Moles are a common garden pest. Moles typically only eat insects and worms; however, their tunnels can cause problems for your lawn or garden. They dig under lawns and seed beds causing disruption and allowing plant-eating rodents access to the roots or bulbs of your plants. If you are having trouble with moles, consider trying to trap the moles and transporting them to a distant location, such as a faraway field. Trap the moles by using mole bait.
Natural Mole Bait
Trapping is the most effective and reliable method for controlling moles. Two forms of traps are available: live traps and lethal traps. Live traps do not kill the mole and allow you to transport the mole off your property; lethal traps kill the mole. Both methods, in order to be effective, require some form of mole bait. If you prefer live trapping, consider using natural mole bait.
Just as you use worms and other forms of fish food to catch fish, use the mole's natural diet to lure the mole into a trap. Moles eat a diet of insects, earthworms, beetles, and grubs. Many of these food sources are available right in your back yard. To prepare the live bait, collect specimens of insects and worms. Place these food sources into a small container which can then be placed into your live mole trap. Keep in mind that live sources of food are more likely to attract moles, but also more likely to escape your trap; plan accordingly. After you have collected the mole's natural diet as bait, simply wait for the mole to run into the trap. One of the key aspects of mole control is patience and persistence. Check your traps daily and replace the mole bait as needed.
Chemical Mole Bait
According to doyourownpestcontrol.com, the first effective mole-killing bait was developed by Bell Laboratories and is called Talpirid. Talpirid is a poisonous substance that mimics the mole's natural food. It comes in "worm" form and is made to look like the mole's natural food source: earthworms. The active ingredient in the substance is a poison called bromethalin. Each Talpirin worm contains a deadly dose of bromethalin; therefore, do not use this substance if you intend to keep the moles alive and transport them off site. If you intend to use Talpirin, use it only in lawns, parks, and around homes; place the Talpirin underground in the mole runways or in subsurface feeding tunnels.
