Spider Control | Utah
Spiders are one of the most feared invaders in Utah homes. More Utah homeowners have a bigger phobia with spiders than any other pest, and perhaps for good reason. If bitten by the wrong spider such as a Black Widow, Hobo, or Brown Recluse and if you have a bad reaction to the venom, a person can get very sick, and yes, in extremely rare cases death can occur.
Most spiders have toxic venom, which they use to immobilize and kill their prey. However, only those spiders that cause a serious reaction in humans are considered “poisonous spiders”. Most spider bites result in no more than a slight swelling, inflammation, or itching sensation. The feared Black Widow spider is considered the most venomous spider in Utah. However, the female injects such a small dose of venom that it rarely causes death. Reports indicate human mortality at well less than 1% from Black Widow spider bites.
The Hobo spider is also a common spider in Utah. Hobo spiders have been reported to have a bite that causes a necrotic (i.e., rotting flesh) wound that progresses over several days – similar to that of a Brown Recluse spider bite. Other symptoms of a Hobo spider bite is a headache that can persist for up to 7 days and does not abate with analgesics (pain relievers). The Brown Recluse spider has not taken root here in Utah according to Utah State University Extension Service.
Some spiders prefer dark moist locations such as basements, crawl spaces and other damp areas. Others prefer dry warm areas such as the sub flooring in homes and buildings, upper corners in rooms and attics. Some spiders are active hunters and move around a lot in search of prey (these spiders are much easier to eradicate because they generally come in contact with treated areas very quickly). Other spiders prefer to “lie in wait” and capture their prey (trapping their prey in webs). These spiders take a little longer to eradicate because they don’t move around much. Once their food source dries up from the treatment, they will begin to move… once they start moving – they will come in contact with treated areas. For this reason, it’s not uncommon to see activity again after a two or three week lull.
Young spiders spread using a process called ballooning. These young spiders, often referred to as spiderlings, emerge from egg sacs and disperse. Many climb to the top of a nearby object, produce filaments of silk (known as gossamer), and become carried away by the wind. Spiderlings can be carried long distances using this method.
