The answer to 'how often for ant control' is that most homeowners will need to treat for ants on a regular basis, typically every 2-3 months during the active season. Ants can be a persistent problem, especially during the warmer months, so regular preventative treatments are often necessary to keep them under control.
The frequency of ant control treatments can vary depending on the severity of the infestation, the type of ants present, and the effectiveness of the previous treatments. In some cases, monthly or quarterly treatments may be required, while in other cases, bi-annual or annual treatments may be sufficient. It's important to work closely with a professional pest control technician to determine the right treatment schedule for your home and ant problem.
