The answer to 'what attracts flea' is that fleas are attracted to warm-blooded hosts, like pets and humans. Fleas feed on the blood of their hosts and thrive in environments with high humidity and temperatures between 70-85°F. Common signs of a flea infestation include seeing the small, dark-colored insects on your pet, excessive scratching, and finding flea dirt (dried flea feces) on your pet's fur or in your home.
Fleas can be difficult to get rid of, as they reproduce quickly and their eggs and larvae can be hard to detect. Treating a flea problem requires a multi-pronged approach, including treating your pet, your home, and your yard. For severe infestations or if you're unsure how to properly address the problem, it's best to call a professional pest control technician who can properly identify the issue and recommend the most effective treatment plan.
