Dwarf weaver typically poses a mild threat through venom injection via bites, primarily during its adult stage. The toxicity can affect both mammals, such as humans and dogs, as well as smaller creatures like other spiders and insects. Upon biting, the venom can cause discomfort and localized reactions, though it is generally not harmful to most animals due to its low intensity. Reactions may vary, with mammals often experiencing minor effects, while smaller animals may face more detrimental consequences.
