Figures compiled from entomology studies and pest control safety resources.
Crab spiders provide natural pest control, blending into plants and flowers to catch insects such as flies and moths. Their harmless nature makes them a low concern for households. Black widows, however, carry potent venom that can pose serious health risks if bites occur, requiring immediate medical attention in many cases. While they are generally non-aggressive, black widows tend to hide in undisturbed, dark spaces, making unexpected encounters possible. Crab spiders support garden ecosystems, while black widows represent a clear hazard when found indoors or around high-traffic outdoor areas. Effective spider control ensures that the benefits of harmless species remain while dangerous ones are addressed promptly.
