I used the Advion gel inside 2 weeks ago - my brother told me to try it out. It got rid of about 80% of the ants. I then ordered the indoor/outdoor kid as I was impressed by the Advion gel he gave me. I put down the granular bait around the outside - not in the provided bait stations - just a little here, a little there. I have had issues in the past with squirrels tearing up bait stations.
Then I sprayed a gallon of the Advion concentrate around the outside. Within 2 days I see no more inside ants, not even stragglers. I put a little Max gel in my pantry, not much. Great stuff!
