Insects destroy about one-third of our crop yields every year.

Insects outnumber humans by a 200,000,000:1 ratio.

In a woodland or forest, a single acre harbors more insects than there are human beings on the entire planet.

Every fourth creature on this planet is a beetle.

A single tree in the rainforest can harbor hundreds of species of beetle, many of which have not yet been discovered.

There are about 34,000 known species of spider in the world. Entomologists believe this at best only half the species that actually exist since new species are discovered in the rainforests every year.

20 spiders per square meter in a farm field can reduce crop-destroying insects by 90% (of course they might also eat bees). Spiders are the single most important insectivore on this planet and consume hundreds of tons of them a year. Without spiders, we would be doomed and would drown in insects within a few months by which time they would blanket the earth several times over.

Black widow venom is 10 times more powerful than rattlesnake venom.

Spiders are so perfectly evolved that some have taken to the water without the need to develop paddles or gills. They can even store air bubbles underwater in silk mats that they spin and use those to breathe and remain submerged longer.

Brown Recluse spiders often carry the "flesh-eating" bacteria that necrotizes living flesh causing very shocking wounds on people unfortunate enough to be bitten by them.

Spiders have almost no muscles. So they can sit motionless for days at a time waiting for a meal to walk or fly by and then snatch it lightning quick. They don't need to "stretch". They also have no bones but rather an exoskeleton.

Daddy-long-legs are not super venomous as per the myth. They are essentially harmless to humans.

How many spiders do you eat in your sleep? None. It's an internet myth started by some smart-ass. No one has done any research on this. If a spider or any insect tried to crawl down your throat your automatic gag reflex would reject it and awaken you. You do eat insects without knowing it--or rather, you eat insect parts because they are in your food. There is no way to keep them out so the govt has guidelines concerning how many bug and spider parts are allowed in a serving of food.

If possible, it is best to leave spiders alone if you find them in your house as they eat insects you don't want to run into. A large population of spiders in your house also means you have a huge bug problem.   

Mexican red-leg tarantulas have been over-harvested by the exotic pet trade and are now endangered. Don't buy them.
