Custom Weed Control Solutions for a Healthier, Cleaner Yard
Tailored Pre- and Post-Emergent Treatments Backed by a 6-Month Warranty
Our knowledgeable and experienced staff will assess the property you need treated to determine the best approach. There are many factors to consider such as the type of weeds present, what plants are established in the yard, future plans associated with the space, and overall customer expectation. A plan is tailored to your specific property and the final estimate is generated.
The property you need treated will be tended to by one of our extensively trained technicians. We apply the pre-emergent (which prevents seeds from taking root) and post-emergent (which kills current weeds) at the same service; this is the most common treatment. Moving forward with your custom lawn weed control plan, we will determine what (if any) weeds become resistant to post-emergent products. which we will address after the initial appointment.
Expert Care, Follow-Ups, and Guaranteed Results from Cummings Termite and Pest
Should your yard be overgrown with weeds, we may need an additional visit to knock down the activity. This will be made clear upon our first onsite assessment. Our thirty day follow-up is included in the first service and we guarantee that you will be satisfied with the results. We provide a 6-month service warranty on all full yard pre-emergent treatments and if after that 6 months you are completely unsatisfied, we will make it right or we will provide you with a refund for the service.
After our initial pre-emergent application, we will conduct a thirty day follow-up to assess the success of the service. At this visit, we will be able to determine if there is any resistant weed or if there are any areas that are designated special circumstances and must be approached with a more tailored application.

Frequently Asked Questions
What types of weeds are most common in the East Valley? +
The most troublesome weeds in Scottsdale, Mesa, Gilbert, Chandler, Fountain Hills, Paradise Valley, and Rio Verde include puncture vine (goathead), spurge, Russian thistle (tumbleweed), bermuda grass in landscape beds, London rocket, globe chamomile, and various species of amaranth and mustard. These weeds are adapted to Arizona’s heat and alkaline soils and can be incredibly persistent without proper treatment.
Why do weeds keep coming back even after I pull them? +
Pulling weeds removes the visible plant but often leaves the root system intact, which simply regrows. Many Arizona weeds also have extensive seed banks in the soil — a single puncture vine plant can produce thousands of seeds that remain viable for years. Without a pre-emergent herbicide to prevent germination, you are fighting an endless battle. Cummings Pest Control uses a combination of pre-emergent and post-emergent treatments to break the weed cycle.
When is the best time to apply weed control in Arizona? +
Timing is everything for effective weed control in the desert. Pre-emergent herbicides should be applied before weed seeds germinate — typically in early fall (September to October) for winter weeds and in late winter to early spring (February to March) for summer weeds. Post-emergent treatments can be applied whenever active weeds are present. Cummings Pest Control schedules treatments at optimal times throughout the year to keep your property weed-free.
What is a pre-emergent and how does it work? +
A pre-emergent herbicide creates a chemical barrier in the top layer of soil that prevents weed seeds from germinating successfully. It does not kill existing weeds — it stops new ones from sprouting. This is the most effective long-term weed control strategy for Arizona properties. For best results, pre-emergent should be applied before the weed season begins and watered in lightly. Cummings Pest Control uses professional-grade pre-emergent products that provide longer-lasting protection than retail options.
Will weed treatment kill my existing plants and trees? +
When applied correctly by trained professionals, weed treatments target weeds without harming your desirable plants, trees, or grass. Cummings Pest Control technicians are experienced in applying selective herbicides that target broadleaf weeds while leaving ornamental plants and turf unaffected. We take care around sensitive plantings and adjust our approach based on your specific landscaping. We always communicate with you about what to expect before treatment.
How often do I need weed control treatments in Arizona? +
For most East Valley properties, we recommend a minimum of four treatments per year — pre-emergent applications in fall and late winter, plus post-emergent spot treatments as needed during the growing seasons. Properties with heavy weed pressure, gravel lots, or commercial sites may benefit from more frequent treatments. Cummings Pest Control offers annual weed control plans that keep your property consistently clean and weed-free.
Can I just use rock or gravel to prevent weeds? +
Rock and gravel alone do not prevent weeds. Wind and water carry soil and organic matter into gravel over time, creating a growing medium for weed seeds. Without a weed barrier fabric underneath and regular treatment, gravel landscapes actually become some of the worst weed problems we see. If you already have a gravel landscape that is overrun with weeds, Cummings Pest Control can treat the area and help you develop a maintenance plan to keep it clean.
Do you treat commercial properties and HOA common areas for weeds? +
Yes. Cummings Pest Control provides commercial weed control services for businesses, HOA common areas, vacant lots, and commercial properties throughout the East Valley. We understand that property appearance matters for businesses and communities. Our commercial weed programs include scheduled treatments, detailed reporting, and the reliability that property managers need. We currently serve commercial clients across Scottsdale, Mesa, Gilbert, Chandler, and surrounding areas.
Are weed control products safe for children and pets? +
The herbicides we use are EPA-registered and applied by licensed technicians according to label directions. We recommend keeping children and pets off treated areas until the product has dried, which usually takes a few hours. Once dry, treated areas are safe for normal use. Cummings Pest Control always prioritizes the safety of your family, pets, and the environment in our treatment approach.
Why should I hire a professional instead of buying weed killer at the store? +
Professional weed control from Cummings Pest Control offers several advantages. We use commercial-grade products that are more effective and longer-lasting than retail options. Our technicians know which products work best on specific weed species in Arizona’s unique conditions. We apply at the right rates and at the right times for maximum effectiveness. And our regular treatment schedule means you never have to think about weeds again. Most customers find that professional treatment is more cost-effective than repeatedly buying retail products that underperform.
