Is the spiny orb weaver spider poisonous

Orb weaver spiders, also known as garden spiders and banana spiders, are actually a group of spiders belonging to the family Araneidae. This family is one of the most diverse in the world and contains many different species of spiders. Common throughout the world, orb weavers can be quite intimidating in appearance; but the main question is are orb weaver spiders dangerous or not? Let’s take a closer look at the orb weaver, as well as some ways to prevent them.

Appearance

Orb weavers can grow to be quite large, ranging in size from 6 mm to 20 mm. Like all spiders, they have a cephalothorax (where their thorax and head are fused together), an abdomen, and 8 legs. They also have chelicera, which are fang-like mouthparts. They also have large abdomen that can actually overlap their thoraces, and hairy or spiny legs. Most nocturnal orb weavers are brown or gray in color while diurnal species are usually bright yellow or orange with their trademark black markings.

Habitat

Orb weavers are found throughout the world except Antarctica and the Arctic. In North America there are 180 species alone. These spiders usually inhabit locations that have an abundance of animals they can prey upon, along with structures that can support their webs. They are commonly found around night lights, tree branches, tall grass, fences, walls, bushes, and weeds.

Diet

Orb weavers feast on small insects like flies, beetles, wasps, moths, and mosquitoes. Larger spiders will even eat small frogs and hummingbirds.

Reproduction

Male orb weavers are much smaller than females and their sole purpose is to mate with females. Once they have mated, males are often the first meal for females. Females will produce one or more egg sacs that contain several hundred eggs per sac.

Behavior

Orb weavers are most notable for the large webs they create. These webs are circular in shape and highly organized with several radial strands of silk that look like wagon wheel spokes that are connected by concentric circular strands. These webs can measure up to 3 feet in diameter! Orb weaver spiders are typically nocturnal, building and repairing their webs at night.

At dawn, some orb weavers will tear down their webs and eat them to take in moisture from the dew that collects on them and to prevent larger animals like birds from becoming trapped in them.

Orb weavers aren’t hunters or wanderers and stick pretty close to home. They usually sit inside their webs and wait for prey to be trapped. Occasionally they will hide nearby and leave trap lines that vibrate when the web has been breached. Once something has been trapped in the web, the spider will bite and paralyze it and wrap it in silk to eat later.

Orb weavers are usually spotted around homes and gardens in late summer and fall.

Risk

Orb weavers aren’t considered a significant threat to humans. In fact, they are considered beneficial to have around as they consume pests like mosquitoes and beetles that can cause problems for you and your plants. These spiders are not aggressive and rarely bite unless they are threatened and cannot escape. The bite of an orb weaver is often compared to a bee sting and there are no long lasting effects from their bite. They are quite harmless unless their web is built in a location that is frequented by people.

Prevention

Although orb weavers are considered harmless (and even beneficial) some people just don’t like the idea of a creepy spider hanging around their home. Decreasing the population of other insects around your home that they can use as a food source will help deter them from hanging around and send them off somewhere else in search of food. Sealing holes, cracks, and gaps in the exterior of your home helps eliminate entry points for them indoors. Removing ground litter and other items they can use for shelter or harboring will also keep them from taking up residence in your yard.

If you have a problem with spiders or any other pests in or around your home, you can always contact a professional pest control company who can provide you with a free inspection to help you identify what type of pest you are dealing with and set you up with the appropriate treatment and prevention plan for your situation.

Orb weaver spiders are members of the spider family Araneidae.

Spiny orb weavers can catch nocturnal insects in their wheel-shaped webs. The black widow spider is a species known to be highly poisonous.

Female orb weavers lay eggs in clutches. The female spins an egg sac which is attached to the underside of a leaf to hold 100-300 eggs. The female spider will kill to eat the male spider after laying eggs. Baby spiders stay in the egg sac throughout winters and then they hatch within a couple of weeks. After these tiny spiders emerge from their egg sac, they start making their small webs. The group of such web builders can be easily found in a garden, field, or forest. This orb weaver then disperses in the wind by attaching itself to a small length of silk. An adult orb weaver's lifespan is about 12 months. The length of an average orb weaver spider is 4.8 to 5.1 cm.

