Spiders 11

Houseplants add a touch of nature to your indoor spaces, purify the air, and can even boost your mood. However, they can also attract unwanted guests – spiders. While spiders are beneficial in controlling other pests, their webs can be unsightly and some species can harm your plants. This comprehensive guide will help you understand why spiders infest houseplants, how to identify an infestation, and most importantly, how to keep spiders out of houseplants.


To keep spiders out of your houseplants, consider growing spider-repellent plants like lavender or basil nearby, regularly clean around your houseplants, and use a citrus-scented dish soap solution to wipe your plants. Increasing the humidity around your plants and washing their foliage can also deter spiders. If needed, use insecticidal soap or introduce natural predators like ladybugs to help control spider populations.

Why Spiders Love Your Houseplants

Spiders are attracted to houseplants for several reasons. First, houseplants provide hiding spots, moisture, and the possibility of insects for the spider to eat. Conditions that invite spiders into your home include dampness, darkness, and peace. Tall plants like sunflowers can also attract spiders due to their ability to spin larger webs.

A few factors that attract spiders to your home include:

  • Presence of insects: Spiders feed on insects, so having insects in your home can attract spiders.
  • Moisture: Some spider species are attracted to damp environments, such as basements, bathrooms, or areas with standing water.
  • Warm and dark spaces: Spiders prefer dark and secluded areas, which can be found in basements, crawl spaces, attics, and garages.
  • Clutter: Cluttered areas can provide hiding spots for spiders and their prey.

Identifying Spider Infestation in Houseplants

Before you can eliminate spiders from your houseplants, you need to be able to identify an infestation. Some common signs of a spider infestation include:

  • Pale markings or stippling between leaf veins.
  • Discolored, speckled, curled, dried, or shriveled leaves.
  • Leaves turning yellow and developing a dusty appearance.
  • Tiny webs forming over flower buds, between leaves, or on the lower surfaces of the leaves.
  • Silvery dots or patterns on the leaves.
  • Small, delicate webs in corners of stems or underneath leaves with tiny white, brown, or red dots scattered throughout.

How to Keep Spiders Out of Houseplants

Now that we understand why spiders infest houseplants and how to identify an infestation, let’s discuss some effective strategies for keeping spiders out of houseplants.

Grow Spider-Repellent Plants

Some plants have strong scents that spiders dislike. Consider growing basil, lavender, mint, rosemary, or lemongrass near your houseplants to deter spiders. You can also use essential oils derived from these plants as a natural spider repellent.

Use a Dish Soap Solution

Mix water and citrus-scented liquid dish soap to create a spider-repellent solution. Wipe your houseplants with this mixture using a cloth or paper towel to remove any spiders or mites.

Increase Humidity

Spider mites prefer warm, dry environments. Increase the humidity around your houseplants by using a plant humidifier or regularly misting the plants with water.

Wash Plant Foliage

Use a soft cloth or a forceful spray of lukewarm water to wash the leaves of your houseplants, which can help reduce the spider mite population.

Regular Cleaning

Clean your home regularly, especially around your houseplants, to prevent spiders from finding a suitable environment to live in.

Use Insecticidal Soap

Both indoor and outdoor plants can be washed down with insecticidal soap to get rid of spiders and spider mites.

Introduce Natural Predators

If you prefer a natural approach, consider introducing beneficial insects like ladybugs or lacewings to your indoor garden, as they can help control spider mite populations.


Maintaining spider-free houseplants is a continuous process that requires regular inspection and care of your plants. By implementing the strategies discussed in this guide, you can effectively keep spiders out of your houseplants and enjoy the benefits of indoor gardening without any unwanted guests.
