When is the best time to check for standing water that may breed mosquitoes?

The best time to check for standing water that may breed mosquitoes is after every heavy rainfall. This is because heavy rain can create new sources of standing water, which mosquitoes need for breeding. Mosquitoes often lay their eggs in areas where water collects, and after rain events, these locations can change or new ones can form. By regularly checking for standing water after heavy rainfall, mosquito control efforts can be more effective, preventing the establishment of new mosquito populations before they have a chance to emerge and spread.

During winter months or peak activity hours, conditions may not be ideal for breeding. Additionally, checking only at the beginning of summer may be too late, as significant breeding could already have occurred by that time due to spring rains. Regular checks following rainfall will help keep mosquito populations in check throughout the season.
