Scorpions in Las Vegas 2025

The desert climate of Las Vegas is predisposed to the invasion of various insect pests, such as spiders and scorpions. In recent years, in spring and autumn, the city has been overtaken by a large number of scorpions. At this time of year, they can be everywhere in Vegas—in private yards, in gardens, on palm trees, and in bushes.

More About Scorpions

It is easy to identify scorpions by their appearance: eight legs, large claws, and armed with stinging tails. There are some poisonous species. They usually appear at night, as they are prey to birds and rats. In the daylight, they hide. Scorpions become fluorescent under ultraviolet light. In this way, you can catch scorpions at night in Vegas.

Bark Scorpions

The valley of Las Vegas is home to about 23 species of scorpions, with the Bark Scorpion being the most concerning. Known as the Arizona Bark Scorpion, it is commonly found in Las Vegas and Clark County, Nevada, often residing on palms and shrubs. This scorpion, which has a venomous sting, primarily feeds on smaller pests and insects. Averaging 2.7 to 3.1 inches in length, the Arizona Bark Scorpion is characterized by horizontal lines on its mesosoma and a slender tail ending in a sharply curved stinger. Its small size and agility allow it to conceal itself in its surroundings easily.

Best Time to Observe

The warm desert climate of Las Vegas offers an ideal environment for scorpions to thrive. With hot summers extending from March through fall, these months represent the peak activity period for scorpions. Spring and autumn are also the mating season of scorpions. Its peaks can vary as it depends on the species and the region they live in. However, they do not vanish during colder months or warm winters. Scorpions adapt to lower temperatures by finding shelter under rocks, within crevices along walls, or even inside houses.

Safety Rules

Observing scorpions might seem like an interesting experience and quite a fun adventure for insect enthusiasts. It is still a really dangerous activity that shouldn't be done without specific safety rules and restrictions. To prevent scorpion stings, always wear shoes. In regions like Las Vegas, where scorpions are more common, it’s important to respond quickly and with care when encountering one. The severity of a scorpion sting can vary by species, with those in the Southwest, including Las Vegas, sometimes delivering venomous stings that may require immediate medical attention. If you come across a scorpion, remain calm; panicking can provoke a defensive reaction. Indoors, use a sharp object to gently guide the scorpion into a lidded container. Always wear gloves and long sleeves when handling scorpions or cleaning areas where they might be present.
