Yes, Victoria Falls is located in a tropical region where mosquitoes are present year-round, with peak activity occurring during the rainy season from November to April. Because the falls create a constant "spray" and localized rainforest environment, there is plenty of moisture for mosquitoes to breed. Most importantly, Victoria Falls (in both Zimbabwe and Zambia) is situated in a malaria-endemic zone. While the risk is present, it is manageable through a "multi-layered" approach to prevention. Travelers are strongly advised to consult a healthcare provider about taking malaria prophylaxis (preventative medication) and to use insect repellent containing at least 30% DEET. Most hotels and lodges in the area provide mosquito netting over beds and use "fogging" or coils to deter insects in common areas. It is best to wear long sleeves and long trousers in light colors during the "witching hours" of dusk and dawn when mosquitoes are most active. While you will almost certainly encounter mosquitoes, taking these standard precautions significantly reduces the risk of contracting mosquito-borne illnesses during your visit.
