Initial pain at the bite site is generally trivial and may go unnoticed. It is commonly described as a pinch or pinprick; however, infants may present with unexplained crying. Within about 1 hour, systemic symptoms begin and may last for a few days.

Muscle cramping may occur locally, around the area bitten. It may extend into large muscle groups, such as the abdomen, back, chest, and thighs. Case reports suggest involvement of smooth muscles, such as bronchial or endometrial muscles.

Abnormal vital signs may include hypertension and tachycardia. Diaphoresis, locally, around the area bitten, or remotely from the site of envenomation, may occur.
