Diazanone (sp ck) n seven dust usta work but aint worth a crap anymore. Im using permethian n its keepin them at bay from the storage bin. Dogs dont giv the ants time to even get a whiff of their food.
X2 since seven dust went to a wimpy 5% it ain't worth using.
Not to get in your biz but Charles brought up a good point.....unless your feeding pups or attempting to recoope an under fed dog........shouldn't be any feed left in the bowl for ants to eat after feeding. If so.....might be over feeding em a bit.
