INTERESTING FACTS ABOUT SPIDERS
In honor of Halloween, we thought it necessary to cover one of the creepy crawlers most associated with Halloween… Spiders! Spiders are found just about everywhere and have adapted to live in nearly every type of habitat. They are actually one of the top 10 most diverse populations on earth today. While they do play a vital role in the ecosystem, there is no role for them in your home. The following spider facts are fun and interesting to know, but it is important to implement a consistent pest control treatment to keep these critters out of your house. Learn everything you ever wanted to know about spiders but were too terrified to ask!
Spiders are not actually insects.
Many people think that spiders are insects, but in fact, they are not. Spiders belong to a different biological group called arachnids. One major difference between insects and arachnids include insects having 3 body parts (head, thorax, and abdomen) while arachnids only have 2 (head and abdomen). Arachnids do not have antennae and never have wings. Also, insects have six legs and only two eyes versus an arachnid’s eight legs and up to eight eyes.
Females can lay up to 3,000 eggs at one time.
Spider eggs are housed in one or more silk sacs. It varies by species as to the level of care a female spider will provide to her young. Some females will die shortly after laying eggs while others will carry babies on their backs or share prey with them.
Jumping spiders can jump up to 50x their own length.
Jumping spiders are able to make agile movements and jump multiple times their body length when hunting or attempting to escape a predator. Jumping spiders have an internal hydraulic system that makes this possible. Using this hydraulic, they can alter the pressure of fluids in their legs resulting in a motion that propels them forward.
All spiders spin silk.
Something common to all 40,000 species of spiders is that they all spin silk. With that said, all spiders do spin silk, but not all spiders spin webs. Every species of spider has a special gland known as a spinneret that is usually on the lower back. The threads produced are light and thin but surprisingly strong. For its weight, spider web silk is actually stronger and tougher than steel.
Some species can see spectrums of light.
Certain species of spiders can actually see into spectrums that we humans cannot. A few types of spiders have been known to be able to see both UVA and UVB light.
Spider skeletons are on the outside of their body.
Spiders are among the many species to have what is known as an exoskeleton. Much like crabs, the hard and supportive parts of spider’s body structure – the skeleton – are located on the outside of their bodies. The exoskeleton not only provides support, but it also provides protection by encasing the spider’s vital organs in a shielding outer shell. In order to grow, spiders undergo a “molt” and sheds its old exoskeleton before a new one hardens around it.
Many spiders will die after mating.
Most spiders only live for about 1 year, and some may not even live that long. Many species will die once they have successfully reproduced. In the wild, they are subject to diseases, predators, and accidents which lower their chances of reaching genetic old age. Most spiders won’t live beyond two or three years, but in the protection of captivity with optimum nutrition and expert care, a few Tarantulas have lived up to 35 years old!
Most spiders are not poisonous to humans.
While almost all spiders kill their prey by using poison-producing fangs, the majority of spiders are not actually poisonous to humans. A few types of spiders can be deadly to humans though, such as the Black Widow, Brown Recluse, and other bird-eating spiders.
Some people even eat spiders!
Yes, it’s true. In some parts of the world, people actually eat spiders. As it seems like a nauseating idea to most, many parts of East Asian countries consider it a quite normal component in their cuisine. In Cambodia, an edible Tarantula species is being farmed. It is usually eaten fried in oil as a tasty and crunchy snack!
As mentioned, spiders are quite interesting creatures but many would still like to avoid them in their home! Contact the professionals at Black Diamond if you notice signs of a spider infestation this Halloween season. And no – we are not talking about the ones of decoration variety!
