Any sign of disturbance to the unit (predators, fire ants, etc.)?
If you encounter problems please check the unit for any signs of disturbance. One common concern is fire ants. To detour fire ants prepare the site one week in advance before placing and apply granular fire ant preventer to the site where the Surrogator will sit. Once the unit is in place fire ant preventer can be applied around the perimeter of the unit at a distance of two feet.
