“…The increase in the number of cases of scorpionism occurs due to factors such as lack of sanitation and poor housing conditions, especially in the big cities, with two factors being indicated as the main causes of the occurrence of these animals: 1 -urban environments offer hideaway, places that are difficult to access for man and natural predators, making biological control impossible; 2 -the accumulation of garbage in cities brings roaches and other insects that are abundant food sources for spiders and scorpions (Stropa, 2010).…”

Scorpionic accidents are a major public health problem due to the high occurrence with potential seriousness. In this manner, the research aimed to analyze the occurrence of scorpionic accidents in a municipality in the northeastern of Brazil. An exploratory, descriptive study was made, with a quantitative approach, using secondary data which was gotten from the Notifiable Diseases Information System (SINAN), from 2008 to 2018. Data such as neighborhood, presence of street markets were also used, and the existence of sanitation and climatic data such as temperature and season. Geoprocessing was used to identify possible changes in the environment. In the analyzed period, 9,330 cases of scorpion accidents were recorded, with an average of 848 annual notifications. Scorpionic accidents occurred more frequently in women (5,686; 60.94%). Individuals aged 20 to 29 years (1.727; 18.51%) were more frequent to scorpion stings. Regarding the body parts where the stings were made, the highlights were on the foot (3.515; 37.67%) followed by the hand (2.818; 30.20%). No statistically significant relation was observed between climatic factors and scorpionic accidents. However, the high number of cases of scorpionic accidents was observed in the last 11 years studied. It was evident that during the study period there was no statistical relationship when climatic factors were correlated to scorpionic accidents. On its turn, when it was verified the results of the geoprocessing analysis, it was seen that anthropic factors have been motivating the potentiation of the occurrence of these accidents.

“…Few commercial traps are not shaped with right angles, like a box. They do not employ angles less than 90 degrees, even though at least one Loxosceles species prefers refuges that offer acute angles (Stropa 2010). In our study, a total of four novel trap shape designs and one popular glue trap already on the market were tested to determine if one (or more) of the new designs were more likely to catch brown recluse spiders than the existing design.…”

While there are limited options for chemical-free Arachnid pest control, glue-traps are one suitable alternative to pesticides. The effectiveness of several three-dimensional glue-trap shapes for trapping the brown recluse spider, Loxosceles reclusa Gertsch and Mulaik (Araneae: Sicariidae), was investigated using four novel glue-trap shape designs, which were compared to an existing design currently on the market. These four novel and one standard shape designs were tested using pairwise comparisons. The most preferred trap design was a flat glue-trap with no covering. Although this type of trap was most efficient for capturing L. reclusa, it can pose risks in homes with children and pets for obvious reasons. Among the traps with coverings, the vertical strut trap was most preferred by the spiders, and should perhaps be the trap of choice for homeowners with children and pets.

“…Vetter and Rust (2008) showed that recluse spiders preferred vertical over horizontal retreats and previously occupied retreats with conspecific silk instead of new, clean retreats, but did not show preference for retreats in the range of cavity sizes that were tested. Stropa (2010) demonstrated that L. gaucho Gertsch spiders preferred cavities with angular instead of gently rounded walls.…”

The brown recluse spider, Loxosceles reclusa (Gertsch and Mulaik; Araneae: Sicariidae), was first determined to be medically important in North America in 1957. Since that time, its infamous reputation has spread far beyond its actual distribution, such that in areas in North America where the brown recluse is not known to exist, doctors diagnose a multitude of non-spider related skin lesions as recluse bites and home owners misidentify harmless spiders as recluses. In indigenous areas, this synanthropic spider can generate extensive populations within homes and work buildings where interaction with humans in the form of potential envenomations and anxiety-filled paranoia is heightened. Additionally, the brown recluse can be a valid real-world concern in the real estate housing business as well as spawning litigation. Reduction and control of brown recluses in homes and businesses is of importance for those who have proven populations of the spider. In this article, we review biology and life history of the brown recluse spider as it relates to pest management as well as control measures as they pertain to an IPM strategy for this urban arachnid.
