Colorado potato beetles are rarely seen as problems in home gardens despite the fact that a few may be very conspicuous. Overwintering beetles occur outside fields and typically invade field edges, so walking the field edge once a week will easily identify any potential problems. Despite the "Colorado" name, there are less problems with this insect in the state than in most places in the United States and Europe, and it is absent in Colorado's potato-growing areas of the San Luis Valley and Western Slope, even though there are no pesticide-resistant strains. There are no pheromone traps for Colorado potato beetle. A bigger worry would be potato psyllids, which are far more damaging to potato plants in the state than the misnamed Colorado potato beetle. ***
