However, spiders can be harder to eradicate if the infestation is on your patio or deck. As it can be tough to tell whether or not the infestation is widespread.

Spiders majorly like to stay outdoors. They may seek refuge indoors during winter or summer to escape weather extremes. They get inside your home through crevices in your windows and doors.

In this brief guide, we discuss several ways you can use to get rid of spiders outside your home.

There are several things you can do to get rid of spiders:

  • Avoid keeping outside lights on as they attract insects that spiders eat.
  • Seal all the cracks and crevices in your doors and windows with caulk.
  • Mix table salt and water and spray it around the perimeter of your home and house. The solution acts as a DIY spider repellant.
  • Keep your gutters clean. Blockages in the gutter allow insects to get into the house through the crevices in the attic.
  • Seal the crevices in your porch and deck.
  • Spray a mixture of tea tree oil, citronella, lavender, peppermint, cinnamon, citrus, and water around the deck or porch.


You can also use commercial sprays and insecticides to get rid of spiders. However, when choosing spider-killing products, ensure to go for one safe for kids and pets.

Here are a few options you can consider:

Repellents. There are repellents for spiders available for use both outdoors and indoors. You can spray these compounds on plants. The good thing is that the repellents will not harm the plants since they are all natural but kill spiders.

Aerosol sprays. These sprays are effective in controlling spider infestation in garages and basements where spiders like to hang out.

Web eliminators. The product is meant to stop spiders from creating webs on surfaces such as wood, metal, and brick.

Contact sprays. Although not applicable in many cases as spiders weave webs in hidden and secluded areas. Contact sprays destroy existing spider webs.


  • Foliage and petals of different plants can be used to keep spiders at bay:
  • Plant garlic, cilantro, eucalyptus, or Osage oranges in your compound
  • Scatter chestnuts near your window sills and doorways
  • Spray a solution of two or three crushed garlic cloves and water outside your house
  • Sprinkle a mixture of peppermint oil with water around window sills and doors
  • Spray a mixture of five drops of tea tree oil, warm water, two tablespoons of dish soap, and one ounce of neem oil in spider-infested areas

Spider-killing sprays are not similar to spider repellants. As the latter rarely interferes with other living bugs in the application area. While the former will kill all of them. Therefore, use this as your last option.


The good thing about electronic repellents is that they can be used both outside and inside the home. And do not exude chemicals, making them safe for kids and pets.

Insecticides are also another option to control spider infestation in your home.

These products contain substances that damage spiders’ nerve systems leading to their death. You can find them in liquid, dust, or powder form.

Liquid insecticides are best for spraying huge regions, such as around the perimeter of your home. While dust and powder insecticides can be used for spot treatment.
