Fleas are small, wingless, parasitic insects that live off the blood of their hosts. They can infest pets, livestock, wild animals, and humans. Flea bites can cause irritation, inflammation, and discomfort. Knowing how to identify fleas and flea infestations is important for controlling these pests. There are several ways to determine if fleas may be present, including looking for signs of fleas or flea dirt, using a flea comb, observing pet behavior, and checking areas where fleas congregate. Being able to recognize a flea infestation early allows prompt treatment to get rid of the fleas and provide relief from bites.
Signs of Fleas and Flea Dirt
One of the most obvious ways to check for fleas is to look for the fleas themselves or their droppings, known as flea dirt. Adult fleas are only about 1/16 to 1/8 inches long, so they can be difficult to see. Their bodies are flat, hard, and smooth. Fleas are usually dark brown in color and can jump long distances. To spot them, part the fur and look near the skin for fleas jumping or running around.
Another sign of fleas is flea dirt, which is essentially flea feces. Flea dirt consists of digested blood and appears as tiny dark specks, similar to ground pepper. These pepper-like grains will be present in areas where pets sleep, rest, or groom themselves. Flea dirt can be distinguished from regular dirt by placing it on a wet paper towel. If the specks dissolve into reddish spots, it is confirmation of flea dirt. The blood in flea feces causes the color change when wet.
Using a Flea Comb
A flea comb can also help reveal the presence of fleas. Flea combs have narrow, close-set teeth that are able to trap fleas and flea dirt as you comb through the haircoat. To use one, start combing around the neck and head area, then work down the body against the direction of hair growth. This pushes fleas down towards the base of the hair where they become trapped in the comb.
Check the comb after each pass to look for fleas and black flea dirt caught between the teeth. It’s a good idea to have a container of soapy water nearby to dip the comb into to kill any live fleas. The soap causes the surface tension of the water to break and drown the fleas. Repeat the combing process in short sections until you’ve thoroughly combed through the entire coat. Finding live fleas or flea dirt signals there is likely an infestation needing treatment.
Pet Behavior Changes
Flea bites commonly cause pets to scratch, lick, chew, or bite at their skin, often intensely and excessively. This is because flea saliva contains substances that trigger severe itching. If your pet starts overgrooming, scratching, chewing, or seems generally restless and uncomfortable, flea bites may be the culprit. Also watch for signs of hair loss, red irritated skin, scabs, and hot spots, which can develop from frequent scratching and biting. Pets may also try to rub or scratch against furniture or the floor to relieve the itchiness.
Some animals can also become lethargic and depressed when suffering from anemia due to flea infestation. Fleas feed on blood, so heavy infestations can cause detectable blood loss. Young or small pets are most vulnerable to flea anemia. If your pet displays lethargy combined with the scratching behaviors, suspect flea bites as the reason.
Areas Where Fleas Live
To further pinpoint flea problems, inspect places fleas are likely to live and breed when not on their host. Fleas thrive in warm, humid environments. When not feeding, they congregate in areas like carpets, rugs, bedding, upholstered furniture, pet beds, and cracks in floors or tile. Concentrate on protected areas around baseboards, between cushion seams, under furniture edges, and where your pet sleeps or hangs out.
Use a high-powered flashlight to scan for fleas, eggs, or flea dirt in these spots. You may see fleas scurrying away as you disturb their hiding places. The eggs appear as tiny white oval specks, while flea dirt looks like pepper flecks. Finding evidence of fleas in these areas means you’ll then need to treat the environment as well as the pet to gain control.
Outdoor Risk Factors
Certain outdoor environments raise the risk of pets picking up fleas. Fleas thrive outdoors in warm, humid conditions, especially in areas with tall grass, brush, or wildlife. If your pet goes camping, hiking, spends time in wooded or grassy areas, or is around wildlife, they are more likely to encounter fleas. Yards or neighborhoods with stray or wild animals like raccoons and opossums also up the odds. If your pet picks up even one flea outdoors, this can start an infestation at home. Be extra diligent checking for fleas after high-risk outdoor activities or potential wildlife encounters.
