How do bugs walk up walls?

Certain insects have specialized feet that enable them to defy gravity and walk in places that seem to be impossible to cling to. Stiff hairs, natural adhesives and large claws all come into play to enable the insect to walk on smooth, upright or upside-down surfaces.

How do spiders climb on walls?

The scientists found that the spider’s legs contain a tuft of hairs, and that each individual hair in the tuft is covered by hundreds of thousands of smaller hairs – called setules – just hundreds of nanometres in width. The spider uses these setules to stick to surfaces (see figure 2).

Can house spiders climb walls?

At dusk they leave the dark corners and recesses where they build their webs, running across open ground, climbing walls and even running over roof tops. Once they have put a bit of distance between them and their web they now look again for dark corners and recesses where the web of a female may be found.

How do insects stick to surfaces?

But in some cases, insects do make use of a kind of adhesion. If the surface is smooth, the insect can hold on using the adhesive action of hairs located on sticky pads (known as the arolia or pulvilli) on the tarsi.

Why do spiders have paddles on their feet?

They look a little bit like paddles on the ends of stalks, and they give the spider a much bigger surface area. When the feet make contact with a wall or ceiling, they create a force – a temporary attraction between the bottom of the spider’s foot and whatever surface it’s on (the grown-up name for it is van der Waals forces).
