What Sets Blue Tree's Mosquito and Tick Control Apart

Most mosquito services broadcast the same spray across every open lawn on the route. Blue Tree's program is run by Mark Peasley, a Penn State graduate with two decades of turf science experience, and it starts with a walk of your property, not a route sheet. Treatments target the places mosquitoes and ticks breed and harbor: the foundation, ornamental beds, mulch, downspouts, and high-moisture zones. You choose an organic program or a synthetic one, and licensed applicators follow label directions and Pennsylvania requirements on every visit. If results fall short after an application, Blue Tree returns and re-treats at no additional cost. That standard has kept this company in business since 1983.

Our Mosquito and Tick Control Process

From the first property evaluation through end-of-season review, the Healthy Yards team follows a clear sequence. You will know what each visit covers and when to expect the next one.
1

Step 1: Free Property Evaluation

Mark Peasley or a member of his turf care team walks your property and looks for the conditions that drive mosquito and tick pressure: shaded ornamental beds, mulch, downspouts, standing water, and the wooded or tall-grass edges where ticks wait for a host. You talk through how your family uses the yard, from the swing set to the patio, so the treatment plan matches real life.
2

Step 2: Program Recommendation

Based on the evaluation, Mark recommends an organic program or a synthetic one. The organic option uses a natural blend of oils to deter insects. The synthetic option uses EPA-registered insecticides approved for residential use. He explains how each works, what the season looks like, and how household sensitivities, gardens, or pets factor into the choice. Pricing reflects your property's size and conditions.

Step 3: First Barrier Treatment

A licensed applicator applies the first barrier treatment to the target zones identified during your evaluation: the foundation, ornamental plantings, mulch beds, downspouts, and high-moisture areas. Blue Tree does not blanket-spray the open lawn. Application follows the product label and Pennsylvania state requirements, and the team documents baseline conditions so you can judge the difference the program makes.

Step 4: Recurring Treatments Through October

Treatments continue on a recurring schedule across the season, which runs from March through October in Southeastern Pennsylvania. You receive notice before each visit, and the crew works the harborage zones as the season shifts from spring tick activity to peak summer mosquito pressure. If a stretch of wet weather raises pressure between visits, tell the team what you are seeing and the next application adjusts.

Step 5: Season Review and Re-Treatment Guarantee

Every program carries Blue Tree's re-treatment guarantee. If results fall short after an application, the team returns and re-treats at no additional cost. At the end of the season, Mark reviews how the property responded and adjusts the next year's program, the same way he manages fertilization and weed control for lawns across the six-county service area.

Designed for Southeastern
Pennsylvania's Mosquito and Tick Season

Humid summers, wooded lot lines, creek beds, and heavy deer traffic make Southeastern Pennsylvania prime habitat for mosquitoes and the blacklegged ticks that carry Lyme disease, a risk the CDC documents across Pennsylvania every year. The season here runs long, from the first warm stretch in March until the leaves drop in October. Blue Tree's program is built around that local calendar, with treatments that follow tick activity in spring and fall and mosquito pressure through the summer peak. Homeowners across Montgomery, Bucks, Chester, Delaware, Lehigh, Berks, and Philadelphia Counties use the program to keep patios, pools, play sets, and garden beds usable through the months they want to be outside.

Complete Your Healthy Yards Program with Lawn Care and Year-Round Maintenance

Lawn Fertilization Programs: Multi-step feeding programs calibrated for Southeastern Pennsylvania's growing season, managed by the same turf care team that runs your mosquito and tick treatments.

Aeration and Overseeding: Core aeration relieves compacted clay soil and overseeding thickens thinning turf, with fall timing matched to local conditions.

Weed Control: Pre-emergent and post-emergent treatments that target the weed species active in this region.

Year-Round Property Care: Premier Outdoor Services handles seasonal cleanups, bed maintenance, and pruning, so the whole property gets the same attention as the lawn.

Common Questions

The treatment season runs from March through October. Ticks become active during the first warm stretches of early spring, and mosquito pressure builds through the summer before tapering in fall. Blue Tree applies barrier treatments on a recurring schedule across that window, and Mark Peasley's team confirms the right start date and schedule for your property during the free evaluation.

Blue Tree offers two program types. The organic option uses a natural blend of oils to deter insects. The synthetic option uses EPA-registered insecticides approved for residential use. Licensed applicators follow product label directions and Pennsylvania state requirements on every application. Discuss program selection with our turf care team based on your property's characteristics and any household sensitivities, including pets and young children.

Treatments target the zones where mosquitoes and ticks breed and harbor: the foundation of the house, ornamental plantings, mulch beds, downspouts, high-moisture areas, standing water zones, and the property perimeter. Blue Tree does not broadcast-spray the open lawn. Targeting the harborage areas puts the treatment where it works instead of where it looks busy.

The organic program uses a natural oil-based blend that deters mosquitoes and ticks, a fit for households that prefer a chemical-free approach. The synthetic program uses EPA-registered insecticides approved for residential use. Both follow the same targeted application method and the same season, and both carry Blue Tree's re-treatment guarantee. Mark's team walks through the trade-offs during your evaluation so the choice fits your household.

Blue Tree stands behind every application with a re-treatment guarantee. If results are unsatisfactory after a visit, the team returns and re-treats at no additional cost. Heavy rain and standing water on neighboring properties can affect how long a barrier holds, so tell the team what you are seeing and they will make it right.

Barrier treatments reduce tick habitat and target the perimeter zones where blacklegged ticks, the species that carries Lyme disease in Pennsylvania, wait for a host. The CDC documents Lyme disease cases across the state every year, so prevention matters here more than in most regions. No outdoor treatment removes every tick, which is why the program pairs targeted applications with practical guidance on the conditions that draw ticks into a yard.