Preventing Fleas
Routine use of flea control products can help prevent flea problems from developing in the first place. There are many effective and convenient oral and topical products that kill and repel fleas. Consult your vet for recommendations of good flea preventatives based on your pet and situation. Flea collars, sprays, shampoos, powders, and foggers help reduce environmental flea populations when used properly as part of an integrated pest management plan.
Keeping your home clean and free of debris will help discourage flea infestations. Regularly wash pet bedding in hot soapy water to destroy flea eggs and larvae. Vacuum floors daily using a vacuum with a HEPA filter to remove eggs and immature fleas from carpeting and floors before they can develop into biting adults. Promptly dispose of the vacuum bag after use. Mowing, raking leaves, removing brush, and clearing clutter in yards removes potential flea breeding spots.
Treating a Flea Infestation
If you confirm that fleas are present, you’ll need to treat both your pet and the home environment thoroughly. On your pet, use flea control products recommended by your vet; do not rely solely on over-the-counter flea collars or shampoos. Follow all label instructions carefully. For the home, concentrate on areas the pets frequent. Thoroughly vacuum then dispose of the bag to clear some adult fleas, eggs and larvae.
Wash all pet bedding and throw rugs in hot soapy water. Use an insecticidal spray or fogger made for flea elimination in the home as directed on the product labels. Work carefully around furniture, carpets, baseboards, and floors. It often takes perseverance to fully rid a home of an established flea infestation. But with diligent treatment of pets and premise, fleas can be successfully controlled and eliminated.
When to Seek Professional Help
In severe flea infestations that are proving difficult to manage, veterinary and professional pest control assistance may be beneficial. Your vet can recommend advanced flea elimination products and treatments to safely and effectively treat the pet patient. They may also offer additional suggestions for environmental control in the home and yard.
For serious home infestations, professional exterminators can use specialized equipment and insecticides to thoroughly treat where fleas are lurking. They also know the most effective products and methods to rid a property of entrenched flea populations. While fees apply for these services, they may provide theLEVEL, dramatic results needed for flea-free living after struggling to control the pests.
Signs of Flea Bites on Humans
Fleas do sometimes bite and feed on people, especially in homes with heavy pet flea infestations. Flea bites on humans look similar to other insect bites. They appear as small red bumps, often in groups of three or four. The bites are usually around the ankles, legs, or lower body as this is where fleas can readily access skin.
Flea bites are extremely itchy, much more so than mosquito bites. The severe itching results from components in flea saliva. Flea bite reactions on people may last for a week or more. Try not to scratch as this can lead to infection. Bathing with oatmeal or baking soda can help alleviate itching. Topical anti-itch creams containing pramoxine or hydrocortisone also offer relief. If bites become swollen or infected, see your doctor.
When to Call a Doctor About Flea Bites
Most mild flea bites can be managed at home. But call your doctor if bites exhibit signs of a more serious reaction or infection. Seek medical care for bites if you experience:
- Intense swelling at the bite site
- Oozing or weeping from the bite
- Lymph node swelling near the bite
- Streaking redness from the bite
- Fever, headaches, muscle aches, nausea, or vomiting
- Signs of a skin or systemic infection like pus, worsening redness, or flu-like illness
These can indicate a bacterial infection, allergic reaction, or other medical issue needs diagnosis and proper treatment. Flea allergy dermatitis triggered by bites may also require medical care to ease the itching and clear skin reactions.
Home Remedies for Flea Bites
Home treatment can help soothe most flea bites. Follow these tips for managing flea bites at home:
- Wash bites with soap and water to remove allergens and decrease itching.
- Apply cold compresses, aloe vera gel, or an ice pack to reduce swelling and irritation.
- Avoid scratching bites to prevent infection.
- Try oral antihistamines containing diphenhydramine or loratadine to relieve itching.
- Use antibacterial creams or ointments on broken skin to prevent infection.
- Apply baking soda or milk of magnesia paste to alleviate itching.
- Try a cream with hydrocortisone, pramoxine, or calamine to ease inflammation.
Most importantly, treat pets and premises to eliminate fleas and avoid further bites. Protect skin from scratches and cover bites if needed until fully resolved. See a doctor promptly if you have any signs of infection or concerning reactions following flea bites.
