Baits and sprays are not the same and they are applied in different pest scenarios. A professional knows which one will work best in the removal of a specific type of pests or bugs. Spray products give faster results, but they need to be ingested by the pests or bugs for the best results. Baits work best in situations where the entire colony of a pest such as the ant needs to be destroyed. It is for the pest control service to determine which should be applied where.
