Leave it to professionals
It is important to understand that the methods available to non-specialists are different from those commonly used by professional mosquito control personnel. Pesticides are designed to kill the problem organism and they do so by being toxic. Therefore, some pesticides may pose risks to other organisms, including people, especially if not used correctly.
A combination of several factors determines exposure, including how much pesticide a person or animal takes in (the dose), the frequency of dosing and the duration of exposure. Exposure, in combination with innate toxicity (the amount of pesticide per unit of body weight required to cause harm), determines the level of risk to humans and other non-target organisms.
Trained and licensed pesticide applicators are educated to ensure target pests, like mosquitoes, are killed, while reducing the exposure of non-target groups. Trained personnel are also educated about using no more pesticide than what is required, as this reduces the amount of pesticide in the environment. Pesticide application is definitely one of those activities where more is not better.
Hence, effective mosquito control is complex, and technically demanding, and is best left to trained professionals for good lasting results.
