Banana Spider

Summary: The banana spider name is used for two entirely different species of spiders; the North American banana spider and the banana spider that is found in Central and South America . The southern rendition can be deadly, but is generally found, thankfully, only in rainforests. Still, there are over a thousand reports of bites every year in areas in southern Brazil.

A reader asks: I was wondering how I can get rid of the Banana spiders outside of my house. These giant spiders make it uncomfortable for us when we are around our pool.

Dear Reader: The Banana spider, also known as the Golden Silk spider, sets up its home in areas where there are lots of insects. So, in one way that spider is doing you a favor by being there because it's eating small insects that might otherwise enter your home. Free exterminating services offered by Mother Nature. However, that particular spider is pretty big and even though they are not interested in you, it's probably not a spider you want to suddenly find crawling in your hair.

Consistently knocking down the webs of any spider will cause the spider to relocate. The web is the spider's means of surviving. 


The other thing to consider is what is attracting the spider's food to the area around your house. Dense vegetation and lights will attract lots of insects upon which spiders thrive. Outdoor lighting should be turned off when possible. Also, consider changing the outdoor bulbs to sodium vapor bulbs. They are more expensive, but they last longer and attract fewer flying insects. You might also consider closing the shades of any windows facing the pool enclosure. Lights from indoors will also attract flying insects at night.

These spiders rarely bite people. For most, a spider bite may cause a small bump, but some people might have an allergic reaction causing more adverse effects. For the most part a spider's bite is not fun, but it won't kill you.

I live on 40+ acres in Live Oak, Florida. I have a major problem with banana spiders. Even though I knock down the web, they still return. My husband has to drive the tractor around the property to clear a path for me to walk. They are everywhere. I've walked into one, unaware it was there, and it scared me half to death when I realized it was crawling on me. I'd like to get rid of them. I can't afford an exterminator. How can I limit the spiders?

A pesticide fogging machine will help disperse spiders, but it would require the help of a professional with specialized piece of equipment.

We have a huge banana spider and her mate living right outside our window at work. We tried "relocating" her and her mate to a nearby tree but were amazed to find that within a 1/2 hour, she was back in her web by the window. Such determination has to be admired! We found her mate on the tree and moved him back to the web by the window so they could be together again. They are good pest control but above and beyond that it was a Herculean effort for her to make her way back to the window and we figure she deserves to be there!

The spiders live in the wooded areas surrounding the homes we build in their territory. You can kill the spiders as you find them or have your children play in areas not occupied by the spiders.

Is it true that being bit by one of these banana spiders can cause a male to have a long lasting erection?
if so, is there an effect on females?

The venom of the spider can cause priapism, a potentially harmful and painful medical condition in humans in which the erect penis or clitoris does not return to its flaccid state. Erections resulting from the bite are uncomfortable, can last for many hours and can lead to impotence.

Have banana spiders in my dog pin and I can't check her and her pups what should I do ?
Ummm.. Check the dogs

First and foremost take care of the dogs. You are bigger than the spider. Chances are when you walk towards it, it will Bach away. I have been within 6 inches of the 7 I have in my yard. While they are scary to look out. The are scared too. If you want to kill em I suggest a can of hairspray and a lighter or a blowtorch. Who cares... Just don't let your dogs sit out in a pin because your scared of a spider.. It's tiny compared to the average human.

Treat the surfaces of the house where you are finding spiders. Any house and garden pesticide will work.
