Signs of Flea Bites

Flea bites on humans will generally appear as small, red bumps, sometimes with a halo around them. They most commonly occur on people’s legs, especially their feet, calves, and ankles. These bumps can be intensely itchy, and scratching them causes more damage to the skin, meaning bacterial infection can develop in the area. Flea bites typically last around 1 to 2 weeks, depending on the severity of the bite. If you have severe reactions to the bites or suspect an infection, contact your doctor for advice on treatment.

How to Prevent Flea Bites

The best way to prevent flea bites on humans is to make sure your cat is regularly treated for fleas. This can be done with topical treatments, shampoos, and oral medications. Regular grooming and vacuuming of the home are also important steps in controlling fleas and making sure any other pets in the household are up to date with suitable flea control. Contact your veterinarian for advice on the best treatment options.

How to Treat Flea Bites

Vacuuming will help reduce flea numbers, and a household flea insecticide spray is usually needed. Follow all treatment guidelines from your veterinarian and the manufacturer’s instructions carefully to avoid any toxic effects.
