Mosquito Treatment & Management in Maine
Yard Guard is our complete outdoor tier — it reduces both mosquito and tick pressure in the spaces your family actually uses. Decks, patios, play areas, yard perimeter. Natural options available. Built around how mosquitoes actually move through Maine properties.

Mosquito pressure has been climbing in Maine
Maine summers used to give us a few weeks of mosquito pressure followed by relief. Not anymore. Warmer winters, wetter springs, and longer humid stretches have given mosquito populations a longer active season here. We have customers who can't sit on their own deck after 4 PM from June through September without getting eaten alive.
There are over 40 mosquito species documented in Maine, but you don't need to know any of their names to manage them. They share the same lifecycle (egg, larva, pupa, adult), they all need standing water to reproduce, and they all rest during the day in shaded vegetation, under decks, in shrub beds, and along the foundation of buildings before they come out to bite.
Mosquito-borne disease in Maine is real but manageable. West Nile virus, Eastern Equine Encephalitis (EEE), and other arboviruses do circulate here in mosquito and bird populations. The CDC tracks Maine cases every year. Personal protection is a piece of it; reducing the mosquito population on your property is another piece.
Our Yard Guard program treats the resting zones where adult mosquitoes spend their daylight hours. We do not blanket the whole yard. We treat the spots where mosquitoes actually live during the day so they cannot come out and find you in the evening. Standard and plant-derived organic options. Both run on a four-visit seasonal schedule with optional add-ons for high-pressure properties.
Yard Guard: targeted to where mosquitoes rest, not blanket-sprayed
Mosquitoes spend their daylight hours hiding in shaded vegetation. We treat those resting zones so the population drops before they come out to bite at dusk.
Four-visit seasonal program
Four perimeter and resting-zone treatments through the active mosquito season, timed to Maine breeding windows. Late-spring start with three follow-up treatments to catch the early summer build, the midsummer peak, and the late-season second emergence.
Resting-zone targeting
Adult mosquitoes spend the day resting in shaded vegetation, shrub beds, dense ground cover, and under decks. We treat those zones, not the open lawn, because that is where the population lives between meals.
Yard Guard Organic option
Plant-based active ingredients (essential oil derivatives) for families that want a softer profile around kids, pets, and pollinators. Same four-visit schedule, same resting-zone targeting.
Stagnant ponds and persistent sources
For properties with stagnant ponds, drainage ditches, retention areas, or other persistent breeding sources you cannot empty, we can treat with specialized mosquito dunks that manage the larvae before they become biting adults. Wasp nest removal and tick testing also available as add-ons.
Standing water sources you need to eliminate yourself
We do not treat birdbaths, kiddie pools, or simple containers. Eliminating the water itself stops the breeding cycle, and that is the homeowner's job. Walk your property after the next rain and address every one of these.

