How High Can A Spider Climb?

spider climbing wallsThe orb-weaver spider can reach high altitudes because of the ability of ballooning. They can climb the tallest building, climb mountains, climb tall trees. If there is food, they can keep on climbing and reach even higher altitudes. 

The chances of climbing a high rising building are the lowest because the spider will not find any food over there. 

If there was plenty of food for the spider at that height, then the spider could have climbed the tallest building.

Spiders usually avoid climbing too high as they get plenty of food when they make their nest in a jungle or between trees. Along with that, the spider needs proper airspeed to build their spider web.

If the wind speed is too high, then they won’t be able to make their web correctly. The web may break if they try to catch prey. The spider uses the wind speed to jump around to build their nest.

Too much speed will make it difficult as they will be blown away by the wind. That is why you will not see spiders in high altitude. But they can climb to a high altitude if they want to.

Climbing to high altitude is hard work, and they cannot do it unless there is motivation, which is food or unless food is scarce. 

If spider infestation is high in your house, you can get rid of insects to keep spiders away from your home.

If there is less insect or no insect in your house, then the infestation will automatically decrease. Instead, they will make the net nearby garden or jungle where they can get plenty of food. 

They can climb trees because it’s relatively easy for them. Making nest along the tree allows them to capture insects much easily. 

Some spiders can also reach high altitudes to avoid competition. They will climb lofty heights if they cannot compete against other spiders. 

Climbing high altitude is not a problem for spiders. You’ll see them on higher heights of mountains. Anywhere they can find food, they stay in that place.

 Spiders also avoid humans, and that is the reason why you’ll not see many spiders on a high rising building. If you stay at a high altitude, then there will be few or no spiders at all.

 Spiders can fly thousands of meters above sea level through ballooning. So reaching your house is not a problem for them. 

Fortunately, unless there is a reason to climb high rising buildings, which is always food, they will not do it because it is too much risk.

Can Spiders Climb Glass?

Yes, spiders can climb on the glass. They can climb anywhere. It is because of millions of tiny hairs on their legs that get attached to the surface. 

Every surface is rough at a molecular level, so this hair can capture the surface and allow the spider to climb. Glass, which looks like a plain surface, is rough at the molecular level. 

So, spiders can climb it quickly, but if any liquid is sprayed or poured on the glass then, it will become tough for the spider to climb. They fall while trying to climb because the surface becomes slippery. 

You can see the same phenomenon in a wet basin. The spider cannot climb on a slippery basin because the spider cannot grab the surface when liquid is there.

Once the spider falls on a wet basin, they cannot get out. The spider will try repeatedly but will fail. Even big spiders cannot escape from a wet basin.

 Some building has a glass exterior. That glass appears to be smooth from outside, but it is rough at the molecular level. Spiders can easily grab the glass exterior of the building, much like any other object, and can climb to the top of the high rising building.

But if the surface is wet, then they cannot climb through the glass. Instead, they will still try to climb the building through the concrete side, which in this case, is the interior of the building.

Spiders can climb through wet concrete because concrete absorbs liquid, whereas glass does not. If a building exterior is entirely covered with glass and if a spider wants to climb that building. 

Then the spider will start climbing when the surface is dry and can also use ballooning to get to the top. Rain can make it very difficult for the spider top climb to the top.

 Spiders are not interested in climbing the top of buildings because they get plenty of food on the ground.

Why Do They Climb Hills

spiderclimbinghillsSpiders climb mountains to find food like any other organism and also to avoid competition. The same species of spiders can be found on the ground and mountains because some of them migrate for food.

Once a spider reaches mountains. They reproduce and grow their population there. It isn’t very easy to determine when the first ancestor of that spider came to the hill and started growing over there, but what people see is there are spiders in the mountains and comes to the conclusion that spiders can climb mountains. 

But that generation may or may not have climbed to the mountains; instead, they stay there for generations. One of their ancestors climbed the hill in a not so distant past and started reproducing, thus growing their population.

Can They Climb Upto Space?

If there was a building high enough to reach space, then also spiders won’t be able to climb that building. There are many reasons why. There will be low oxygen, high wind speed, temperature changes, pressure changes. 

The spider will die instantly if, by any chance, the spider crosses the earth’s top layer and reaches space because space is a vacuum. No animal or insect can survive on space without proper equipment. 

Humans are the only species who can do that because we have the technology. Climbing from the surface of the earth to the space is impossible for spiders. They are excellent climbers, but it’s beyond the limits for any spider.

They can climb the tallest tree, i.e., the redwoods, which can reach up to 90 meters.

They can also climb the high rising buildings like Burj Khalifa, but the chances of seeing a spider in that height are very tiny. So, you don’t need to worry.

How Fast Can A Spider Climb?

The fastest spider can travel at a speed of 1 mile/hr on land, but while climbing, they will not reach this speed as there will be a lot of factors that will decrease their speed.

Gravity, friction, wind speed, and shape of the surface will also affect the spider’s climbing speed.
If you chase them, they can climb our walls quite fast, but if a building is high enough, then their speed can decrease as they reach more height.

They can be slow at climbing extreme heights, but they surely can climb it. Apart from all anatomical factors, it seems like spiders never give up.

If they are determined to climb something for a purpose, they will do no matter how many times they fail.


So, to formulate spiders can climb to a great height like high rising buildings, mountains, hills, very tall trees, etc. but they do it only when there are more food and low competition.
