Spiders have simple development because they undergo very little in terms of metamorphosis.

Essentially, newly hatched spiderlings look like miniature adults.

As arthropods, spiders have an exoskeleton. Because exoskeletons dont stretch, spiders must molt (shed their exoskeleton) to increase in size. Throughout its lifetime, a spider will undergo several molts.

The lifespan of a spider is about 1-2 years on average. An exception to this includes larger spider species, such as the tarantula, who can live up to 20 years.

Spider lifecycles begin when spiders lay their eggs, wrapping them in specialized protective cases made of silk. Within these egg sacs, spiders will develop until they are ready to hatch, which could take anywhere from a week to several months. A single egg sac may contain 50-100 eggs or more.

Once the eggs hatch, the spiderlings will remain inside of the silken sac and undergo their first molt.

When mature spiderlings are ready to emerge from their egg sac, they use their chelicerae (mouthparts) to tear the sac open. Once they emerge, spiderlings will initially stay in close proximity to one another.

Eventually, the spiderlings will disperse to new areas, using a technique called ballooning. Ballooning occurs when spiderlings release a single strand of webbing that eventually catches an air current and lifts and blows the tiny spiders virtually anywhere.

With millions of small spiders riding air currents in the early part of the season, inevitably some spiders will end up being blown onto and into buildings. Building located near a good spider habitats, will be more likely to have problems associated with spiders.
