We been using it for bait for 30 yrs.Was told it had shark oil.I'll have to try some of the other stuff tho you mentioned.Down here on the mexico/ca/az border,everything stings,jabs,pokes,or bites you.I hate fire ants.They even get into my pets food dishes.I have to either spray,(which keeps them gone for weeks)or put their food in a water pan.In fact.I'm going to ask if anyone has a tip on how to protect your property.Their just now coming out.I am going to try some of your tips on other things we have.Like the mirror.And the duct tape one,for sure.Thanks so much.I wished we had a board for just tips like this.As between all of us,we are an encyclopedia of info not available to the younger generation.Bookmarking this one.
