Spiders are one of the most commonly sighted household pests in Australia. Though they are usually considered a nuisance and stuff of nightmares by many, these eight-legged creatures are actually quite intriguing. Let’s have a look at some interesting facts about them:

1. The body of a spider can be divided into two parts: the abdomen and the cephalothorax. In the abdomen reside the spinnerets. In the cephalothorax region, there are the eyes, palps, legs and fangs.

2. Spiders are congential predators: Spiders hunt for capturing prey. Majority of spiders eat other insects and invertebrates. However, some large spiders even prey on vertebrates like birds.

3. Spiders don’t consume solid foods: Spiders turn their food into a fluid form, before eating it. They discharge digestive enzymes from their stomach into the victim’s body.

4. All spiders can produce silk: All spiders can make silk throughout their entire lifetime. They use silk for capturing prey, protecting their offsprings, shelter, and reproducing. But all spiders do not use slik in the similar way.

5. Not all spiders spin webs: Some spiders do not need webs like the wolf spiders, who overtake and stalk their prey without web. Jumping spiders have good eyesight and can move very quickly, therefore, they do not require web.

6. Males risk being eaten by their female mates: Since female spiders are usually larger compared to their female peers, the former often put themselves at the risk of being eaten by the latter while mating. This is because a hungry female arachnid would eat any invertebrate coming in her way, even her suitors.

7. Spiders use silk for protecting their eggs: A female spider deposits her eggs on a silk bed. After producing the eggs, she protects them by covering with more silk. Cobweb spiders use a thick, watertight egg sac, whereas celler spiders use minimum silk for encasing their eggs.

8. Spiders don’t just move using their muscles: Spiders need haemolymph pressure as well as muscles for moving their legs. By contracting muscles in cephalothorax, they increase the hemolymph pressure in their legs.

9. Spiders can see what we can’t:- Some species, such as the jumping spiders, are capable of looking into spectrums that we humans can’t. A few can even see UVA as well as UVB light.

10. Spider webs are stronger than steel:- The silk produced by arachnids is much tougher and stronger than steel, when compared in same quantities.

Even though all of these sound very interesting, you cannot ignore the fact that spiders must be controlled with the help of professional pest management services. Therefore, if you ever encounter one of them in your house in North Shore, contact pest control experts immediately.
