Vole Control

Vole Control

Rodent baits are often used to control voles. Their populations tend to be cyclical and once established, vole colonies are not easy to control.
One of the most effective ways to discourage voles from moving in is to simply mow grasses down to no more than two inches or disk around sites that need to be protected. Either action will reduce or eliminate their preferred habitat. Often, if you don’t control the vole population, there may be little you can do about it. The secret is to protect sensitive sites – such as gardens – by mowing or disking the area before the population gets too high.
If you must use a rodent bait to control voles, only use those baits intended for field rodents. Their labels will identify chlorphacinone or diphacinone as the active ingredient. Baits should only be used in small treatment areas and the areas should be checked daily for dead rodents.
With very high vole populations, rodent baits may ultimately have little effect. The best approach is to protect sensitive sites – such as gardens – by mowing or disking the area before the population gets too high.
