What Makes a Good Spider Repellent?

Many homeowners wonder "What is a good spider repellent?"

Living in a home full of creepy crawly spiders can be unsettling. You never know when you're going to encounter one! Though most species of spiders are harmless to humans (and help keep insect populations down), spiders still tend to be off-putting enough that we often wish they'd live elsewhere. There are some venomous species that can be dangerous to humans, and which you should watch out for.

Usually, when we see a spider or other bug, your first impulse might be to "reach for the bug spray," and there are several, both conventional and botanical, that are effective at killing and repelling spiders (and other pests). Many of these sprays kill on contact, and the most effective botanical sprays leave residual repellency protection that can last for several weeks.

What should you look for in a spider repellent product?

The better spider repellents will be doing its job even when you're not around and can remain effective for several months. Dusts that use botanical oils as active ingredients consistently tend to be some of the better spider repellents.

The most effective plant oil-based spider and insect dusts can be dusted and puffed into cracks, crevices, and voids inside and outside your home, and to areas where spiders can gain entry into your home and hide. Because of the specific essential oils these dusts are formulated with, they are very lethal and repellent to spiders. Spiders HATE these oils, as do most insects. By dusting a spider and insect dust like this into cracks, voids, corners, etc., areas where spiders set up their cobwebs and roam freely, mostly unnoticed by humans, it helps keep them (and other pests that they hunt) at bay in your house.

There are plenty of things you can do to help prevent spiders and other bugs from getting inside your home. Here are some more control tips.

10 Steps to Repel Spiders Naturally:

Yardwork! Keep your lawn, trees, and vegetation trimmed. 

Bug problems usually start outside. Keep bushes and shrubs in your yard cut back away from your home's exterior to deny easy access to spiders and other unwanted bug visitors. Do NOT stack firewood or refuse along the side of your home. Keep it at least 20 feet away.


Regularly clean and sweep your house and kitchen. 

Always wipe up spills, and repair pipes and faucets to eliminate water/moisture sources. You’re not just trying to make conditions unlivable for spiders, you’re first trying to make other bugs (which spiders feed on) want to go elsewhere. To keep webs under control, remember to sweep ALL corners of your home, including the ceilings. It is important to knock down every cobweb you can find and reach.  Your goal is to make it difficult for spiders to set up shop in and around your house.



Along with keeping your home clean, you want to remove clutter, like empty cardboard boxes, items that are stored under beds, under sinks, and in closets, piles of magazines/newspapers, etc. You’ll not only get rid of hideouts for spiders, but also for cockroaches, scorpions, mice, and other pesky bugs.


Thorough Vacuuming. 

Regular superficial vacuuming alone won’t disrupt spiders and their ways of life. They hide and they build webs.
  • Vacuum behind and under furniture, and in corners.
  • Use a vacuum extension to clean ceilings, ceiling corners, and light fixtures.
  • Once per season, or at least twice per year, clean your air ducts.

Close your chimney flue. 

Keep your flue closed when you’re not using your fireplace. This will help keep spiders out and will also help lower your utility costs. 


Minimize entry points. 

Patch up any holes in your foundation, caulk gaps in walls and around doors, windows, the foundation, and at utility entry points. Keep screens and weatherproofing in good repair each year. 


Use fabric grocery bags. 

Spiders and other bugs often sneak into your home via paper grocery bags. Use fabric grocery bags and wash them regularly.

Reusable grocery bags

Wash your bananas (and other fruit). 

Fruits, particularly bananas, are favorite ways for some spider species to slip into your home unnoticed. 

    Washing produce

    Spider "sticky" traps. 

    Place spider traps in areas where you often see spiders, such as behind the water heater, thermostat, under utility sinks, and even along baseboards at home

    Plant spider-repelling plants.

    Using plants to keep spiders away is an effective practice. Certain plants with a strong aroma and strong essential oils have been proven to repel spiders and other pests, both indoors and outdoors.  

    These spider-repellent plants include:

    • Basil
    • Lavender
    • Rosemary
    • Lemongrass
    • Mint
    • Lemon Balm
    • Eucalyptus


      These suggestions, plus applying an effective botanical spider and insect dust, will go a long way to not only keep your house spider-free, but it will also greatly reduce the bugs in your home that spiders hunt. And when they run out of things to hunt, they'll go to someone else's home. Remember, it's easy to spot treat and kill the spiders you see, but that doesn't solve the source of the problem, all those hidden away areas where they move around when you're not watching.
