Keeping Spider Garden Pests at Bay

Table of Contents

Spiders play a crucial role in maintaining the ecological balance of gardens by preying on other harmful pests that can damage plants. However, when their population surges, and they pose a threat to humans or other organisms, it becomes necessary to control their numbers. Listed below are some natural ways to keep spider garden pests under control.

Spider Repellent Plants

If you want to steer clear of pesticides and insecticides, spider repellent plants are an excellent option. Here are a few plants that repel spiders:

Marigold

Marigold plants come with a natural chemical called pyrethrum, which works as an insecticide against many garden pests, including spiders. You can plant marigolds around your fruits and vegetables, and they will keep the spiders away while keeping the plant pests in check as well.

Lavender

The smell of lavender is known to drive spiders away because the scent is unpleasant to them. Plant lavender bushes near doorways, windowsills, or commonly used outdoor sitting areas to prevent spiders from entering homes.

Peppermint

Peppermint oil serves as a natural insecticide due to its strong odor, which makes it useful against harmful pests, including spiders. You can use peppermint essential oil in a spray bottle and spray it around your home and garden to keep spiders at bay.

Natural Spider Pest Control

Suppose spider repellent plants do not work for you. In that case, there are plenty of natural pest control solutions to tackle spider infestations in the garden.

Vacuuming

One of the most effective and immediate ways to manage spider populations indoors is by vacuuming them. Use a high-efficiency filter vacuum cleaner to remove spiders from their webs and around windowsills, doorways, or other areas where they might enter the house.

Citrus-based Sprays

The strong acidic smell of citric acid found in lemons, oranges, and limes repels many pests, including spiders. You can spray citrus solution around the house and garden to keep the spiders away. Mix one-half cup lemon juice, two peeled garlic cloves, and one teaspoon dish soap with one quart water for an effective all-purpose pest control solution.

Diatomaceous Earth

Diatomaceous earth is the dried sedimentary remains of algae with sharp edges that cut through the pests' exoskeletons, dehydrating and killing them. This substance works as an insecticide against many pests, including spider garden pests, by effectively penetrating the spider's waxy layer to cause dehydration.

Beneficial Insects to Combat Garden Pests

Using beneficial insects to combat harmful pests are no less than a miraculous solution. These predators kill harmful insects without any harm to your plants.

Praying Mantises

Praying mantises are helpful predators that feed on other insects like spiders, stink bugs, and caterpillars. They are facultative generalists and will eat whatever they can catch.

Ladybugs

Another popular beneficial insect is ladybugs. They feed upon aphids, scale insects, spider mites, and other similar pests that infest gardens.

Sphecid Wasps

Sphecid wasps are great hunters that attack prey including spiders when they are busy making their webs.

Organic Pesticides for Controlling Spiders

Some organic pesticides can be safely used to control spider populations without harming the beneficial organisms or plants.

Neem Oil

Neem oil is not only effective against spider garden pests, but it also acts as a natural fungicide, insecticide, and repellent. Its active ingredient disrupts pests' hormones, reducing their egg production and breeding.

Pyrethrum Extract

Pyrethrum is an extract derived from dried chrysanthemum flowers. It is a natural insecticide that attacks the nervous system of pests, including spiders. It is safe to use in the garden because it degrades within hours, leaving no residues.

Rosemary Oil

Rosemary oil is another potent natural insecticide that works on spiders efficiently. It contains camphor, carvacrol, and eucalyptol that have potential anti-insect properties.

It is always good to remember that spiders play a vital role in the environment and pose no harm if they remain within a controlled number. Some garden spiders are even beneficial, preying on other harmful pests that damage your plants. If spider presence becomes concerning, the above-mentioned methods could serve well for natural, organic control solutions instead of synthetic pest control solutions.
