Stay tuned to uncover the hidden world of the red house spider and discover how you can protect your living space from their unwelcome presence. The red house spider is worldwide in distribution, but is reported to occur primarily in the states of Texas, Florida, and California. The appearance of spiders, egg sacs, and the remnants of insect prey are signs of an infestation. The Red House Spider is a dangerous spider that should be avoided. They are found in Australia, and their bites can cause serious health problems. However, they are not poisonous, unlike the brown recluse bite, which is highly poisonous.
Yellow Sac Spider
They are not aggressive and will typically only bite humans if they feel threatened. This article is a guide to identifying the most common types of red spiders. Descriptions and pictures of the eight-legged creatures will help you recognize the individual spider species.
Yellow sac spider
The tropical shiny red spider has the appearance of a kite from head-on. As with most spider species, the female is the largest and most colorful. Like all red spiders, red woodlouse spiders are venomous and can bite. However, their venom isn’t necrotic, and the punctured skin will usually be red, itchy, and painful. Red spider mites are tiny destructive pests with a red body and minuscule white legs. Belonging to the spider class Arachnida, the red mite has eight legs and spins webs on plants.

Common prey for the Red House Spider includes ants, flies, beetles, and other small critters. Outdoors, it’s common to find these spiders hiding under the lips of plant pots, in sheds, or in the cracks and crevices of various other locations. This species of spider has spread all throughout the world, but it’s most common in California, Texas, Florida and Australia. The red thorn spiny orb-weaver spider measures 0.31” to 0.39” (8 to 10 mm) at its widest part (excluding the two long thorny projections). While they’re usually busy with their bug snacks, they might give a small bite if they’re startled or feel trapped. A bulbous abdomen is characteristic of most spiders of this wider category.
This is where they have access to sugary foods such as fruits. Further differences are also seen between the sexes as the male might not have a red abdomen but a black abdomen. This species moves like ants but it can move like spiders as well. They build spider webs on top of ground-level leaves as shelter and to hide. Spiders of this genus might mimic ants but they still create spider webs. Spiders of this genus have the same color and the same shape as the Asian Weaver ants which doesn’t make them appear as spiders at all.
For me, there is nothing quite like the joy and love that a furry friend can bring into our lives. A biotechnologist by profession and a passionate pest researcher. While it is present worldwide, the Red House Spider has a preference for warmer climates. Despite this preference, it’s often found in cooler places within homes or in shaded areas outdoors.
The bright red or deep-orange body, four eyes on top of its head, and hairy gray legs distinguish Whitman’s jumping spider. Red house spiders belong to the comb-footed spider family and are characterized by the comb-like spines on their legs. Their webs are usually messy and tangled, providing protection from predators. These spiders spend most of their time waiting for prey to get trapped in their webs, which take up almost half of their time.

Spiders of this genus have a red cephalothorax and red legs. Some of the most common red spiders are found in the house and around the house as many species are tied to manmade buildings. Most red spiders that bite cannot pierce the human skin with their short mouthparts. They can have a painful bite, inject venom, or even cause infections.

The body of the cardinal jumping spider is hairy, and its legs are black or grayish-black. It features two large middle eyes in addition to a row of eyes. Sac spiders vary drastically in coloring and are sometimes confused with other spiders due to shades ranging from yellow to brown to green. It's a good idea to keep your distance from these spiders, as their venom contains cytotoxin and has been shown to be toxic to humans. Use a vacuum or broom to clean them up or hire a local IPM specialist.
It is important to note that severe reactions to red house spider bites are rare. However, individuals who are allergic or sensitive to spider venom may experience more severe symptoms and should seek medical attention if bitten. If you suspect a red house spider bite, it is advisable to clean the area with mild soap and water and apply a cold compress to alleviate any discomfort. Red house spiders are formidable predators, preying on insects that get caught in their webs. They use their venom to immobilize their prey, allowing them to feed at their leisure. These spiders are known for their patience, waiting motionlessly for unsuspecting insects to become ensnared in their intricately spun traps.
Look for their large, orb-shaped web near lights, often constructed on buildings or other man-made objects. During the day, there is often a silken retreat that they retreat to for safety. Look for a thick zigzag of silk in the center of the web called the stabilimentum (seen below). Some scientists think the zigzag mark helps to deter larger predators from running into it and destroying it. But other researchers think the stabilimentum reflects sunlight, which helps attract insects to the web. Before we begin, note that the list below is just a fraction of the overall number of spiders found in California.
An orange-red abdomen is characteristic as are red front legs. Such small parasitic spiders are often tolerated by the host species due to their vivid coloring and their movements on the spider web. A round dome-shaped abdomen is characteristic of the species. Its white stripes help it distinguish itself from other orbweavers.
The type of web the spider creates is another way to distinguish its species. Red orb spiders create symmetrical circular webs, while red house spiders create messy, irregular webs. They’re not aggressive and won’t bite unless you threaten them or try to harm them. Observing their web-building behaviors and movements can offer interesting insights into the natural world, making them fascinating to observe.
The front red legs of the species are best seen in the mating process. This species is always connected to the spider web through a single silk line and hang just above the ground waiting for prey to get trapped. These movements can attract flies into the spider web of the host species. These small spiders then steal any insects that get caught up in the spider web of the host spider.
A better dance increases the likelihood that the females will want to mate with the male. Males must be VERY careful when approaching the female; if the dance isn’t good enough, they risk being eaten. If you bother a Spotted Orbweaver, it will bite you in self-defense.