Mosquito management FAQs
The questions we hear most from families thinking about Yard Guard.
Is Yard Guard the same as mosquito control?
Yes. "Mosquito control" is the phrase most people search for; Yard Guard is our name for it. We call it mosquito management because we target the shaded resting zones where mosquitoes actually spend the day rather than blanket-spraying the whole yard. Same goal: far fewer mosquitoes on your deck and patio in the evening.
Does Yard Guard cover ticks too, or just mosquitoes?
Both. Yard Guard is the complete tier of our pest program — it covers ticks and mosquitoes together, so you choose it instead of running two separate programs. If your only concern is ticks, our standalone Tick Management program is the more focused option. If you want both pests handled, Yard Guard is the one program that does it.
When should mosquito treatments start in Maine?
Late May through early June for most of central and Downeast Maine. The first generation of adult mosquitoes emerges as soon as we get a few warm humid stretches after the snow leaves. Starting too late means you are already fighting an established population.
The four-visit Yard Guard program runs through the active season: late-spring start, an early-summer follow-up, a midsummer treatment, and a late-summer treatment to catch the second emergence peak.
Are mosquito treatments safe for kids and pets?
Our standard Yard Guard product is selected for a favorable profile around people and pets when used as intended. We treat the resting zones (shaded vegetation, shrub beds, under decks, yard perimeter), not the open lawn where the family actually plays.
For families that want a softer profile, our Yard Guard Organic program uses plant-derived essential oil active ingredients. Same four-visit schedule, same treatment zones, naturally derived chemistry. Many families with young kids or sensitive pets choose the organic option.
What is the difference between Yard Guard standard and Yard Guard Organic?
The standard Yard Guard product has a longer residual on treated vegetation, which means each treatment lasts longer between visits. The Organic option uses plant-derived active ingredients with a shorter residual but a softer profile around kids, pets, and pollinators.
For most properties, both options provide similar seasonal mosquito relief on the four-visit schedule. We will tell you which we think makes more sense for your specific property when we walk it.
Where on my property do you treat?
The resting zones where adult mosquitoes spend their daylight hours: shaded shrub beds, dense ground cover, under decks and porches, the back side of outbuildings, and any cool, dark, moist zones along the property perimeter.
We do not treat the open middle of the lawn because mosquitoes do not rest there. Blanket-spraying the whole yard wastes product and exposes more of the property than needed without doing anything for actual mosquito pressure.
How long does one mosquito treatment last?
Roughly 3 to 4 weeks per treatment, depending on rainfall, irrigation, and how much new vegetation grows in. The Yard Guard Organic option is on the shorter end of that range. The four-visit program is built so the treatment windows overlap and you have continuous coverage through the active season.
Will Yard Guard hurt bees and pollinators?
We do not treat blooming flowers or pollinator-active zones. Our crews avoid treating during peak pollinator activity windows when possible, and we prioritize treatment in the resting zones (shaded shrub beds, under-deck areas) where pollinators do not typically forage.
The Yard Guard Organic option is the better fit for properties with active beekeeping, pollinator gardens, or homeowners who want the softest possible profile around bees.
Can I just use citronella candles or DEET instead?
Personal protection (DEET, picaridin, permethrin-treated clothing) and citronella products work for individual protection during specific evening hours, and we recommend them. They do not reduce the mosquito population on your property, though.
Yard Guard reduces the actual number of mosquitoes that make it to your deck, patio, and yard zones in the first place. The two approaches work well together: a treated property plus personal protection during evening outdoor time.
Do you treat stagnant ponds and other water features for mosquitoes?
Yes. For stagnant ponds, drainage ditches, retention areas, and other persistent water sources you cannot simply empty, we treat with specialized mosquito dunks. The dunks float on the water and slowly release a larvicide that manages mosquito larvae before they become biting adults.
The active ingredient is selected for a favorable profile around fish, pets, wildlife, and pollinators. It targets mosquito and related larvae specifically. We add this treatment to Yard Guard properties where the breeding source cannot be eliminated by emptying.
How can I reduce mosquitoes between treatments?
Eliminate standing water. This is the single most effective thing a homeowner can do. Empty buckets, plant saucers, kiddie pools, and tarps after rain. Refresh birdbath water every few days. Clean clogged gutters. Cover or fill any container that holds water for more than a few days.
Beyond standing water: trim back overgrown shrubs and ground cover near outdoor living areas, mow tall grass at the property edge, and add a fan to your deck or patio for evening hours. Mosquitoes are weak fliers and a fan is surprisingly effective at keeping them away from a specific seating area.
Should I worry about mosquito-borne diseases in Maine?
Maine has documented cases of West Nile virus and Eastern Equine Encephalitis (EEE) every year, and other arboviruses are tracked by the CDC and the Maine CDC. Cases are not common, but the risk is real, especially in late summer when virus circulation in mosquito and bird populations is at its highest.
Reducing the mosquito population on your property is one piece of prevention. Personal protection during evening outdoor hours is another. Avoiding standing water on your property addresses the breeding source.
What customers tell us in our service surveys
Verified feedback from our post-visit customer surveys.
Green Thumb always leaves info that the yard was treated and the type of treatment. They always keep the deer fence locked!! When calling or emailing they are very responsive. We have noticed such an improvement in regards to pest control - very few mosquitoes and ticks.
Green Thumb showed up as scheduled and did a wonderful job. Everything went well and my family is able to enjoy the outdoors with no worries of ticks or other bugs in our back and front yard. Thank you.
The application was applied evenly and covered the entire area!

Yard Guard is the complete tier of our Pest Management program
Our pest programs are tiered. Yard Guard is the complete outdoor tier — it covers both mosquitoes and ticks, so it steps up from our standalone Tick Management program rather than running alongside it. Many customers add Home Defense for the structural pests that try to get indoors. Our Pest Management program is where it all comes together.
