I placed the block inside of the vole holes in the ground as the snow melted. I also broke up some of the blocks and put it in the "vole lanes" in the graass. There was some early activity. Now I have seen no further vole damage or voles. for a couple of weeds. Great product
We had very destructive Vole damage to our Blue Rug Junipers. We tried moth balls and underground sonic approaches - Non-effective at all! Purchased 5 bait stations and 'KAPUT'. Located stations 11 feet apart and placed them under the arms of the Junipers (66'x5'). We checked them every week for activity (started slowly) and continued to replace and clean the stations. After 12 weeks, the voles ate themselves into eternity. Now our task is to nurture the Junipers back to health. Would recommend this product to anyone needing vole control.
