web.

NMSU: 'Fortunately, black widows are very shy and very few bites are recorded for the number of spiders occurring in the region,' and 'violin spiders are not especially aggressive and may live in numbers in a house without a bite occurring.' The brown recluse proper (L. reclusa) is reported in eastern New Mexico and established around Roswell; the rest of the state's recluses are native desert species.

For context, nationally

  • Throughout North America, but are most common in the southern and western United States — Black widow distribution. CDC/NIOSH
  • In the midwestern and southern United States — Brown recluse distribution. CDC/NIOSH
