Downside: Peels dry out and lose potency quickly. Replace weekly.
Diatomaceous Earth (DE)
Why it works: This fine powder
is made from fossilized algae. It damages the exoskeletons of insects and arachnids, causing them to dehydrate and die.
How to use: Lightly dust DE in corners, along baseboards, behind appliances. Use a bulb duster for precision.
Important: Use food-grade DE (not pool-grade). Wear a mask when applying (the dust is irritating to lungs). Keep away from pets and children.
What About Chemical Spiders Repellents?
If natural methods don’t work, you can use commercial products. But use them carefully.
Pros: Very effective, long-lasting.
Cons: Toxic to pets and children, harmful
to beneficial insects, may have health risks with prolonged exposure.
If you use chemical repellents:
Follow label instructions exactly.
Keep pets and children away during application.
Ventilate the area.
Store safely.
For most homes, a combination of physical prevention (sealing cracks, cleaning webs) and natural repellents is sufficient.