Spiny orb weaver spiders have a broad abdomen that has white and yellow markings. Particularly, they are not considered dangerous despite their formidable appearance. They have hairy and spiny legs. Males and females die after eggs are laid. A baby orb weaver has to grow up without a family.

The golden silk orb weaver has many different organisms as its prey. The range of the prey goes from small flies to small insects. They are found particularly in mangrove habitats.

Can you handle an orb weaver spider?

Yes, you can handle an orb weaver spider. Orb weavers are known to display very docile behavior. They are non-aggressive spiders. Orb weavers are not considered dangerous to people. Although weaver spiders are poisonous, they do not have enough potential to harm humans or their pets. Instead, orb weavers are considered useful as they will catch and eat a lot of insects.

Weaver spiders are beneficial to us, even though they look imitating. They help us by eating insects which are considered pests. Some weavers eat and rebuild their web at night. To avoid an invasion of orb weavers, close off any openings which can be accessed by them.

Like other spiders, orb weavers will also tend to attack or show aggressive behavior if they feel a threat nearby them. A common way in which spiders show aggression is by bouncing on their webs. Destroying, disturbing, or breaking their web which is their home can result in an attack by them, in the form of a painful bite. The bite by an orb weaver spider can cause itchy welts on your skin. They are not long-lasting and these bites are often compared to a bee sting. Although orb weavers lack potent venom, if you are bitten by some other species like black widow spiders, it can be considered dangerous and a risk to your health.

How dangerous are orb weaver spiders?

Orb weaver spiders aren't regarded as a major danger. They are completely harmless unless they construct their web in an area that is often visited by humans.

All species of spiders have poison in common with other arachnids. Venom from just a small percentage of snakes is lethal to humans. Contrary to popular belief, they don't typically attack their victims when they're asleep. According to researchers at the University of Minnesota, more than 80% of reported spider bites are caused by other arachnids or insects. Typically, a spider bite leaves two puncture scars on the skin, although this isn't always the case. They aren't considered a danger. Spitting orb weavers' bites may cause mild swelling, reddening, and discomfort because of their poison. However, there are notable exceptions and you may need medical treatment, even though death is unlikely for most healthy people.

What happens if an orb weaver spider bites you?

Orb weavers tend to bite only when they are threatened for their survival or are unable to escape from the trap. If you get bitten by an orb weaver the bite and injected venom can be treated. Unless the victim is hyper allergic to the venom there are no long-term implications for a bite from an orb weaver. The bite from the brown recluse spider is painless and often goes unnoticed. You will feel some minor burning at the time of the bite. It takes two to three hours for the symptoms of the bite to develop.

Recluse spider bites can make you sick if not treated in time. Wash the bitten area with soap and water. Apply ice to that area and try to keep it still. Wounds might appear purple or black. A bite from a recluse spider might take up to eight hours to make the flesh rot. However, recent studies show that necrosis is instead caused by an MRSA infection and not by the bite itself.

Are orb weaver spiders poisonous to dogs?

Spiders are not the kind of pets you could cuddle or which can act as companions to most humans. Spiders are hobby animals and therefore their behavior is fun to observe. Spiders are less messy and their requirements are less. Pet shops stock non- or low-venom spiders which are easily handled with little care and eat anything ranging from pests to other insects. These spiders don't pose much of a threat to dogs. They are generally docile in nature and don't have very potent venom. Their poison shouldn't be dangerous to an animal bigger than a small bird. So, even though orb weaver spiders are poisonous, their bite is neither lethal nor poses a risk to dogs.

Spiny Orb Weaver Spider Diet

The food of spiny orb weavers, like that of most other arachnids, consists mostly of tiny insects that they are able to trap in their webs. Spiny orb weavers are known to prey on a variety of insects, including moths, beetles, mosquitoes, and flies. By biting their target, they are able to immobilize them and then eat the insides of their victim.

To bite their prey, fangs are used by all orb weavers. Toxins are produced from the glands of venom. These toxins are used to digest the prey by paralyzing them. It is also observed that bigger orb weavers, also known as the Argiope genus, eat small frogs and hummingbirds only if they are ensnared within their webs.

How to get rid of spiny orb weaver spiders?

An orb weaver spider’s diet particularly consists of insects. For them, insects are considered their primary food source. One way to get rid of spiny spiders is to get rid of these small insects first. By contacting your local pest services, you can get rid of these spiders that have infested your house.
