Are Spiders More Active At Night?

spidersatnightThere are more than 48,000 spider species and 120 families, found across the globe. Spiders are air-breathing arthropods, have eight legs, and chelicera with fangs in front, which can inject venom. Spiders are both diurnal and nocturnal, depending upon the species. Let’s discuss the nocturnal spiders.

Orb-weaver spider is one species that is very active at night. We shall understand a little more about them. They belong to the Araneidae spider family and get well known to build spiral, wheel-shaped webs, found in gardens, parks, fields, and forests.

So, are spiders more active at night? The answer is yes, but it depends upon the species. Not all spiders are active at night. There are some spider species that are nocturnal, and some are diurnal. Few spiders prey and do all of their activities at night, and few of them do it in the morning.

Nocturnal Or Diurnal

There are raging discussion forums on whether spiders are nocturnal or diurnal. The answer is that this depends mainly on spider species. Some are strictly nocturnal, while some are diurnal. Some nocturnal species have got observed to have become diurnal too.

Eyesight:Spiders with better vision, prey during the day and rest at night and vice-versa. There are spiders which have eight eyes, six, four and so on. They always have even a pair of eyes. Those with a lesser number of eyes prey using their sense of vibration. This gets felt by their body parts and also the silk attached to the web or on their legs.

Predators:Spiders have opted for nocturnal habitat, to avoid their predators, who are active during the day. However, their prey also is in large numbers during day-light. Hence, they decide on the trade-off and acclimatize accordingly.

UV rays:The UV rays from the sun affect the quality of silk that gets produced. Spiders who require the UV rays for their silk to be strong for their predatory and defense requirements are more active during the day. Those spiders whose silk-producing gel does not have much impact concerning UV rays have developed into diurnal species.

Will Spiders Crawl On You At Night?

spiderinbedIn general, spiders avoid humans, but If you have too many spiders in your house, then there are some possibilities that they can crawl on you at night.

They don’t do it for revenge or to bite a human. It can happen only by accident, and spiders may not be aware that they are climbing on you, although the chances of a spider biting you at night are very less.

If you are sleeping motionlessly, then the spider will go away, but if you are moving or rolling, then it may be bad for the spider as it can die because of it.

Usually, a spider doesn’t like to come down from the walls. Walls are a safe place for them. They only do it if they feel like they need to make their nest far away from the other spiders, which can be their competitors.

Not all spider bites human even when provoked. Spiders try to avoid humans by all costs, but some spiders can be dangerous, for example, tarantula, black widow.

If these poisonous spiders are inside your house, then it’s a matter of concern because it doesn’t matter whether you are awake or sleeping, they are dangerous and potentially life-threatening.

But the chances of seeing these spiders inside your house are very less. Unless you have these spiders in your region, there is no way you are going to see them inside your home.

Even if they are inside your house, they won’t crawl on you when you are sleeping because, as I mentioned before, spiders avoid humans.

There is a spider named Orb-weaver spider, or the garden spiders they are active from late evening onwards. They rest during the day.

First, they eat their entire web or its remnants, which got created the previous day. Rest for an hour or so.

They then construct a new web in a similar site for new prey to get trapped.

They don’t do any harm to humans.

So, in one word, you don’t need to worry about spiders crawling on you at night.

Some Ways To Get Rid Of Spiders

Here are some ways to get rid spiders:

1: Use A Glue Trap: Glue traps work well to get rid of them. Once a spider steps on a glue trap, it won’t be able to come out, and they will die. It can trap multiple spiders at the same time. Once they are trapped or dead, you can throw away the trap.

Just place the trap where you see the maximum number of spiders, and you’ll be ready to go.

2. Use Peppermint Oil: Peppermint oil also works well against spiders. The strong smell from peppermint oil repels them and will reduce the infestation.

3. Use Vinegar: The acetic acid inside the vinegar will instantly kill them. Mix equal parts of water and vinegar and spray it directly over them to get rid of them. Vinegar scent will disappear as soon as the vinegar evaporates.

4. Use Diatomaceous Earth: Diatomaceous earth is very effective against them. When spiders come in contact with diatomaceous earth, it punctures their body, and their bodily fluid starts leaking. This doesn’t happen overnight, but it happens eventually. Spread a fine layer of diatomaceous earth and put it everywhere you see spiders.

5. Vacuum The Spiders: Buy a vacuum cleaner and vacuum them to get rid of them. Once, the spiders are inside the vacuum cleaner. They will die. You can vacuum a vast number of them at a single time.

Is It A Good Sign If Spiders Crawl On You?

There is a belief that if a spider crawls on you, then you are going to have a good day. However, this is just a myth, and there is no such scientific evidence that they bring good luck.

If a spider crawls on you, it means there are too many spiders in your house, and you need to take care of that. Just by thinking about good luck, you cannot let the infestation increase as it will lead to more problems.

Normal house spiders don’t do any harm to human, and many people freak out just by looking at them and by any chance if these spiders get onto someone scared of them then, he or she can have a panic attack, which can be dangerous.

So, without getting mixed up in the superstition, it’s better to get rid of them.
