Great Questions from Kids : Spider Webs, Mosquito bites, Bed Bugs and more!

happy spider Eco Bug DoctorKids ask great questions, that's a fact! Here's the Eco Bug Doctor's answers to some curious questions.


  • Do all spiders make webs? 

While the majority of spiders make webs for capturing prey, there are some that don’t. Some spiders that do not make typical webs include species of jumping spiders, tarantulas, wolf spiders, among others. The wolf spider, for example, instead of catching his prey in a web will tend to hunt its prey and pounce on it, or even chase after it. But all spiders make silk. Spiders have many different uses for the silk they produce, and, depending of the species of spider, silk could be used for: weaving webs to catch prey, making a parachute, protecting eggs, making a love web, and many other things.


  • What would happen if we just got rid of all the bugs in the world?

Out of all the species of animals in the world, over 75% are insects. So we could imagine their disappearance would have a tremendous impact on the world as we know it. Insects are an important and essential part of the world’s ecosystems. They pollinate plants that produce fruits and vegetables, they recycle organic matter, aerate the soil, and serve as food for many other animals. Without them, fruits and many vegetables would not form. Also, all kinds of organic matter such as dead trees, plants, and animals would lie around without insects to help them decompose. Insect-derived products such as honey, silk and beeswax would no longer be available. Finally, many animals that feed on insects, like some species of birds (ex. warblers and robins), lizards, mammals (ex. bats and hedgehogs) and fish could disappear.


  • Do bed bugs really live in my bed?

Inside a home that is infested with bed bugs, the bed is the most common place to find them. There are many species of bed bugs, and all of them feed only on the blood of warm-blooded animals such as bats, birds, and us humans. The term bed bug is usually used to refer to the bed bug species that feed on humans. As the name implies, in a house, they can be found in a bed or surrounding areas. They will usually be found in cracks and crevasses close to a place where a person sleeps. After night falls, they crawl out of their hiding places and find their host to begin feeding.


  • Why do mosquito bites itch?

The itching actually comes from your body`s reaction to the saliva that the mosquito injects when she is feeding on your blood. When a mosquito lands on you, she will begin to feed by piercing your skin with a straw-like mouthpart, called a proboscis, which she uses to find a blood vessel. Once she has hit a blood vessel, she will inject saliva into the wound. Her saliva contains anti-coagulants, which keep the blood flowing so that she can drink a good meal. Your immune system reacts to the mosquito`s saliva and tries to fight it by sending histamines, which cause your blood vessels to swell around the mosquito bite. The swelling of your blood vessels irritates the surrounding nerves—and this is what creates that itching sensation.
