What is it?
Pinhead-size brown bugs that feed on the blood of warm-blooded animals (often cats or dogs).
What to look for
Fleas don't fly but can jump from a pet onto carpeting and people. Bites appear as tiny red bumps or pustules, often on exposed skin below the knee and in a line.
What to do
Wash bites with soap and water, and apply an anti-itch cream. Discourage scratching, which can lead to infection.
How to prevent it
Talk to your vet about the best flea control for your pet; flea collars can leave chemical residues that are dangerous to kids. Use insect repellent when your child plays in a public area (like a park sandbox).
