identifying a rodent pest outside in yard
Typical rodents for lawns in Kentucky include moles and voles. They tunnel under the soil surface, feeding on roots and worms. Contrary to previous research, their main source is not white grubs. Instead, moles and voles eat earthworms.
Control methods include traps but it is important to find an active tunnel. Moles and voles use a tunnel until the food source is used up and then creates a new one; they don't typically return to the old tunnel. Therefore it is important to identify an "active" tunnel to place a trap. Monitor the trap daily as it is often tripped.
Another option includes using Bromethalin; a pesticide infused into rubber worms. This product is well known under the brand name "Talprid" and can be found at most local farm supply stores. To use Bromethalin effectively, you still have to identify an active tunnel. Poke a small hole into the tunnel, and place a worm making sure to cover it back up with soil.
