What to do if you can't get rid of fleas on your dog

Why do fleas keep coming back

One of the biggest reasons flea problems persist is because adult fleas only make up a small percentage of the total infestation - Only 5% of the fleas you see live on your dog, whilst the other live and breed in your home. Most of the hidden fleas in your home are not even fully grown, they are immature fleas such as the eggs, larvae, and pupae.

A single flea can lay dozens of eggs every day. These eggs fall off your dog and settle into carpets, bedding, furniture, cracks in flooring, and even inside your car. Over time, the eggs hatch into larvae and eventually become adult fleas.

This means that even if you kill every flea currently on your dog, new fleas can continue emerging from your environment for weeks or even months. And this is why many pet owners think the treatment failed when they continue seeing fleas after applying medication. In reality, newly hatched fleas are often jumping onto the dog from the environment.

Spot on treatments can also fail if they are applied incorrectly. The medication should usually be placed directly on the skin rather than on the fur. If your dog has a thick coat, part the hair carefully before applying. And after applying your dog’s flea treatment, make sure to not get them wet for 48 hours as this can also wash away the flea drops. 

Oral flea medications are often preferred for stubborn infestations because they are less likely to wash off and can begin killing fleas quickly.

Some flea populations have also developed resistance to older products. If you have been using the same treatment for years without success, it may be time to speak with your vet about newer options.

You need to treat every pet in the household

One of the most common mistakes people make is treating only the dog that appears to have fleas.

If you have cats, other dogs, or small pets in the home, they may also be carrying fleas even if they are not scratching excessively. Fleas can move easily between animals, allowing the infestation to continue.

Every pet in the household should be treated at the same time using the right flea products. Never use dog flea treatments on cats as some dog flea medications contain ingredients that are highly toxic to cats.

Consistency matters. Even indoor pets should receive treatment during an infestation because fleas can survive inside homes year-round.

Use flea control products in your home

In severe infestations, cleaning alone may not be enough.

Home flea sprays and foggers can help reduce flea populations, especially when combined with pet treatments and regular cleaning. Products that contain insect growth regulators (IGRs) are especially useful because they stop flea eggs and larvae from developing into adults, like Itch Flea House Spray. 

However, flea bombs and foggers are often less effective than people expect because the chemicals may not reach hidden areas where fleas live.

Targeted sprays are usually more effective for carpets, furniture, and baseboards. Always follow label instructions carefully, especially around children, pets, fish tanks, and food preparation areas.

If the infestation is severe or keeps returning despite your efforts, hiring a professional pest control service may be worthwhile. Professional exterminators can treat hidden areas more effectively and may identify outdoor sources of infestation that you missed.

Keeping your garden trimmed and clean can help reduce flea habitats. Alongside this, wash outdoor pet bedding and regularly clean kennels or dog houses. You may also want to consider outdoor flea treatments if your dog spends a lot of time outside.

Wildlife such as raccoons, stray cats, foxes, and rodents can also carry fleas into your garden. If wildlife activity is high around your home, addressing those issues may help reduce recurring infestations.

A flea comb can help remove fleas, flea dirt, and eggs from your dog's fur. Focus on areas around the neck, tail, belly, and behind the ears. Drop captured fleas into hot soapy water to kill them. Here’s what a good comb looks like!

Watch for signs of flea allergy dermatitis

Some dogs are extremely sensitive to flea bites. Even a small number of fleas can trigger intense itching, redness, hair loss, and skin infections. This condition is known as flea allergy dermatitis.

Vets recommend keeping your dog on flea treatment all year round if they suffer from flea allergies - This is because it is safer to avoid fleas all together, than risk a flea infestation which could lead to serious infection.

Dogs with flea allergies may:

• Scratch constantly
• Bite or chew their skin
• Develop red, inflamed patches
• Lose fur around the tail or lower back
• Get scabs or hot spots
