we have done a few different times and what we found gets best results for our area was the beginning of February, end of February, and Beginning of March. If we target businesses we usually push for fall advertising or middle January. Thats all assuming you start generally the same time as us which is the first week in april and march for chemicals.
We live by the whole repetition is key saying with advertising. Especially homes within 5 miles of our location we try to saturate the market here to give us a tight run.
