Field mice
Field mice are small mice that spend the winter under the snow, making tunnels to get around. We often find this problem in neighborhoods near vacant or wooded areas. To reduce their presence, cut the lawn shorter during the last mowing of the year in late October or early November (2″). Baits are also available at the garden center, but their effectiveness is not guaranteed. As soon as you notice the damage in spring, rake the lawn to remove dead grass from the tunnels and the surrounding lawn should grow back in these areas. If the damage is major, you’ll need to put in some soil and seed.
Skunks
Skunks can plough a field in search of grubs. Unfortunately, there’s nothing you can do about it. You’ll need to add soil and seed to repair the situation. A new layer of peat grass may also be the solution when the damage is more extensive.
