1. Moisture: In order to survive and grow, fleas require a humid atmosphere.
2. Shade: The invaders thrive in locations with overgrown vegetation, trees, bushes, and structures like patios or decks because they avoid direct sunshine.
3. Hiding places: Untidy places such as mounds of waste, thick grass, and leaves provide a haven for fleas.
4. Fleas are brought into your environment by stray dogs or cats, squirrels, and raccoons.
5. Food sources: Fleas that feed on blood are drawn to warm-blooded creatures, such as pets. If there are many of hosts around, fleas are more likely to settle down in your yard.
6. Warm weather: Fleas are a nuisance throughout the summer since they love warm weather.
