Also, homes within the Phoenix area provide shelter and food that black widows thrive on, making them a prevalent and dangerous pest in our area. Black Widows are commonly found in low to the ground places, including home foundations, corners, plant bases, and perimeter block walls. Black Widows are also sometimes found in children’s sandboxes and play equipment, or woodpiles and shrubs. A Black Widow reproduces in the summer months, producing up to 9 egg sacks each containing up to 400 spiderlings.Black Widows are not inherently aggressive spiders. However, because they actively hide in dark, low to the ground places, Black Widows are frequently undetected until a bite occurs, usually by an unaware person who steps into a nesting area. Female Black Widows are the spiders with the venomous bite. The initial bite may be painful, but as the venom spreads through the human body, it can cause extreme pain. Generally, the Black Widow’s venom is not fatal for most people, thought the very young, elderly, or those with compromised immune systems may be at serious risk. It is important for anyone that suspects they’ve been bitten by a black widow to seek immediate medical attention, regardless of age or medical history.Because they can be very dangerous, if you discover or suspect that Black Widows are nesting in or around your home, it is important to call a reputable exterminator right away.Desert Recluse SpidersDesert Recluse Spiders are another common Arizona spider species. Desert Recluses are generally smaller than an inch and light to medium brown in color. Desert recluse spiders lay several egg sacs every summer and produce up to 50 eggs per sac. Desert Recluse Spiders are extremely resilient and suited to desert living as they can tolerate up to six months of drought. Like the Black Widow, the Desert Recluse tries to avoid conflict and usually flees.Desert Recluse Spiders favor dry and undisturbed spaces to build their webs, including woodpiles, closets and garages. They can sometimes be found in cardboard and other dark, warm spaces inside homes. $50 Off Your Initial Service CALL NOW GET QUOTEOffer valid when you start any Blue Sky 365 programThough there bites are venomous, Desert Recluse Spider bites are rare, and are generally reported from events such as putting on clothing that hasn’t been worn recently.
