3 pack from Walmart for $6.24 on-line, but also available in store (on the aisle where the irons & laundry room stuff is) ​DO NOT USE THESE if you have pets or small children!

We have a small yard (in a Del Webb community) with a block wall in back (no small children or pets).  There were mice running back and forth by the fence & burrowing under the structural block posts.  I didn't want them getting close to the house, so I googled what to use on-line.

Actual mouse bait (for outside) is pricey (starting @ about $25+ and needs to be shipped).  MOTH BALLS do the trick for any living pests that you have (including the slithering "s word") ~ so I bought this box with 3 separate bags inside.  I opened 1 bag and emptied all the little balls along the fence (and into the holes) and haven't seen a mouse in days!  ** It would be perfect to put down gopher or armadillo holes too. 

SAFETY PRECAUTIONS:  They smell horrible (and can trigger migraines), so only open the packages outside (and put the others into a zip-lock baggie).  Use a scissors that you can wash really well with a bleach-based cleaner ~ and your hands may need to be washed multiple times!  ** I didn't realize all this and cut the bag open in my kitchen sink.  I needed to wash my sink multiple times ~ including putting my dish drying cloth into the washing machine ~ any silverware or cups that were anywhere near the sink needed to be washed multiple times ~ and I could still smell it in there for a couple of days!  I used a lysol-bleach spray and then also my apple cinnamon antibacterial foam kitchen soap ~ and spiced apple fragrance spray (it's October), but it took 2 days to go away!  I can certainly see why no animals like it!
