The answer to 'flea season' is that fleas are typically most active during the warmer months of the year, typically from spring through fall. Flea populations tend to peak in late summer and early fall, when the weather is warm and humid - conditions that allow fleas to thrive and reproduce quickly.
Fleas are small, wingless insects that feed on the blood of their hosts, which can include pets, wildlife, and even humans. They can be a major nuisance for homeowners, as they can infest homes and cause itchy bites. Flea season is the time of year when homeowners are most likely to encounter flea problems and need to take steps to prevent and control flea infestations.
