Weed Control

Pre-Emergent Weed control is like insurance for your yard! You know the weeds will come, it is just a question of when and how bad will they be this season. Chandler and other cities of the Southeast Valley are known to be hit with winter weed annuals after the winter rains and summer weed annuals during Monsoon season. The goal is to prevent the seeds and spores of weeds that travel by wind and other animals from taking root in your yard. At Sun Lakes Pest Control we use an odorless, colorless herbicide that will not stain your house stucco, walkways, driveways, patios and landscaping rocks. Treating the rocks and crevices where weeds pop up while leaving no damage to the lawn or existing shrubs and trees. We recommend a Pre-Emergent Weed Control be applied every six months to control weeds in your yard.

Improve your chances for a weed free yard and a successful treatment by preparing your yard to be free of large existing weeds and leaf debris. We do not pull or clean up weeds as dead weeds are the responsibility of the customer to remove. Existing weeds which are visible are treated and could take 7-10 days to die. We cannot guarantee that weeds over 5 inches tall will die upon initial treatment.

Fear not!

Weed seedlings which are in the final phase of germination are very resistant to the chemical and will be retreated in the 4-6 week follow up treatment.

Sun Lakes Pest Control treats with high quality concentrated Gallery or Dimension herbicide, typical treatment area is 5,000 sq ft.
