What specific type of complication should observation focus on following the initial cleaning and icing of a tarantula bite?

Signs of infection (increased redness, warmth, pus) or worsening systemic reaction

After administering basic first aid like cleaning the wound and applying cold, the crucial next step is careful observation to monitor for adverse developments. The primary concern shifts away from the venom's inherent properties and toward secondary complications. Observers must watch closely for signs indicative of a bacterial infection taking hold at the wound site, which include escalating redness, abnormal warmth spreading from the site, or the presence of pus. Additionally, although rare, monitoring for any sign of a systemic reaction—such as muscle cramping or breathing difficulty—remains necessary to determine if immediate medical intervention is warranted beyond simple home care.
