The answer to 'how long does mosquito control treatment last' is that the effectiveness of mosquito control treatments can vary, but typically lasts for 2-4 weeks on average. The duration depends on several factors, including the type of treatment, weather conditions, and the local mosquito population.
For example, barrier sprays applied to landscaping and foliage around the home can provide protection for 2-3 weeks before needing reapplication. Larvicide treatments that target mosquito breeding sites may last 4-6 weeks, as they continue to kill off emerging mosquito larvae. Fogging or misting treatments that kill adult mosquitoes on contact usually provide immediate relief but only last for a few days to a week.
