What factors may have caused the pillbug to be attracted or repelled by a substance?

Pillbugs may be attracted or repelled by substances based on factors such as moisture levels, odor, and chemical composition. They typically prefer damp environments, so substances that retain moisture might attract them, while dry or harsh-smelling substances could repel them. Additionally, the presence of food sources or toxic compounds in a substance can influence their behavior, guiding them toward favorable habitats or away from harmful ones.
