 ‘Hordes’ of Tarantulas Spotted Across Southern Missouri as Mating Season Begins

Missouri residents in the southern and central parts of the state may want to watch their step — large tarantulas are on the move. The state’s only native species, the Texas brown tarantula (Aphonopelma hentzi), is emerging in noticeable numbers as annual mating season begins, creating what some are calling “hordes” of spiders crossing roads, trails, and rocky terrain.

These spiders, which can span up to four inches across, typically remain hidden underground or in crevices for most of the year. But in late summer, mature males begin roaming during warm evenings in search of females — sometimes covering surprising distances and triggering sightings in residential areas, roadsides, and parks.

Despite their size and fearsome reputation, experts stress that these tarantulas are not dangerous to humans. They are shy, nonaggressive, and only bite if provoked — and even then, the bite is no worse than a bee sting. Wildlife authorities urge the public not to disturb them and to let them continue their short-lived journey.

Reports of tarantula sightings have recently surfaced across southern Missouri, including areas near the Ozarks, glades, and prairie edges. According to local conservation groups, this is part of a natural cycle, not an infestation. The Missouri Department of Conservation confirms that tarantulas are a normal part of the state’s ecosystem, particularly in dry, rocky habitats.

Residents are encouraged to stay calm, observe from a distance, and avoid harming the spiders. Most of the roaming males will die within months, while females — which remain hidden — can live for decades.
