The lawns I have the worst mole problem with this year are ones that I put mach II grub control on. Maybe they are on the move looking for somthing else to eat?
Someone told me today that they heard that castotoil sprayed on the lawn will make the moles sick and they will leave. Has anyone heard if this actually works? and if so where can I get a lot of castoroil?
I haven't heard of that one yet, but you never know. Castor oil is used to clean out the bowels and digestive tract. You can find it in Walgreens, Walmart, Meijer, etc... . That would be one expensive lawn treatment; especially on a large property. Don't know if you could dilute it with veg. oil.
The reason for the abundance of moles is due to the wet soil and earthworms moving closer to the surface. Most garden centers will have a Castor Oil/Pepper spray which is supposed to deter these varmits, but not sure how effective it is. I would be careful with children and pets though.
