Bugs and spiders in Nebraska

Asian lady beetles are the most-recorded species in Nebraska, with the American dog tick close behind, followed by bold and tan jumping spiders. The state has a mix of Get-advice species that depends on where you are: the brown recluse and western black widow are both established, and the Rocky Mountain wood tick reaches the western edge. A northern black widow shows up in records but is not known to live here.

What to watch for in Nebraska

The American dog tick and lone star tick are both established and heavily recorded, and the blacklegged tick is established but patchy, with only a few counties involved. All can carry disease. The Rocky Mountain wood tick is established along the western edge of the state and can spread Rocky Mountain spotted fever, Colorado tick fever and tularemia. The brown dog tick feeds mainly on dogs.

The brown recluse is established, though only part of Nebraska lies in its range, in the southeast. The western black widow is established too, and a bite from an adult female can cause severe muscle pain. Northern black widow records exist, but it is not known to live here, and those records are more likely western black widows, which look almost identical. After a worrying bite, get medical advice or call Poison Help (1-800-222-1222).

Through the year

Spring
American dog ticks and eastern carpenter bees become active in April, and Rocky Mountain wood ticks appear in the west after snowmelt.
Summer
European paper wasps and yellowjackets work around the outside of the house, and yellow garden spiders build webs by doors and windows.
Fall
Asian lady beetles, boxelder bugs, brown marmorated stink bugs and western conifer seed bugs move into houses, and spotted orbweavers are most noticeable.
Winter
The usual indoor finds are house centipedes and Indianmeal moths, with a few lady beetles on warm days.

Seen now and then

Recorded a few times; often brought in on plants, firewood or luggage.

Recorded, not established

Range maps don't place these here, but people have recorded them. Usually hitchhikers.

Lists come from research-grade iNaturalist sightings (Nebraska: 103,912 arthropod records) and, for dangerous species, published range maps. A species with few records may be a hitchhiker. Counts pulled Oct 18, 2026.
