Let's get down to business in figuring out which pesky rodent is frustrating you. Entry points for moles are usually obscured by piles of dirt, while those of voles usually are not. Mole holes are roughly over 2" in diameter, while those of voles are 1" to 2". Moles like to leave dirt heaps, whereas voles just have a hole they enter through. Moles generally consume soil bugs, grubs and earthworms, while voles largely favor the roots of plants, such as your once beautiful lawn.
With it being so early on in the season, the brown spots usually are not going to be from a dull mower blade or toxic chemicals spilled onto your lawn. If you have a pet and the brown spots are consistent with potty breaks, then you are going to want to apply gypsum to revive the area. If you don't have a dog or the spots are not consistent with his potty breaks and are along your sidewalk or driveway, then you may have salt kill from the winter. The recommended remedy for this is going to be to replace the dead area with our highland sod. If you want to really work at it and think it may have a fighting chance, you can rake the brown spots up and then apply our Jirik Sod blend seed, black dirt and then apply a low nitrogen fertilizer.
Please be mindful of weather & potential field conditions that may cause a delay in any sod service.
Thank you for your understanding.
