These spiders usually spin their webs in sunny places outside where there are flying insects. These orb-weaver spider hardly get indoors unless they are accidentally carried there.

Yellow garden spiders usually relax in their webs head-down waiting for an insect to be trapped in its silk web. It will them bite its prey to inject some venom that will paralyze it before enjoying the feast.

The sac will be secured in their web and somehow hidden from the view under leaves. Once hatched from the eggs, the spiderlings will remain in the porch through winter until warm spring.

How to Get Rid of Spiders Outside

Spiders can easily get inside you house during winter to seek for warmth. Usually, they find their way in through cracks or small openings around windows and doors. Controlling the population of spiders outside can help in preventing them from infesting your home.

Before you call a pest control agency, I have a number of ways that can help in cutting down the population of spiders in your yard.

1. Clean up your yard

Spiders and other bugs prefer unkempt areas in the yard. You will find them in tall grasses, on overgrown tree branches or shrubs. Unkempt areas will also attract a great number of flying insects like mosquitoes, gnats and grasshoppers which are not only a nuisance but also attractive to arachnids.

Cleaning up your yard should involve trimming your overgrown landscape vegetation, removal of standing water in the yard and disposal of debris such as open cans, old tires, twigs and leaves. This will also go along way keeping away deadly mosquitoes out of your yard.

2. Use natural repellent spray

Essential oils are good at repelling arachnids. You can make your spray out of the oils to use outdoors for repelling garden spiders. One advantage of this methods is its friendliness to the environment. Citronella, peppermint or tea tree oil have strong scents hated by arachnids.

Mix few drops of your essential oil with water in a spray bottle and spray around the targeted area. Do it periodically and all the spiders, grasshoppers, flies and even mosquitoes will disappear from your yard.

3. Keep away pet food leftovers

Although spiders will not be much interested in food leftovers, they will come around your home as a result of other insects which serve as delicacy to them. Uncovered trash cans and pet food remains will attract a good population of roaches, flies and antis among other.

4. Contact pest control professionals

Pest control professionals will safely remove spider webs, capture the spiders and remove anything else that attract arachnids in your yard. Large infestation may necessitate a chemical control but is always not a good idea since it also affect non-target insects that are beneficial in nature.

Final Though

Black and yellow garden spiders are usually not dangerous to humans and pets. Their venom bite helps them paralyze their prey. In rare occasions, garden spiders will bite humans for self-defense or protection of their young ones.
