Spider Life Cycle

Spider belongs to the class of Arachnids. They have eight legs and mouthpart called chelicerae which injects the venom to their prey. There are spiders worldwide and have at least 109 families identified by taxonomists. Antarctica is the only known continent with no registered spider on site.

Female spiders would lay their eggs in an egg sac. You can distinguish the type of spider based on how their egg sac would look like. These eggs would only take a few weeks to develop and hatch. Once hatch, spiderlings would disperse. Some would follow the process of ballooning in which the spiderling would climb up a grass blade or branch to be release a wisp of silk. The wind will pick up the silk and carry the spider across. Spiderlings can be carried within few feet to hundreds of miles. Therefore, spiders can colonize a remote area without prior generations. Spiderlings molt to reach their adult phase. Some spiders molt throughout their lives. Both male and female spiders have spinnerets that are responsible for their web spinning.

Female spiders are fertilized when male spiders deposit into the female’s reproductive opening. Male spiders release their sperm in a sperm web and hold it in their palps before depositing to the female spider. Male courtship varies across species. Courtship rituals exist to avoid being eaten by the females. Once sperm has been deposited, eggs are fertilized in just a few weeks then laid into the egg sacs. The amount of egg sacs laid by the female spider depends on their species.

Common House Spiders

While there are numerous spiders found across the globe, only a few would be found in urban setting. However, note that spiders are resilient and adaptable so they can thrive once introduced to a certain environment. Here are the common reported spiders found in houses.

Brown Recluse Spider

One of the most common spiders found in American homes is the brown recluse spider. It is also known as the violin spider because of its distinguishing mark shaped like a violin on its neck. This spider can be between 6-20 mm in size, but may also be bigger. Other names of the brown recluse spider include fiddleback spider or brown fiddler. Another distinguishing feature of this spider is having six eyes arranged in pairs compared to most spiders with eight eyes. There will appear to be soft fur if you magnify their abdomens that are covered with fine short hairs.

The brown recluse spider is considered as one of the dangerous spiders in the United States. They are native to southern states such as central Texas and western Georgia. They are also known to be inhabitants in southeastern Nebraska. They build irregular webs as habitat. Their webs can be found in closets, garages, woodpiles, and sheds. They prefer dry and undisturbed places. Therefore, there have been encounters with the brown recluse spider in stocked shoes and stored clothes. Even bed sheets of unused beds can be inhabited by these spiders. These spiders are nocturnal hunters. Their diet consists of crickets, cockroaches, ants, and other soft-bodied insects. Make sure you avoid being infested by these spiders. There had been a case back in 2001 where one Kansas home has spider infestation of 2,000 brown recluse spiders. Imagine seeing all those spiders during spider extermination.

These spiders can bite you however they are rarely aggressive. They have tiny fangs which cannot penetrate majority of human fabric. Cases of spider bites from the brown recluse spider are reported when wearing clothes that have been left on the floor for days. However, a brown recluse spider bite can be painful and lead to life-threatening complications. It has hemotoxic venom that can be fatal. Some bites have shown to lead to skin necrosis and some rare cases had lead to bursting of red blood cells. Most bites would not show symptoms but will become painful and itchy within the next 2 to 8 hours. It is important to have this diagnosed as 80% of reported brown recluse bites have been misdiagnosed. Better if you are able to capture the spider for identification.

Brown Widow Spider

The brown widow spider also goes by grey widow, house button spider or geometric button spider. It is considered as a “cousin” of the infamous black widow as they share the same genus. They are originally from South Africa but had been found in many areas in the United States since 1935. They have lighter color compared to the black widow species. Their color can be from tan to dark brown and has a distinguishing glass-shaped marking on their abdomen. The hourglass would usually be vivid orange or yellow. Their legs are usually stripe. Brown widow spiders would usually measure around 38mm.

Egg sacs of brown widows can easily be found and identified. These sacs appear to be tan and spiked. These eggs would hatch within 20 days and has around 120-150 eggs. A female brown widow can produce 20 egg sacs in her lifetime.

The brown widow spider can be considered as an urban dweller. You can find them living in wood piles, storage sheds, cabinets, furniture, and even abandoned vehicles. They can also be found hiding behind your window shutters and inside your shoes.

The venom of brown widows is comparable to the black widow but brown widow bites are not as dangerous as that of a black widow. Brown widow bites do not deliver as much venom as the black widow. They prey on flies, mosquitoes, grasshoppers, caterpillars, centipedes, beetles, and other spiders. Brown widow spider bites can be removed from your system naturally without having serious effect. However, it can be more critical for infants and older adults. There can be numbing and abdominal muscle cramps within 24 hours.

Black Widow

Next to the brown recluse spider, the black widow can be a threat to your area. The term black widow refers to several spiders known to devour the male of the species after copulation. Compared to the brown widow spiders, black widows have red hourglass-shaped mark on their abdomen.

A black widow’s bite can cause muscle aches, nausea, and difficulty in breathing. However, black widow bites are not fatal to humans. Black widows will suspend a spun cocoon that contains hundreds of eggs. Spiderlings will leave the cocoon but the web will remain. The spun web is also used to catch their prey such as grasshoppers, caterpillars, beetles and flies.

Hobo Spider

The Hobo Spider is not a native of America but had been introduced through transportation from Europe. They have V-shaped patterns on their abdomen and a light stripe running down the middle of their sternum. These spiders are known to create funnel-shaped webs. They hunt for their prey by staying at the small end of the funnel and wait for insects to enter. The hobo spider would usually run away at the sight of humans but can be aggressive when their egg sacs are threatened. They are considered as a dangerous species based on their venom. Some bites attributed to brown recluse spiders are actually caused by hobo spiders. They are both known to cause necrosis in humans but more confirmed cases are needed for scientific study.

American Grass Spider

The American grass spiders build non-sticky webs with funnel shelter at one edge. They are relatively rapid spiders that make up for their non-sticky webs. The American grass spiders have eights eyes arranged in three rows. These spiders produce agatoxins that leads to rapid paralysis on their prey when bitten. However, their mouthparts are too small to insert venom in a human skin.
