Do Spiders Come Out At Night? Nocturnal Arachnids


For many people, the mere sight of a spider is enough to send them running for the hills, and their nocturnal habits only add to their fearsome reputation.

Of course, there are also some real dangers that come with encountering a spider in the dark. For starters some species are venomous, and their bites can be deadly.

However, knowing when spiders are most active at night can definitely help you avoid crossing paths with one when you least expect it.

Why Are Some Spiders More Active At Night?

Most spiders are nocturnal arachnids, meaning they are most active at night, and there are several reasons why spiders come out at night:

  • Spider’s Prey Are Also Nocturnal: For one thing, most of the spiders’ prey are also nocturnal, so it makes sense for them to be out hunting when their food is most active.
  • They Can Avoid Predators: being active at night helps spiders avoid predators like birds and bandicoots which are most active during the day.
  • They Are Sensitive To Daylight: Some spiders that have more than two eyes like the wolf spider become more sensitive to light exposure and as a result, prefer to come out at night.
  • To Avoid The Heat: Spiders are cold-blooded creatures, which means that they rely on their environment to regulate their body temperature. During the day, when it is hot outside, spiders will seek shelter in cool places like caves or under rocks.

So as you can see, there are a few reasons why spiders come out at night! and if you’re looking to catch a spider for study or observation, nighttime is probably your best bet. Just be careful not to disturb their natural habitat too much.
