Mosquito control costs $350 to $1,000 per season on average. The cost for each treatment visit ranges from $80 to $150 for a 1/4- to 1/2-acre yard, depending on the treatment methods used. Many mosquito control services use a combination of treatment methods to attack the mosquitos at all stages of their life cycle. 

Mosquito control service typically includes an initial inspection of the property to identify the specific areas mosquitos are breeding. A trained technician may use one or several treatment methods, such as aerial spraying or dusting to kill mosquitos, eggs, and larvae, and using larvicides in any standing water that cannot be removed. Follow-up treatments occur every 21 to 30 days during peak mosquito season. 

Mosquito treatments last 3 to 4 weeks on average. The length of effectiveness depends on the level of infestation, your local climate, and the type of treatment applied. Synthetic treatments typically lasts longer than others.

Rain does not affect mosquito treatments, provided the treatment has time to dry. Treatment drying time ranges from 20 minutes to 1+ hours.

Mosquito season runs from April to October in most regions. Southern states experience a longer mosquito season that typically starts in March and ends as late as November. The best time to start mosquito control service is in the early spring just before the mosquito season starts.

Yes, most mosquito control products applied by a trained professional are safe for humans and pets. These pesticides are typically applied to targeted areas, in low concentrations, and dry very quickly. Still, people with extreme chemical sensitivities should err on the side of caution and stay out of the area during treatment.
