  • Call for help
  • Lay the victim down in a half-sitting position and avoid any effort
  • Immobilize the affected limb
  • Clean the wound
  • 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.
