- House spiders play an important role. Spiders are opportunistic eaters and will feed on as many insects as they can catch in one short period. That means there will be weeks when the insect population in their part of the world is small, so the spiders have no opportunities to feed for a while. Because they are poikilothermic (cold-blooded) and inactive for much of each day this temporary loss of a food supply is not a problem. However, prolonged periods of enforced starvation will ultimately lead to death.
- Killing a spider makes the spider genetic pool sneakier and more deadly.
While you may be killing the spiders that are in the wide open, you are allowing the other ones that hide in the shadows to propagate and make smaller deadlier babies to roam around. Mainly you are teaching them how to be sneakier.
- Spiders can walk on other species of spider webs.
Spiders have the ability to walk on other species of spider webs without any problem. Spiders can navigate webs via two distinct mechanisms. The first method of navigation involves prior knowledge of which strands of the web are “sticky” and which are not. The second method of web navigation involves grasping the sticky strands of the web with specialized structures on the leg tips.

- If you get a bite from a Black Window, it doesn’t mean you will die.
A bite from a Black Widow has notoriously interpreted by many and painful and grueling death, but that might not be as accurate as most belief. Wiki states, these symptoms, “Pain, muscle rigidity, vomiting, and sweating are the hallmarks of latrodectism.

- Most people are afraid of spiders, but why?
Your freeze flight or fight instinct doesn’t distinguish the thing you see consciously. Spiders are a combination of fear triggers: long and angular legs, dark colors, darting and erratic movement. Your amygdala noticed those little things and went “this is fast, I can’t predict it, I don’t know what it is, get ready.” The amygdala also plays a role in associating emotion with memory and fear gets a prominent attachment, so people can feel uneasy just looking at a picture of a spider.
