Joro spiders! When you spot them, they will be hard to miss.

Trichonephila Clavata, the Joro, belongs to a family of spiders known as orb weavers because of the highly ordered wheel-shaped webs they weave that are 3 inches wide and 10 feet deep.

The female Joros can measure three inches wide when they extend their legs and have striking yellow, blue, and red markings all over their body.

The size difference between this spider species and other species give them a frightening feature. Finding one can be scary and unusual.

Before you freak out, you should know that while Joro spiders control bothersome insects like mosquitoes and stink bugs, they take over areas where they attach their orb-shaped webs.

As they do their business, these spiders and their impressive webs are impossible to overlook. Knowing more about these species and what you can do to repel them is beneficial.

The following are the control tips that prove effective:

1. Use Essential Oils

Essential oils are effective remedies with an aroma appealing to humans but repulsive to insects. Because these smells repel bugs, spiders will also avoid areas where you apply them.

Joro spiders build their webs where there is a reasonable quantity of airflow to catch insects on their web.

The easiest way to use essential oils is to mix them with water and spray them around your yard and in areas where Joro spiders are most likely present.

Such areas with sufficient airing include surfaces next to porches and on trees.

Peppermint, eucalyptus, horse chestnut, citrus, and tea tree oil can be used. Apply these natural spider repellents after every few days for the best results.

2. Lower the Humidity Levels

Joro spiders prefer warm, humid environments because there are more insects there, such as mosquitos and biting flies, that they feed on.

Make your yard inhabitable by removing any standing water from the area.

3. Use Insecticides

Insecticides from the store and spray treatments work well to keep spiders away. These pesticides can be helpful when dealing with a severe infestation because they act as a barrier to keep Joro spiders out.

Apply insecticides wherever you see these spiders or their webs and on your porch, including the corners.

Because insecticides contain harmful chemicals, it is crucial to read and use all label directions cautiously.

4. Turn Off Outdoor Lights

Outdoor lights attract insects, which will attract Joro spiders. So make it a habit of turning off outdoor lights. Also, a Joro spider may build a web near a porch light or nearby lights on your property to catch bugs.

So, by keeping lights off, bugs will stay away, and if they are not around, Joro spiders will find other spots that are more welcoming.

5. Tidy Up Your Yard

Joro spiders enjoy dense vegetation, wood, and leaf piles, and by routinely cutting trees and bushes, you can provide them with fewer places to nest.

Stink bugs are Joro spider’s favorite, and since they thrive on plants, it is crucial to clear the area around your house of vegetation.

If you have a major Joro spider infestation, consider moving shrubs, trees, and other plants further away from your house. Joro spiders may encamp near your home in the rich foliage.

6. Pull Down Their Webs
