Of course! The same way ants do it! Perhaps ants leave a small trail while exploring, and then upon finding food, follow their own trail home while leaving a stronger trail. This would cause lots of smaller weaker trails, and the occasional strong trail. Ants out looking for food would follow trails with chances of deviating from the trail based inversely on the strength of the trail. Meaning food sources would get more attention than the random dead-end trails.
