Put Poison down their holes.
Hi Colleen, here is a site with some remedies to get rid of them without a trap.
Poison is not good to use if you have pets,kids, animals in area that would also get poisoned. Sonic vibration you can get some on Amazon (solar)
Put the real hot red peppers in their tracts. They will run away from it. They were eating my friends flower roots and I told her to do that and they never bothered them again. Hope this helps you too.
