HOW TO GET RID OF SPIDERS OUTSIDE YOUR HOME?

Spiders play an important role in the ecosystem by controlling insect populations, but their presence around the home can be uncomfortable for some. As autumn approaches, it’s common to see more spiders in gardens, on facades, and sometimes even near doors and windows, as they seek shelter from the elements.

1. Understanding spiders

Common spiders in Quebec

In Quebec, the most common types of spiders you might encounter in your garden or on your terrace include:

• House spider
• Wolf spider
• Cellar spider
• Dolomedes spider

Ecological role of spiders in the garden

Spiders are natural predators that help control populations of harmful insects such as flies, mosquitoes, and aphids. They contribute to maintaining an ecological balance and reducing the need for pesticides.

Why they choose to settle around houses

Spiders are attracted to places where they can easily find food and shelter. Gardens and terraces often provide these ideal conditions due to the presence of other insects and structures where they can weave their webs.

2. Prevention: keeping spiders out

Maintaining cleanliness around the house

One of the most effective ways to prevent spider infestations is to keep your garden and terrace clean and well-maintained. Regularly remove debris, dead leaves, and piles of wood that can serve as hiding spots for spiders.

Using physical barriers

Install screens on your windows and doors to prevent spiders from entering your home. Ensure that cracks and holes in the walls and foundations are properly sealed.

Eliminating food sources

Spiders primarily feed on insects. By reducing the insect population around your home, you decrease the attractiveness of your outdoor space for spiders. Use natural methods to control insect populations, such as pheromone traps or repellent plants.

3. Natural methods to repel spiders

Using essential oils

Peppermint, lavender, and eucalyptus essential oils are known to repel spiders. An influencer of tips and recipes, Kamana Bhaskaran, demonstrated the effectiveness of a homemade spray in a TikTok video, reported by « The Mirror » and relayed by the Journal de Montréal. This video has reached over 1.9 million views since its publication last year.

Here’s how to prepare and apply an essential oil solution:

1. Mix 15 to 20 drops of essential oil with 500 ml of water in a spray bottle.
2. Add a teaspoon of white vinegar to enhance the repellent effect.
3. Spray the solution around doors, windows, and other entry points.

Repellent plants

Certain plants, such as mint, lavender, and lemongrass, are naturally repellent to spiders. Plant them around your garden and terrace to create a natural barrier.

Homemade repellent recipes

• Vinegar and water spray:
  1. Mix equal parts of white vinegar and water in a spray bottle.
  2. Spray the solution around areas where you have spotted spiders.
• Water and dish soap mixture:
  1. Mix a few drops of dish soap with water in a spray bottle.
  2. Spray directly on spiders and their webs.

Reduce outdoor lighting

Lights attract insects, which in turn attract spiders. By reducing or adjusting the lighting near entrances, you make your home less appealing to spiders.

4. Manual management techniques

Removing webs

Use a broom or specific tool to remove spider webs you find in your garden or on your terrace. This discourages spiders from settling in these areas.

Homemade natural traps

Make spider traps using simple materials:

• Sticky trap: Place sticky paper or double-sided tape around areas where spiders are frequently seen.
• Jar trap: Place a glass jar with a small amount of vinegar or essential oil inside to attract and trap spiders.

Using LED lights

Insects are often attracted to traditional lights, which can in turn attract spiders. Replace your bulbs with LEDs, which emit less heat and attract fewer insects.

Regular maintenance

Regularly maintain your garden and terrace. Mow the lawn, trim shrubs, and remove debris to reduce potential hiding spots for spiders.

If you notice a large number of spiders despite your efforts, it may be time to consult a professional. Significant infestations may require more specialized interventions.

Conclusion

Spiders, although mostly harmless, can be undesirable in our outdoor spaces. By using natural and safe methods, you can reduce their presence without harming the environment. Keeping your garden and terrace clean, using natural repellents, and encouraging biodiversity are effective strategies for controlling spider populations.
