- Thorough inspection of the building is essential and may have to be made at night
- Identification is important for pest management and medical reasons
- The key to control is the timely mechanical removal of spiders, webs, but especially the egg sacs with a vacuum, both inside and outside. Seal and dispose of the bag immediately.
- Spiders are found everywhere (except Antartica)
- They are established in nearly every habititat (except for air and sea)
- All spiders are predators, feeding mainly on insects and other small arthropods
- They capture their prey in sticky webs, paralyzing or killing with venom
- Can survive without food for several weeks to a few months
- In the U.S. only 2 spider groups are considered dangerous to man (widow spiders and recluse spiders)
CHARACTERISTIC OF SPIDERS
- Arthropods having eight legs and fangs that inject venom
- 2 body regions (head and thorax). abdomen connected by a tiny waist.
- Atennae absent
- Fangs, connected internally to a poison duct.
- Slender legs, 4 pair
- Males usually smaller than females
- In a week or more after mating, the female deposits 20 to several hundred eggs in a silken sac
- It may be weeks later, or not until the following spring before the spiderlings hatch and/or emerge from the sac
- Spiderlings go through 4 to 12 molts before maturity
- Most spiders live for 1 or 2 seasons
- Most spiders are nocturnal or active at night and will scurry away when disturbed unless they are tending egg sacs or young
- During the day, they usually remain hidden and inactive in cracks and crevices, their webs, etc.
- BItes usually occur when males are seraching for females, or when people clean out neglected places such as basements, attics, garages, or put on seldom-used clothing
