- Immobilize the affected limb

- The venom of this species being thermolabile, it can be neutralized if it is submitted to a temperature of about 45 °C. It is therefore possible to heat the wound. This popular technique should be practiced with great care so as not to aggravate the wound by burning it. It is advisable to immerse the affected limb in hot water.
- If the puncture is too deep, heating the wound will be less effective.
Sometimes the sting can cause discomfort or even loss of consciousness in the victim. The stings are usually very painful.
