Hairspray immobilizes and kills spiders by gumming up their fine hairs (setae) and sealing their respiratory openings (spiracles), suffocating them and preventing movement; it acts as a quick, non-toxic alternative to bug spray, though it can be flammable and messy, essentially freezing the spider in place as it dries and dies.
If you don't have a can of Raid, then you can improvise with some hairspray. The spider won't die immediately, but once that hairspray dries, it's time to say goodbye to that multi-eyed intruder.
I was surprised that just a few sprays killed the spider in like 30 seconds. Since then I've used it on other spiders too with the same effectiveness.
Salt is a natural type of spider poison, so it makes an effective pest control aide. Dissolve an ounce of salt (1/8 cup) in a gallon of warm water, and pour the saline mixture into a spray bottle. Spray the salty solution directly onto a spider to kill it. Saltwater is also effective at killing spider nests.
Most households already have it, and the spray is sticky. It makes the wings of flying insects unusable and seals the breathing orifices to suffocate the insects. “It is water-soluble, so it can be easily wiped up with a damp cloth and leaves no stain on curtains or wallpaper.
The entomology literature has historically suggested insects cannot feel pain, leading to their exclusion from ethical debates and animal welfare legislation. However, there may be more neural and cognitive/behavioural evidence for pain in insects than previously considered.
Bugs hate strong, pungent, or overpowering natural scents, with peppermint, citronella, lavender, eucalyptus, and tea tree oil being top contenders, alongside vinegar and certain herbs like basil and rosemary, which disrupt their navigation and sensory systems. While no single scent universally repels all bugs, these strong aromas create an unpleasant environment, making them effective natural deterrents for common pests like mosquitoes, ants, and flies.
There is evidence consistent with the idea of pain in crustaceans, insects and, to a lesser extent, spiders. There is little evidence of pain in millipedes, centipedes, scorpions, and horseshoe crabs but there have been few investigations of these groups.
Spiders avoid people, animals, and most insects – except for the one's they're about to eat of course. As stated above, most spiders are relatively small. That makes them especially vulnerable. Many birds and animals may try to eat spiders, or at the very least, they'll probably interfere with the spider's food source.
Spiders hate strong, pungent smells, especially essential oils like peppermint, tea tree, and lavender, as well as scents from citrus (lemon, orange), cinnamon, eucalyptus, and cedar, which disrupt their senses. You can deter them with DIY sprays using these oils mixed with water, or use plants like basil and marigolds, or even vinegar, though vinegar's effect is temporary.
Quick Ways to Kill a Spider
Squish the spider with a long-handled broom or other solid item. Spray the spider with an over-the-counter insecticide. Soak the spider with a natural pesticide like white vinegar. Set off a pest control bomb while you're away from your home.
TERRO® Spider Killer Spray
This water-based spray kills an array of spiders including black widow, brown recluse, and hobo spiders.
Spiders are repelled by the smell of peppermint, tea tree, and eucalyptus oils. Mix a few drops of your oil of choice with water in a spray bottle and spritz doorframes, windowsills, and other entry points. Place conkers (horse chestnuts) or citrus peels in corners and windowsills.
You should never squish a spider because it can release dozens of baby spiders if it's a mother carrying eggs, attract pests with released pheromones, cause allergic reactions from its internal fluids, leave stains and odors, and you'd be killing a beneficial predator that controls other insect populations. Most spiders are harmless to humans, and squishing them can backfire, worsening pest problems or causing messes.
10 Tips on How To Get Rid Of Spiders Easily
Windex is a popular household cleaner that is considered very safe for humans, and very dangerous for pests. If you see a pest inside of your home, spraying them with Windex often means instant death. Windex can be very effective for spiders, and for killing large numbers of ants.
However, wasps, lizards, and birds are the main spider predators.
While the theory is unproven, it is likely that spiders can detect human fear.
Spiders, despite lacking vocal cords, have evolved several methods for producing spider sounds. Their primary mode of communication uses vibrations - a sophisticated system that involves sending and sensing signals through their webs or the ground.
spiders, and octopuses have blue blood. Certain bottom-dwelling marine worms have green blood. Sea squirts have purple blood. And a few rare animals have blood that is completely color- less.
But most spiders aren't aggressive to people, and their fangs are too small to puncture human skin. Spiders usually only bite humans when they feel threatened, like when you trap them or unintentionally make contact with them. For the most part, spiders perform a vital function by eating insects that can destroy crops.

Some fragrance notes naturally deter insects thanks to their powerful botanical compounds. “A number of essential oils—like citronella, lavender, peppermint, geranium, cedarwood, and patchouli—contain active ingredients that most flying insects find repellent,” explains Lisa Jean.
Spiders do not like peppermint, and because they “taste” with their legs, it is an easy way to keep them away. Make a mixture of 1-1/2 cups water, 1/2 cup of white vinegar, and 20 drops of peppermint oil. Spray this concoction on windowsills, entryways, and where you find spiders.
