Apart from that, these garden spiders are commonly present all over the United States, Canada, and Mexico.

They thrive in sunny areas and weave their webs around plants. Mostly, they live in backyard gardens or lawns.

Additionally, these spiders are relatively giant and weave circular webs, commonly known as orb-webs. These spiders belong to the orb-weaving arachnids.

Most of the other spiders have two claws on each of their feet. But the orb-weaver family has an additional claw that helps them weave the complex design of their webs.

The most distinguishing characteristic of garden spiders is that it has black and yellow markings that look like spots or bands spread across their abdomen.

These colors are standard on the female garden spider, with a white or gray front part of its body known as the cephalothorax.

Aside from that, female garden spiders are bigger than their male counterparts. Male garden spiders have a dull brown color with a thinner and smaller abdomen.

In addition, the female spiders are about 0.75 to 1.1 inches long, while the male spiders are 0.20 to 0.35 inches long. Garden spiders have eight legs, four pairs on each side, and many tiny eyes.

As the female spiders are enormous and have more bright colors, they are easily and commonly noticed in nature as compared to male spiders.

Garden spiders are pretty large and form giant webs. This is one of the primary reasons why they look so threatening and scary.

No matter how huge and scary they look, they are entirely harmless. In addition, garden spiders don't bite unless you capture or provoke them.

Additionally, garden spiders are most dangerous to the insects in your garden. These spiders make large circular webs to trap all kinds of insects in them.

Insects like grasshoppers, moths, bees, wasps, or any other flying insect that may get caught in the orb web, become the source of food for these spiders.

Aside from that, garden spiders don't usually bite humans. They don't show aggressive behavior towards humans unless they feel threatened.

Besides, garden spiders are healthy for your garden as they help maintain the insect population. So, let your friendly neighborhood spider do its job by leaving it alone.

In fact, it is said to have hurt less than a bee/wasp sting. So, if you ever get bit by a garden spider, here is how you should treat it.

  • You should always wash the bitten area and sanitize it thoroughly to prevent any infection. Because even if the spider bite isn't poisonous, an infection could do a lot worse.
  • Most of the time, the spider bite will end up swelling. The best way to treat the swelling is by applying an ice pack to it at intervals of ten minutes.
  • Apart from that, you can also reduce the swelling by elevating the site of the spider bite.
  • The bite can end up feeling very itching. If any home remedies aren't working, Benadryl (Diphenhydramine) is the best solution.
  • If the bite stays for more than a few days and blisters start to form, you should consider an antibiotic cream.

While garden spiders are harmless to humans, there is no guarantee that every spider you find in your garden is of the exact nature.

Some of the dangerous spider species include tarantula, black widow, Brazilian wandering spider, and brown recluse.

This is why it is important to seek medical attention if you are bit by any one of these spiders. This will help you avoid some serious complications.

Garden spiders have a life span of about one year. The female spiders usually die after the mating season when the temperature gets too cold.

Female garden spiders typically live for years if the weather and temperature conditions are favorable. On the other hand, male spiders typically die not too long after the mating season.

Garden spiders mate once a year. The female spider lays thousands of eggs after the mating season. The eggs are silk-covered and hatch around spring or autumn.

The newly hatched spiders then either make themselves at home in the place they were born, or the wind blows them away to a new territory.
