Brown Widow Spider–Shy but Dangerous!

Brown Widow Spider Quick Facts
Is It a Brown Widow Spider? – Identifying a Brown Widow Spider
Unlike its starkly black-and-red colored relative, the black widow, the coloration of a brown widow consists of mottling of tan and brown with black accent marking. In mature females, there is usually a dorsal longitudinal abdominal stripe and three diagonal stripes on each flank. At the top of each diagonal stripe, there is a black mark, which is rather conspicuous and square-ish. The Brown Widow Spider does have an hourglass, but it is typically an orange shade rather than the vivid red of a black widow. The brown widow looks similar to immatures of the western black widow spider, the latter of which has smaller black spots on the top of the diagonal abdominal stripes and more olive-grey background coloration.
Where Do Brown Widow Spiders Live? — Habitat of Brown Widow Spiders
The brown widow builds its web in secluded, protected sites around homes, and woody vegetation with branches. Some typical sites selected by brown widows for web building are empty containers such as buckets and nursery pots, mailboxes, entryway corners, under eaves, storage closets and garages, recessed hand grips of plastic garbage cans, undercarriages of motor vehicles that are stationary for long periods, and the undersides of outdoor furniture and wrought-iron railings. They choose places that are more exposed than sites chosen by black widows and hence, appear to be at higher risk for interactions with humans as bites are concerned.
How Do Brown Widow Spiders behave? — The Lifestyle of Brown Widow Spiders
As of 2012, researchers at the University of California, Riverside, suggested that the brown widow spider, newly established in Southern California, maybe displacing black widow spiders from the region, competing and/or fighting for territory. While certainly not definitive, this evidence does suggest that the brown widow is likely to be more hostile and aggressive towards its relative, the black widow, than the black widow is towards it. If that proves to be true, humans may be positively affected since brown widow bites are less toxic than those of black widows, thus posing less of a threat as they displace black widows over time.
Life Cycle of The Brown Recluse Spider
Spiders have three stages in their life cycle: egg, spiderling, and adult. After mating, the female lays about 80 eggs and surrounds them with thick silk to build an egg sac. A few days later, the spiderlings hatch from the eggs. They feed on insects trapped in the web and on each other. As spiderlings eat and mature, they outgrow their skin, grow a new skin layer, and shed the old one, a process called molting. Spiders molt throughout their lives. Spiders can reproduce once they reach adult size. Female brown widows reproduce continuously and can make about 20 egg sacs over her lifetime. The web often has several eggs sacs of different ages, developing at the same time. The egg sac of the brown widow has spiny protrusions, compared to the smooth egg sac of the black widow.
How to Tell if I have Brown Widow Spiders? — Brown Widow Spider Infestation
The webs of brown and black widow spiders are made from sticky silken fibers, irregularly shaped, tangled, and constructed in hidden and protected locations. The webs can be found in dense woody plants, in empty containers, under buckets and pots, mailboxes, and under outdoor furniture. They are usually not found inside buildings. They choose more exposed sites than those chosen by black widows, which may increase their interactions with humans. A sighting of the spider is an indication of an infestation.
Are Brown Widow Spiders dangerous? — Threats of Brown Widow Spider Infestation
Brown widow bites have a milder effect than black widows, possibly because the brown widow does not have or cannot inject as much venom as its larger relative. Symptoms of a brown widow bite are similar to most spider bites: pain at the bite site and a red mark. Although its venom is as potent as black widow venom, the brown widow probably doesn’t inject very much venom, making it much less dangerous. Brown widows are shy and tend to avoid contact with humans. Females are not aggressive, make no effort to attack, and prefer to retreat or lie perfectly still. When confronted or provoked, however, they will bite. If bitten, place a cold pack on the bite to relieve the pain and seek medical attention immediately.
