Moles and crickets can both cause much trouble to your garden. Moles make an underground tunnel system and use it to colonize and multiply. From below, they eat and destroy roots and bulbs. Crickets can also run rampant because they lay their eggs and before you know it, you have hundreds of crickets invading the garden. They are very difficult to manage and get rid of.
Identify mole tunnels by looking for piles of soil. Insert a long stick into the mounds to see if the ground has an open space below. This indicates that the moles dig in that location.
Lay a trap in the tunnel that impales or chokes the animal. Put it in the middle of the passageway so that the mole has to step into it.
Use poison to kill the moles if your state does not permit the use of traps. Get poisoned bait that contains bromethalin. The bait looks like earthworms, which is what moles typically eat. Put the bait in the tunnel so the moles eat it. It will kill them within 24 hours.
Mix 1 ounce of castor oil with 1 cup of Murphy's Oil Soap and 1/4 cup of cayenne pepper. Combine the three ingredients with water in a 2-to-1 mixture. Fill a spray bottle with the poisonous solution and spray it in the areas the moles go. You can also pour it right into the tunnel.
Pick up crickets by hand and kill them if there are not too many. Simply squash them between your fingers.
Protect your gardens with a screened box or cones. Crickets will eat through plastic row covers or cloth, however, so make sure the material is one that they cannot consume.
Keep a border of tall grass or plants around your garden. This will trap the crickets and keep them from migrating to your plants. If you mow the grass or allow it to become dried out, however, the pests will descend onto the garden.
Treat the pests with an insecticide at the start of the season. It's easiest to kill them when they are young nymphs as opposed to waiting until they grow into adults. Follow the product instructions.
Apply a bait that contains carbaryl to the perimeter of your garden before crickets invade. These chemicals work for a few days and will become ineffective when it rains or you water the garden. Reapply, according to the label instructions, if the migrations continue to be an issue.
