Prevent Weeds, Protect Your Space
Arizona Weed Control - Same-Day Service
Weeds in Arizona don't follow the same rules as the rest of the country. Most states deal with one growing season. Arizona has two - which means your property is under pressure almost year-round. Lunar Pest Control has been treating Arizona properties for over 13 years across 26 cities. We know exactly when to apply what - and timing is everything.

Why Arizona's Weed Problem Is Different
Two Growing Seasons, Not One
Winter weeds germinate in fall and take over from November through March. Summer weeds follow right behind, sprouting in spring and thriving through the monsoon. Treat once a year and you're leaving an entire season unprotected.
Desert Soil Works Against You
Arizona's sandy, alkaline soil doesn't hold herbicide barriers the way dense clay soil does in other climates. Products break down faster here, which means timing and product selection matter more than anywhere else.
Irrigation Creates Ideal Conditions
The same water keeping your landscape alive is also feeding weeds. Drip lines, flood irrigation, and overwatered turf all create micro-environments where weeds thrive - sometimes faster than the plants you actually want.
HOA Pressure Is Real
Most Arizona HOAs enforce landscaping standards hard. Visible weeds can trigger violation notices within days. Staying ahead of growth isn't just cosmetic - it protects you from fines.
Common Arizona Weeds We Treat
Spurge
Low-growing weed with milky sap that spreads flat across gravel and concrete. Tough to pull because it breaks at the stem and regrows from the root.
Puncturevine (Goatheads)
Produces spiny seed pods that puncture tires, shoes, and pet paws. Spreads aggressively in gravel yards and along sidewalks.
Bermuda Grass (Invasive)
Sends runners into flower beds, rock landscaping, and hardscape cracks. Nearly impossible to remove by hand once established.
London Rocket & Wild Mustard
Winter weeds that can grow several feet tall in weeks. They take over gravel yards fast and create an eyesore that invites HOA notices.
Buffelgrass
An invasive species that creates serious fire hazards in the desert. It burns hot, spreads fast, and chokes out native plants.
Nutsedge
Looks like grass but isn't. Produces underground tubers that make hand-pulling useless - you pull one, and three more grow back from the tubers left behind.
The Lunar Lock Protocol
Our four-step process for getting weeds under control and keeping them there.
Property Assessment
We walk your property and evaluate existing weed growth, trouble spots, soil conditions, and landscaping type. Every property is different - a gravel front yard needs a different approach than a turf backyard with flower beds.
Pre-Emergent Barrier Application
The most important step - and timing is everything. Pre-emergent herbicide creates an invisible barrier in the soil that prevents weed seeds from germinating. Applied correctly, it stops roughly 90% of seasonal weeds before they ever break the surface.
Application windows:
Late September – October for winter weed prevention
Late February – March for summer weed prevention
Post-Emergent Targeting
No pre-emergent catches everything. For the weeds that break through, we spot-treat with selective post-emergent herbicides that kill the weed without harming your lawn or landscape plants.
Seasonal Follow-Up
We check back before each weed season to reapply barriers and address any new growth. Consistent treatment builds on itself - year two is always better than year one, and by year three most properties need minimal intervention.
About the Blue Dye
You'll notice our pre-emergent applications leave a temporary blue tint on treated surfaces. The dye serves a real purpose - it lets our technicians see exactly where product has been applied, ensuring full coverage with no gaps. The color fades within a few days depending on weather and surface type. It's completely safe for your lawn, plants, and hardscape, and any marks on pavement wash away with water or rain.
Residential & Commercial Weed Services
Residential
Single-family homes, townhomes, and HOA communities. We treat gravel yards, turf lawns, garden beds, driveways, patios, pool decks, and side yards. Most residential treatments are completed same-day.
Commercial & Property Management
Apartment complexes, office parks, retail centers, HOA common areas, golf courses, sports fields, parks, and cemeteries. We work with property managers on scheduled treatment programs that keep large properties clean year-round without constant oversight.
Frequently Asked Questions
How long does it take for weed treatment to work?
Post-emergent treatments show visible results within a few days to a week - weeds yellow, wilt, and die back. Pre-emergent is preventive, so you won't see dramatic results right away. What you will notice is that weeds simply don't show up when the next season hits.
Is the treatment safe for pets and kids?
Yes. Our products are safe for both pets and children once dry, which typically takes 30 minutes to an hour. We'll let you know exactly when it's safe to return to treated areas.
Is professional weed control actually better than doing it myself?
By a lot. Professional-grade pre-emergents last longer and work better than retail products. More importantly, we know the exact application windows for Arizona's two weed seasons. Treating two weeks late can be the difference between a clean yard and a weed-covered one.
What areas of my property can you treat?
Lawns, gravel beds, driveways, patios, pool decks, garden beds, sidewalks, parking areas, side yards - essentially any area where weeds are growing or could grow.
How often should I have my property treated?
We recommend treatment twice per year - once before each weed season (fall and late winter). Some properties with heavy weed pressure benefit from quarterly visits during the first year to get established growth under control.
Will the treatment harm my lawn or plants?
No. We use selective herbicides that target weeds and invasive grasses without affecting the plants you want to keep. If you have a vegetable garden, let us know - we'll adjust the application to keep edible plants safe.
Why do you use blue dye in the pre-emergent?
The dye gives our technicians a visual guide to ensure complete, even coverage across your property. No missed spots. It fades within a few days and is completely safe.
Do you offer a guarantee?
Yes. If you're not satisfied with the results, we'll come back and make it right. Weed control depends on proper timing, and we stand behind our application schedule.
