Don't get glue boards and other insect type "traps" confused with baits. The baits don't "trap" the ants, only provide a food source that kills them.
As far as carpenter ants go, they feed on aphids, scale, mealybugs, plant juices and other "natural" food sources which are always found outdoors. Baiting indoors is sometimes effective with Maxforce Carpenter Ant Bait Gel or with Advance Carpenter Ant Bait.
However, using these products is hit and miss, because they are food grade and only last a few short days. They have to continually be reapplied, every 3-4 days. The KM Ant Pro System by comparision, will provide a steady flow of bait for up to 4 months before the bait has to be changed.
Hope this helps.
