The best advice is to make sure that the bait device is fresh and that when you touch it, you do so with clean hands. Be sure to wash hands before handling. It also helps to move the devices around if the ants are not feeding. You can also follow their trails to find the food source. Sometimes eliminating this food source (if possible) is the key to making baits work.
The other factor is the species of ants. Do you know what species of ants you are dealing with? We have a great page on how to kill ants here - http://www.epestsupply.com/ants.php
