Ever wondered how much food a spider eats? Or how to get rid of spiders in your home and business?

Here is a simple guide to everything you need to know about spiders, and how to dispose of them easily and safely.
Arachnids, known as spiders, have a distinct body shape, with a narrowed abdomen and modified fangs that secrete poison. They also possess two or more pairs of spinnerets, which they use to create webs and cocoons for their eggs.
  • Spiders have bodies divided into a cephalothorax and abdomen with eight joined legs.
  • Palps function as sensory organs and serve males in reproduction.
  • Upon moulting, spiders exit the exoskeleton by pulling the legs out.
  • Female spiders are usually larger than males.
  • There are seven types of spider glands to produce various silks (protein masses), but each spider species possess only a selection of glands.
  • By weight, spider dragline silk is 5x stronger than steel, 30% more flexible than nylon, 2x as elastic, and can absorb 3x the impact force of Kevlar.
  • Spider webs remain intact and undamaged despite exposure to microorganisms.
  • To allow moving from strand to strand and not sticking to webs, spiders have specific tarsal claws.
  • Spiders balloon by using strands of silk as a wing to ride on air currents.
  • Ground dwelling spiders line burrows with silk.
  • All spiders are predators.
  • Spiders that hunt have thick tufts of hair called scapulae on the bottom of their legs, which provide them with a large number of points of contact and enable them to move about on smooth, vertical surfaces and ceilings.
  • Spiders eat a weight of insects greater than the weight of the human population.
  • Most female spiders do not consume the male post-copulation.
  • Spiders consume by injecting a digestive fluid then suck up the fluid.
  • In the U.S., only 60 spider species are capable of biting. Of these, four are capable of causing injury. These are the Black Widow, Brown Recluse, Hobo, and Yellow Sac spiders.
  • Most spider fangs cannot penetrate human skin and are therefore harmless.
  • Most spider bites result only in localized swelling and/or irritation.
  • Spider problem or lighting problem? Change blue light fixtures to yellow (Hg vapor or blue light is 112x more attractive to insects than Na vapor or yellow light-fewer insects, fewer spiders).
  • Eliminate woodpiles, trash, rocks, and clutter or debris fields along exterior structural grade and foundation areas.
  • Maintain building positive pressure to push ballooning spiders out.
  • Seal or caulk cracks, crevices, and gaps as well as check to be sure doors and windows are serviceable.
  • Use pressure-washing systems as appropriate to eliminate heavy spider pressures.
  • Sweep away spider webs using a brush.
  • Manage interior excess moisture and relative humidify through vent and dehumidifier systems.
  • Vacuum (HEPA filter) webbing, egg sacks, spiders, and dead insects (place bag in sealed container for disposal).
  • Use appropriate glue traps to capture and monitor spider species and pressure.
  • Use professional products to reduce and eliminate spider pressures. For web-constructing spiders, lightly dust the web as it may be recycled biologically.
  • Always read, understand, and follow product label directions.
  • Communication throughout the process of spider management is critical and will establish realistic expectations for your customers.
