Occasionally, a spider bite can cause an allergic reaction. But while bites from some spiders like the venomous black widow and the brown recluse spider can be dangerous, most spider bites are harmless.

Keep in mind that spiders in general—and this includes the much-feared black widow and brown recluse-bite just in self-defense when they are trapped between your skin and another object. Steer clear of spiders: store firewood outside to avoid bringing spiders into the house. Install tight-fitting screens on your doors and windows, and seal off any cracks where spiders could enter. Make sure your attic and garage are free of spider webs. Discuss your fear of spiders with your loved ones and tell them you are getting treatment for your condition.
In southwestern America, spider was the creator goddess and weaving was an honored art. Spider was also credited with giving humanity the first alphabet; writing was equated with feminine wisdom. The Victorian view was more pragmatic, seeing the fly-eating spider as a part of the animal economy. In Hindu, spider sitting in its web watching till its prey is entangled represents being caught in the illusion of the physical world. Despite their diversity, all spiders have the eight fragile legs.
Spider bodies are split into two sections. Most, but not all, are weavers.
All About Spider Mites | Just For Growers
All spiders are predatory and nearly all are venomous. Most weave a deadly trap in the form of a web.
Females are usually larger than males. Procreation typically means death for the mail. Spiders are good mothers and stay with their eggs until they hatch. Some carry the eggs on their bodies until they hatch.
One spider commonly found in English gardens lets her young prey upon her body — the ultimate sacrifice. Spider must shed its skin in order to grow, much like the snake. Spider and snake are remarkably similar in symbolism. Spider is creator; she is death. On a Freudian level spider embodies woman. She is the creative force, weaving the designs of life and fate. Spider is associated with words and communication. Spider bestows the power to work magic over people and things.
By weaving, it gains a certain element of control; once the prey is wrapped up, this control is complete. Some find the eight legs and body shape in the form of an eight significant; numerology equates spider with the symbol for infinity.

But it doesn't stop there. The moisture stress caused by spider mite feeding actually makes the leaves taste better to the mites! Stressed leaves are sweeter and contain higher levels of soluble nitrogen. Both sugar and nitrogen are sought-after delicacies on the spider mite's menu. Novice growers are continually astounded that something so small can wreak such a huge amount of havoc.
Yes, spider mites are small-really, really small. They are mere specks when seen crawling on the undersurface of leaves.
Why Don’t Spiders Get Caught in Their Webs?
Under a microscope they appear to have two occasionally four black spots. Young mites are six-legged. After two periods of molting and resting, they become adults and have eight legs. Generations may be completed in 5 to 40 days. If you don't own a jeweler's loupe, you should consider buying one. They are fairly inexpensive. Spider mites are so tiny that they can float in on a breeze! They can therefore easily migrate from other plants that you may have in your house to your indoor garden.
Mites will go dormant, even when pregnant. They will hitch a ride on your shoes and clothes and on your pets. Savvy growers cover all air intakes with a bug screen. Often you can buy these at your local indoor gardening store, or you can fashion one yourself with an ultra-fine mesh silkscreen or stainless steel screen.
Just make sure it is microns or less. If you don't take this into account you will cut down your CFMs of airflow and up the static pressure of your room's air handling system s. I usually like to oversize and go four times bigger than the ductwork for the micron screened vent penetration. There are so many different approaches and philosophies when it comes to pest management, with some growers invariably being willing to resort to more extreme measures than others. Obviously, as with all pests, prevention is better than cure. But tell that to somebody who's just discovered an infestation and this little gem of wisdom is not likely to be greeted very philosophically.
The choice of product you use also depends on where your plants are in terms of their lifecycle. One product that is good for vegetative plants may not be advisable to use if your plants are heavily flowering. If you are a couple weeks away from harvest, even if you have the serious infestation and have the web thing going on, knock the bugs down with cold water and finish the crop.
WHAT YOU NEED TO KNOW:
Some studies have even shown increased yields with moderate levels of insect stress. Spider mites thrive in hot, dry conditions. Cooler, more humid conditions slow reproductive rates considerably. Outdoors, spider mites are active in the spring and go dormant over winter.
