Now scientists have found that spiders can hear you from across a room. The discovery came as a surprise because, technically, spiders do not have ears. However, the latest research shows that the hairs on spiders' legs are so sensitive that they can detect human speech from several metres away.
You'd probably never notice a jumping spider across your living room, but it would surely notice you. The arachnids are known for their brilliant eyesight, and a new study shows they have even greater sensory prowess than we thought: Jumping spiders can hear sounds even though they don't have ears—or even eardrums.
SPIDERS can identify terrified arachnophobes because they can hear their SCREAMS. Scientists have discovered that even though the eight-legged creatures do not have ears they can still pick up the sounds of terror.
It is well-known that spiders respond when something vibrates their webs, such as potential prey. In these new experiments, researchers for the first time show that spiders turned, crouched or flattened out in response to sounds in the air.
Although spiders can't feel complex emotional feelings like sadness or joy, they can feel physical pain. Almost every organism on earth can feel physical pain, including tarantulas.
Spiders do have feelings, but unlike a dog or a cat, they won't bond with you. In fact, they likely won't even recognize you. They simply aren't hardwired to be companions to humans and should never be bought at pet stores, online, or anywhere else.
While the theory is unproven, it is likely that spiders can detect human fear. However, there are only few studies about this topic and it is not yet known for certain. Different animals have sensory organs that are able to identify different stimuli.
“Our studies extended the range of auditory sensitivity to more than 3 metres – over 350 body lengths – for our spiders.” The team established that the spiders freeze when exposed to low-frequency sounds of about 80 to 400 hertz that resemble a low hum, or buzz.

Ultrasonic sound is thought to be discomforting for spiders and creepy crawlies, causing them to leave the room.
By angling each of their eye-tubes just so, the spiders have binocular vision with excellent acuity and full color perception. The secondary eyes on the side of their heads give them more or less 360º vision. Jumping spiders don't spin elaborate webs and wait for prey; they actively hunt during the day.
These eight-legged creatures hate the smell of citrus fruits such as lemons and oranges. They also don't like peppermint oils, tea tree oils, eucalyptus, and vinegar. Using any of these around your home will keep spiders away.
They sense their world mostly through vibrations and scent/taste. Jumping spiders, however, have excellent vision. They can see movement and objects much more clearly than can other spiders. They will follow your movements, including your head movements while you are looking at them.
The researchers mated 68 virgin P. globosus females with two males. They found that the number of squeezes the males made were associated with the number of times the females cried out during sex. Stridulations became more frequent if males failed to loosen a squeeze in response to a previous plea.
But new evidence now provides us with a strong argument to suggest that animals such as spiders are just as self-aware as we are.
While studies have shown that spiders are very intelligent creatures, they still have very small brains with a limited amount of space to carry out tasks and think. You do not hold a special place in that brain and hence a spider will not remember you.
They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged.
Spiders love to hide in the dark, debris-filled cracks away from humans. Be sure to give the space under your bed a lot of attention while you're cleaning. Since it tends to be dark and dusty under beds, they're an ideal place for spiders to hide away. The garbage from your kitchen may also attract spiders.
The stinky smell of sweaty socks might repulse humans, but scientists now find it enthralls mosquitoes and spiders. The odor apparently helps the creatures hunt down their victims — the mosquitoes want to feed on people, while the spiders prefer to devour the mosquitoes.
In general, anything that attracts pests can also attract spiders, as this provides an easy food source. This may include trash left around the home, uncovered human or pet food, and plants around the home's exterior.
Are spiders afraid of humans? Yes. This is why spiders are most commonly encountered in seldom used areas such as garages, attics, basements, closets, or guest rooms. Spiders are antisocial and try their best to avoid human contact.
Spiders are not attracted to heat and can live quite comfortably in a wide temperature range. Most spiders prefer temperatures hovering around 70 degrees.
We found that perceived fear and disgust of spiders were triggered predominantly by enlarged chelicerae, enlarged abdomen, and the presence of body hair. Longer legs were associated with perceived fear as well; however, the presence of two eyes did not produce any statistical significance in terms of fear.
No, dead spiders won't attract other spiders. At least not directly, but it might indirectly as their carcass can turn into food for other insects and attract other spiders to eat said insects.
There are many types of spiders in our homes. Some are harmless and non-poisonous, while others can be dangerous if they bite or sting. Here are some common house spider species that are harmless: Cellar spiders.
They may give you the creeps, but spiders are really just more of a nuisance than a health hazard. In fact, having a few spiders around your home can be advantageous as they will help to keep away harmful pests and disease-carrying insects like ticks, fleas, and cockroaches.
