What to watch for in Kansas

Kansas has four Get-advice spiders established. The brown recluse is heavily recorded, and the western, southern and northern black widows all live here, with the western the most recorded. Black widow bites can cause strong muscle pain and cramps, and some recluse bites heal slowly. If a bite worries you, get medical advice or call Poison Help (1-800-222-1222).

The lone star tick is the most recorded tick, then the American dog tick, and both are established. So is the blacklegged tick, though it is recorded far less often. All can carry disease, and lone star bites are linked to alpha-gal syndrome. The brown dog tick feeds mainly on dogs and can breed indoors. The Carolina wolf spider is rated Be careful rather than Get advice.

Through the year

Spring
Eastern carpenter bees get busy as the weather warms, and black carpenter ant swarmers can show up indoors in March through June.
Summer
Widows are seen most from late spring on, yellow garden spiders build webs near the house, and yellowjacket nests grow larger.
Fall
Carolina wolf spider males wander in late summer and fall, and Asian lady beetles, boxelder bugs and stink bugs move into houses.
Winter
Greenhouse camel crickets turn up in basements, house centipedes stay active indoors, and Indianmeal moths are most noticed between November and February.

Seen now and then

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

Lists come from research-grade iNaturalist sightings (Kansas: 155,367 arthropod records) and, for dangerous species, published range maps. A species with few records may be a hitchhiker. Counts pulled Oct 18, 2026.
