Spider Behavior
There are thousands of different types, sizes and colors of spiders found all over the world in nearly every type of habitat. Spiders rarely bite humans unless their nests or webs are disturbed. With the exception of a few species, the venom in spider bites is harmless to humans, but some individuals may be hypersensitive and can have a mild to severe allergic reaction when bitten. Spiders feed primarily on other insects, but larger species have been known to feed on small animals such as lizards, birds and millipedes. Spiders in your home can be a sign of a larger pest infestation, and their building of webs indoors can prove to be a nuisance for most homeowners when left untreated. The combination of good sanitation practices and a comprehensive pest control treatment program are necessary to eliminating spiders inside the home.
Spiders have fangs that inject venom in their prey, but usually the venom is harmless to humans when bitten. Spiders are considered predators, they eat other insects, small lizards and baby birds. Spiders do not have chewing mouth parts and rely on digestive enzymes found in their saliva to break down their food. Not all species utilize their webs to trap their prey and some species do not spin webs at all.
Most spiders have a life span of one year, although species such as the Tarantula can live as long as twenty years. The number of offspring spiders produce depends on the species. On average, a female spider can produce 4-300 eggs per sac and can carry up to nine egg sacs a season (breeding cycle). Young spiders, also known as spiderlings, emerge from the egg sac and disperse in a process called ballooning in which they are carried away by the wind after climbing onto nearby objects. This method of dispersal means spiders often can easily recolonize an area where they had previously been eliminated.
Male spiders are often dramatically smaller than their female counterparts. Male spiders are more commonly found in homes as they tend to wander indoors in search of females during mating season. Males are identified by the presence of an enlarged mouthparts (or pulps) that are used to transfer sperm. Although spiders are often feared or considered a nuisance, spiders play a unique role in the biological control of other insects. Spiders found inside the home are often a sign of a larger pest infestation and proper treatment and sanitation methods should be used to ensure control.
