Common Spiders in Missouri: How to Identify Spiders of Missouri
Table of Contents
There are a lot of species of spiders found in Missouri, both in and outside of the home. Some are docile, like the common jumping spiders or the yellow garden spider, but other arachnids are very dangerous, like black widow spiders. Being able to properly identify whatever arachnids are in your area is crucial to ensure the safety of you and your loved ones. After all, to the untrained eye, all egg sacs and spiderlings can look the same. To help you navigate this, we’ll focus on the common spiders in Missouri that you are most likely to encounter.
At Titan Pest Pro, we understand the anxiety that spiders can cause, especially for families with kids and pets. That’s why we want to empower you with knowledge about Missouri’s most common species—what they look like, where they hide, and how to deal with them safely. Most importantly, we’ll explain why professional services are the best way to keep your home spider-free and your family safe.
According to the Missouri Department of Health, several hundred spider bite cases are reported in the state each year, with brown recluse bites being the most frequent cause of medically significant injuries. This is why it’s important to care about these insects in your area. Proper identification and management of them can be an issue of safety.
Beyond bites, spiders can become a nuisance when they build webs inside vents, basements, attics, and corners of your home. These webs can accumulate dust and debris, triggering allergies and making your living spaces uncomfortable. By learning about these spiders and their habits, you’ll be better equipped to prevent unwanted encounters and know when it’s time to call in the professionals.
As with any problem, understanding it is the first step towards success. Our team of experts has compiled a list of the common spiders in Missouri to help you stay informed and know which species you are dealing with.
The black widow is easily recognizable by its shiny, black body and the distinctive red hourglass shape on the underside of its round abdomen. Females are about 1.5 inches long, including their legs, while males are smaller and less venomous.
Habitat & Behavior: They prefer dark, undisturbed areas such as woodpiles, sheds, garages, crawl spaces, and even under outdoor furniture. Black widows are shy and rarely bite unless provoked or accidentally disturbed.
Bite & Risk: Their venom is neurotoxic, causing severe muscle cramps, nausea, and pain. While bites are rarely fatal, they require medical attention, especially for children, the elderly, or pets.
Known for its violin-shaped marking on its light to medium brown body, part of the cephalothorax, the brown recluse is about 0.75 to 1 inch long with long legs. Keep in mind that the “neck” of the violin points toward the rear.
Habitat & Behavior: They prefer warm, dry, and quiet places like closets, basements, attics, inside shoes or boxes, and under furniture. Brown recluses are nocturnal hunters and avoid humans when possible.
Bite & Risk: Their bite can cause necrosis, leading to painful skin ulcers and sometimes systemic symptoms. Prompt medical care is important, though not every bite results in severe injury.
These are large, hairy spiders ranging from 1 to 2 inches in body length, often mistaken for tarantulas due to their size and appearance.
Habitat & Behavior: Unlike web-builders, this species actively hunts its prey on the ground and doesn’t spin webs. You’ll find them in gardens, leaf litter, under rocks, and sometimes inside homes. They are fast runners and usually non-aggressive, but will bite if threatened.
Bite & Risk: Their bite can be painful, but is generally harmless to humans.
Orb weavers are named for their iconic circular webs. Their size varies widely, but many are around 1 inch long with colorful patterns ranging from yellow to brown or even bright hues.
Habitat & Behavior: Commonly found outdoors in gardens, around porch lights, and trees. They spin large, intricate webs overnight to catch flying insects. They are non-aggressive and rarely bite.
Bite & Risk: Generally harmless; their bite might cause mild irritation if at all.
These are small, brown, or gray spiders often found indoors. They build irregular, messy webs in corners, windowsills, basements, and closets.
Habitat & Behavior: They feed on household insects like flies and mosquitoes. Like other species, they prefer dark, undisturbed areas and are harmless to humans.
Bite & Risk: Their bite is mild and rarely noticeable.
Grass spiders are medium-sized, usually light brown with dark stripes running lengthwise on their bodies. They build funnel-shaped webs in grass, bushes, or low vegetation.
Habitat & Behavior: These spiders wait inside their funnels for prey. Found commonly in lawns, gardens, and fields. They do not pose a threat to humans.
Bite & Risk: Their bite is rare and only causes minor irritation.
AS the name implies, these have very long, thin legs and small, pale bodies. They often hang upside down in their messy, tangled webs.
Habitat & Behavior: You can usually find these spiders in basements, crawl spaces, sheds, and garages. They feed on other small insects and spiders, sometimes even preying on black widows.
Bite & Risk: They pose a very low threat to humans and rarely bite.
Yellow sac spiders are small and pale yellow, about 0.25 to 0.4 inches long. They build small silk sacs where they rest during the day.
Habitat & Behavior: Often found indoors on walls, ceilings, and windowsills. They hunt small insects and are active mainly at night.
Bite & Risk: Their bites can cause mild pain and localized irritation, but are generally not dangerous.
Fishing spiders are large, robust hunters, sometimes reaching 2 inches or more. They have mottled brown, gray, or greenish coloration, which helps them blend into watery environments.
Habitat & Behavior: True to their name, they are often found near ponds, lakes, streams, or wetlands. They can run across water surfaces and hunt aquatic insects and small fish.
Bite & Risk: They are generally not aggressive, and bites are rare; any bite usually causes only minor irritation.
Jumping spiders are small but charismatic, measuring about 0.25 to 0.5 inches. They have compact bodies, short legs, and are famous for their large, forward-facing eyes that give them excellent vision.
Habitat & Behavior: They are active hunters during the day, stalking prey rather than building webs. They can be found on walls, fences, windowsills, and garden plants. Their jumping ability allows them to pounce quickly on insects. Despite their bold appearance, jumping spiders are harmless and curious creatures.
Bite & Risk: They rarely bite humans. If they do, the bite might cause minor irritation similar to a mosquito bite.
Missouri is home to several insects that change their behaviors based on the season.
Understanding the seasonal patterns of the common spiders in Missouri can help you anticipate when they are most active and take preventative steps accordingly.
Below are the behaviors of spiders in relation to the seasons.
As temperatures rise and insects become more abundant, spiders emerge outdoors and build their webs to catch prey. Gardens, bushes, and the sides of buildings often become hotspots during these months. You’ll notice more webs in early morning dew or after a rain.
As the weather cools, many bugs seek warmth and shelter indoors. This is when indoor sightings increase. They look for cozy places like those where humans don’t typically go.
Most spiders either die off or enter hibernation outdoors. However, some adults survive indoors in heated buildings, especially those who made their homes inside before winter arrived.
It’s natural to want to get rid of spiders immediately, but you must take the proper safety measures to avoid injury. To do this:
Remember, most prefer to stay hidden and avoid humans. If you suspect you have black widows or brown recluses, it’s safer to contact professional pest control.
Many homeowners try to deal with spiders themselves using sprays, traps, or home remedies. Unfortunately, these methods often don’t solve the problem and can create new issues. When you do DIY control, you can may discover that:
