How do you get rid of spiders instantly?
If you aren’t friendly to those 8 legs, there are a few tips to get rid of them instantly.
When you first see spiders, try to catch them by using a jar or a glass. This is, of course, a friendly method since it spares the spider’s life. Make sure that the jar or glass is transparent, not too heavy or lightweight. It shouldn’t be too big.
Once you catch the spider in the jar, quickly slide the paper under it and lift the jar up. Bring the spider outside and maintain a good distance from your living area.
Other methods to chase spiders away without killing it including:
Relocate your trash bin: Spiders love flies and flies live in your trash bin.
Place horse chestnuts in your house where you see spiders.
Reduce the use of outdoor lights: light attracts insects, which attracts spiders to hunt.
Have eucalyptus as a house plant
Use cinnamon sticks or essential oils
Does spraying for spiders work?
It depends on how you use spray. If you spray directly on spiders, they can’t escape the chemicals. However, if you only spray on the ground, it is generally not so effective. Since spiders have long legs, they can keep their bellies off the ground.
Spraying on the ground can only keep spiders away for a short while.
What smells do spiders hate?
Spiders hate the smell of citrus fruits. Things like eucalyptus, lemon, tea tree, peppermint or cinnamon oils can chase spiders miles away. Spiders also don’t like the smell of vinegar.
