Reclaim your yard this spring and summer with treatments that kill active mosquitoes and disrupt breeding cycles.
East Tennessee's warm, humid summers create ideal conditions for mosquitoes from March through October, with peak activity June through August. Bradley and McMinn County's mix of wooded lots, detention ponds, and creek corridors provides abundant breeding habitat. OnGuard's yard spray program significantly reduces mosquito populations so your family can enjoy outdoor time without constant biting pressure.
| Month | Activity Level | Recommendation |
|---|---|---|
| March – April | Emerging — first generation hatches | First treatment of the season to suppress early populations |
| May – June | Building — pressure increases weekly | Monthly service; treat breeding areas aggressively |
| July – August | Peak — highest biting pressure | Maintain monthly service; don't miss treatments |
| September – October | Declining but still active | Continue service until consistent cool nights arrive |
Tennessee mosquitoes transmit West Nile virus and La Crosse encephalitis, both documented in the state. While most bites cause only irritation, vulnerable household members — young children, elderly adults, and those with compromised immune systems — face greater risk from mosquito-borne illness. Professional yard treatment adds a meaningful layer of protection beyond personal repellents.
Spring is the time to act. Treatment before populations peak is far more effective than chasing an established population mid-summer. Early-season customers see better results and lower long-term costs.

Our residual spray treatments last 21–30 days under typical East Tennessee summer conditions. Heat, heavy rain, and dense vegetation can reduce effectiveness faster, which is why we recommend monthly service from April through October. We reapply on a consistent schedule to maintain population suppression throughout the entire mosquito season without gaps.
Yes. Mosquitoes need as little as a bottle cap of standing water to breed. Common sources in Bradley and McMinn County yards include clogged gutters, low spots in lawns after rain, decorative planters without drainage, tarps or grill covers that collect water, and even dense leaf litter that stays wet. During our yard inspection we identify and treat all sources we find, and advise on ones you can eliminate yourself.
We apply our treatments to resting vegetation and shaded areas where mosquitoes harbor during the day — not to flowering plants where pollinators forage. Treatments are done early morning or evening when pollinators are less active, and we avoid direct application to blooming plants. The products we use have low residual toxicity to non-target insects when applied correctly.
Tennessee mosquitoes are known vectors for West Nile virus and La Crosse encephalitis, both documented cases in the state. While most people bitten experience only irritation, severe cases can occur — particularly in children under 16 (La Crosse) and adults over 60 (West Nile). Mosquito yard treatment significantly reduces biting pressure and consequently the risk of exposure to mosquito-borne illness.
Strongly yes. Early-season treatment in March and April targets the first generation before populations explode. It's far easier and more effective to suppress a small early population than to chase an established mid-summer one. Customers who start in spring consistently report better results than those who wait until July. OnGuard books spring slots early — call 423-951-5667 to get on the schedule.
