All About Garden Spiders

Garden Spiders, or Argiope aurantia, are often spotted in leafy gardens during the spring. They are easily noticeable because of their large size and intimidating appearance. Garden spiders typically have black and yellow limbs and long legs. 

These spiders weave orb-shaped webs, so you may spot these webs somewhere in your garden, which confirms their presence. These webs are attached to the plants, which tether them.

The webs have a distinct zigzag pattern, possibly used to alert birds not to fly through them. Some also speculate that the pattern signals that the spider is ready to mate. However, the most probable reason for this pattern is to trap insects easier.

These spiders are most active during the spring and summer so you may see these webs often during these seasons. 

Their venom is used primarily to indispose their insect prey. It cannot harm humans or pets, so you wouldn't have to worry about your pet getting poisoned if they suddenly wander into your garden.

Benefits of Having a Garden Spider

If you see a garden spider--especially for the first time--your first reaction would be panic. You could somehow be tempted to get rid of it or kill it. However, getting rid of them isn't wise since they have a lot of benefits that can make your garden thrive. 

For instance, garden spiders catch insects that are potentially harmful to your garden. They can eliminate moths, flies, beetles, and wasps, which are part of their diet. With spiders controlling them, you won't find half-eaten leaves when you tend to your garden. 

They can be a natural pesticide since they overwinter in the garden, so they resume their diet once the season is warm enough. They can catch all the harmful pests even if you hold off the insecticide during the start of the warm season. 

Are There Drawbacks to Having a Garden Spider?

There are no direct drawbacks to having this spider in your garden. However, they may turn aggressive and bite you if you accidentally touch them. This is possible if you're tending to your garden and accidentally moving your hand along them or their eggs. 

Depending on the dog or cat's general health, a garden spider's bite can also be serious. However, reports of this are rare. If you're worried, don't let your dogs or cats around the garden where they can potentially move through webs or spider eggs. 

When they bite, you will initially feel a sting similar to a bee's. Their venom could enter your body, and while it isn't poisonous, it can still cause uncomfortable swelling and redness. 

If you somehow get bitten, make sure to clean the area with soap and water. Do not scratch it, as it may get infected. You can apply a cold compress on the area to reduce the swelling.

After that, you can transfer the garden spider to your garden or take them outside with their web. 

Can You Keep A Garden Spider As A Pet?

Although they are harmless, keeping a Garden Spider as a pet is not recommended. They will hardly benefit anyone since a garden spider cannot spin properly outside its natural habitat. 

However, if you can build a large tank that accurately mimics a garden, you may place them there. You can build a tank filled with large plants where they can build their webs.
