I have both Moles and voles in the yard! Any advice on the voles?

Castor Oil May Work Against BOTH Underground Pests

Castor oil definitely sends moles scurrying to do their tunneling in the neighbor�s lawn. And many gardeners report that it chases nasty voles as well! Most garden centers now carry ready-made castor oil repellant products in spray able and granular form. And here�s a special note to our listeners with more exotic pest problems: The labels on some of these products say they�re effective against armadillos and pocket gophers as well!

(If you can�t find any such products in your local garden center, Gardens Alive! sells dry, spreadable castor oil under the name �Mole-Med�)

Want to try mixing up your own at home? Just add two tablespoons of castor oil to a sprinkling can filled with a gallon of warm water, add two drops of dishwashing liquid, and sprinkle, stirring constantly, on the infested area.

Whether home-made or store bought, apply when the lawn and weather are dry. If heavy rains hit, repeat a day or two after they end; otherwise, reapply once a month until you see no new tunnels.

Holes? Oh no--VOLES!!!!

If you have lots of holes in your lawn, you have VOLES�fast-breeding plant-eating pests that are MUCH worse than grub and worm eating moles. Castor oil repellants�home made or store bought�may chase the pests over into your neighbor�s lawn. So might the garlic based sprays that keep mosquitoes out of outdoor areas.

Sorry, but a British gardening magazine tested those battery-powered vibrating devices you stick in the ground, and found that they did not repel underground creatures.

Having outdoor cats on patrol DOES work; save a mouser from a shelter, give them a warm place to sleep and access to the garden, and they�ll do endless good deeds for you. So will Jack Russell terriers and similar breeds of �ratting� dogs. As will hawks and owls if you put a roost in the middle of the infested area. Nothing fancy�just a cross beam six to ten feet off the ground for them to hunt from.

To protect tulip and crocus bulbs, fill the holes with sharp stones when you plant new Spring bulbs this Fall; a product called �Vole Block� is sold just for this purpose.

You can also catch voles in mousetraps baited with peanut butter; place the traps underneath big plant leaves; voles don�t like to come out in the open.

And you can protect a veggie garden from ANY burrowing creature with a fence sunk two feet into the ground. Because voles are SO small, however, you�ll need to make it a small gauge fence to begin with, or, even better�a six footer of regular animal fencing whose bottom three feet are reinforced with hardware cloth�no miserable mammal can get through those small openings!
