Two Reasons Why Winter Bark Scorpion Control Is a Must February 8, 2022 - By: Bob Gilbert, Board Certified Entomologist As temperatures fall, pest activities drop in kind…including scorpion activity. With decreased activity, it’s easy to adopt an ‘out of sight, out of mind’ attitude. However, skipping bark scorpion control during winter months results in missing one of the most opportune times to treat.Keep reading to find out some interesting facts about the Arizona bark scorpion and the two reasons why winter scorpion control is a must.Arizona Bark Scorpion: The BasicsAt just over 3 inches, the Arizona bark scorpion is the only scorpion in the United States considered life threatening to humans. While stings are rarely fatal, they do cause extreme pain and medical attention is advised for pets, young children, elderly, and those with chronic medical conditions.Related: How to Avoid Scorpion StingsArizona bark scorpions are found throughout the Phoenix metropolitan area. They prefer riparian areas, but the explosive growth in the valley, and corresponding landscape and irrigation systems, have provided favorable conditions for bark scorpions to adapt to the urban environment.Having survived months of being frozen and even showing no adverse effects after being found near ground zero of nuclear testing sites, the Arizona bark scorpion is incredibly resilient.In addition to being resilient, and unlike most scorpions, Arizona bark scorpions are excellent climbers. Combine their climbing skills with their ability to fit into spaces as small as 1/16th of an inch, and it is easy to see why bark scorpions are often found as uninvited guests within homes.While the Arizona bark scorpion is incredibly adaptable and resilient, proper treatment can keep them under control. Let’s jump into why proper treatment during winter months is especially important.Reason 1: Winter GatheringAs temperatures decrease and daylight hours get shorter, scorpions gather in groups seeking safe haven in hidden places. In addition, Arizona bark scorpions enter diapause, a state of lower to no activity brought on by unfavorable environmental conditions, namely colder temperatures. They will stay in diapause until nighttime temperatures average 73°F or above.Related: Winter Time Scorpion Control in ArizonaSo, during winter months, Arizona bark scorpions are gathered together in a state of minimal activity, thus increasing the effectiveness of proper scorpion treatment.Reason 2: Mating ActivityThe other reason winter treatment is a must revolves around the Arizona bark scorpions’ mating activities. Often mating in the fall, female bark scorpions have a gestation period throughout the winter months. As weather warms, the resulting litters range from 25-35 young scorpions contributing to increased activity in the spring.Thus, proper winter scorpion treatment, during the gestation period, minimizes the next generation of bark scorpions before they become a problem.RecapAs mentioned previously, colder winter months result in little to no scorpion activity, but it is the opportune time to apply the proper bark scorpion treatment because…Scorpions are gathered together in a lethargic state (diapause) compounding the effects of proper treatment.Addressing bark scorpions during the gestation period reduces the next wave of scorpions before they are born.Why Blue SkyBeing an Arizona owned company, with a technical management team with over 100 years of Arizona pest experience, and technicians with at least 100 hours of training, we have the know how to keep your Arizona home scorpion and pest free.
