Rover ants have proven to be one of the more difficult ants to control. Due to the rapid range expansion of this species, it is a relatively new pest problem. Non-chemical or cultural controls should be considered for controlling these ants first. Infestations are often associated with moisture and or fungal decay. Correction of moisture problems within buildings and in mulch areas near buildings will help with control. Any wood that is severely damaged due to water should be replaced. Around the home, remove or treat nesting areas under landscape timbers or rocks.
They seem to be not attracted to many liquid or granular ant bait formulations. Find entry points on exterior of structure and seal if possible and/or treat with a contact insecticide. Gel baits and dusts may be used in electrical sockets for indoor control. If ants are in a void area, an aerosol may be used.
With Halloween just around the corner, its time for larger-than-life creepy, crawly creatures skittering across lawns, lurking in dark alleyways and dropping out of nowhere to frighten their hapless victims.
