Fleas are common pests that infest dogs, cats, and even their owners. These small insects feed on the blood of their hosts. Measuring about one-eighth of an inch long, fleas are tiny, wingless creatures capable of jumping nearly 150 times their body length.
Despite their small size, fleas are very quick, making them difficult to detect. Some pets are more sensitive to flea bites than others. The saliva from fleas can trigger allergic reactions, leading to increased itchiness. You may notice your pet scratching more frequently. A closer examination of your pet may reveal scabs or “flea dirt,” which consists of small, dark specks that are actually flea faeces made up of digested blood from the host.
Fleas are a common nuisance for pet owners, and if your dog has them, it’s essential to take action quickly. These tiny parasites can cause itching, skin infections, and even transmit diseases. The big question is: should you handle the problem yourself or seek professional help?
In this article, we’ll explore both the DIY and professional approaches to flea removal so you can decide which is best for your dog.
Understanding Flea Infestation
Fleas are tiny, fast-moving insects that survive by feeding on your dog’s blood. A single flea can lay up to 50 eggs per day, leading to a rapid infestation. If not treated, fleas can cause:
- Severe itching and discomfort
- Skin infections and hot spots
- Flea allergy dermatitis (FAD), a common allergic reaction
- Anaemia in severe cases, especially in puppies
- Transmission of tapeworms if your dog ingests a flea carrying the parasite
If your dog is scratching excessively or has red, irritated skin, fleas could be the culprit. You may also notice flea dirt (black specks) on their skin, which is actually flea faeces.
Although dogs don’t need a specific vaccine for fleas, they do require regular vaccinations against diseases like distemper, parvovirus, and rabies, and flea prevention is essential to protect them from parasites and associated health risks.

DIY Flea Treatment: Can You Handle It Yourself?
Many pet owners prefer to treat fleas themselves due to cost savings and convenience. Here are some common DIY methods:
1. Flea Shampoo and Baths
Giving your dog a flea bath using specially formulated shampoos can kill adult fleas. However, flea shampoos have a limited residual effect, meaning they won’t prevent new fleas from jumping on your pet.
Pros:
- Quick and easy to use
- Provides immediate relief
- Readily available at pet stores
Cons:
- Doesn’t kill flea eggs or larvae
- May dry out your dog’s skin if overused
- Requires frequent reapplication
2. Topical Flea Treatments
Spot-on treatments like Frontline, Advantage, or Revolution are applied to your dog’s skin and provide long-lasting flea control. These treatments typically kill adult fleas, eggs, and larvae.
Pros:
- Provides protection for up to a month
- Kills fleas at all life stages
- Easy to apply
Cons:
- Some dogs may have skin reactions
- Needs precise application to be effective
- Takes a few hours to fully absorb into the skin
3. Oral Flea Medications
Oral flea treatments, such as NexGard and Bravecto, kill fleas quickly by entering your dog’s bloodstream. When fleas bite, they ingest the medication and die within hours.
Pros:
- Fast-acting and effective
- No mess like topical treatments
- Some options last up to 3 months
Cons:
- May cause digestive upset in some dogs
- Requires a prescription in many cases
- Does not repel fleas—only kills them after they bite
4. Flea Combs
A flea comb can help physically remove fleas and flea dirt from your dog’s fur. This method is best for mild infestations or as a supplementary treatment.
Pros:
- Chemical-free and safe
- Helps detect fleas early
- Can be used daily
Cons:
- Time-consuming
- Does not kill fleas—only removes them
- Ineffective for severe infestations
5. Home and Yard Treatment
Fleas don’t just live on your dog—they infest your home and yard. Vacuuming frequently, washing pet bedding, and using flea sprays or diatomaceous earth can help break the flea cycle.
Pros:
- Reduces reinfestation risks
- Safe if done correctly
- Prevents fleas from spreading
Cons:
- Requires ongoing effort
- Some chemical sprays can be harmful to pets
- May not be effective in heavily infested areas

When to Call a Professional for Flea Treatment
If DIY treatments aren’t working or the infestation is severe, it’s time to call in the professionals. Here’s what they can do:
1. Veterinary Flea Treatments
A vet can prescribe stronger flea medications, including injections, medicated shampoos, and fast-acting oral treatments. They can also check for secondary infections and allergic reactions.
Best for:
- Dogs with severe flea allergies
- Puppies or senior dogs that may not tolerate certain treatments
- Recurring flea infestations despite DIY efforts
2. Professional Pest Control Services
If fleas have spread throughout your home, Pest Control Brisbane.com can treat carpets, furniture, and outdoor areas with insecticides that kill fleas at all life stages.
Best for:
- Severe home infestations
- Multiple pets with fleas
- Houses with a high risk of reinfestation
DIY vs. Professional: Which One Should You Choose?
Factor | DIY Approach | Professional Help |
---|---|---|
Effectiveness | Works for mild to moderate infestations | Best for severe infestations |

Time Required | Requires consistent effort | One-time treatment with follow-ups |

Preventing Future Flea Infestations
Whether you choose a DIY or professional approach, preventing future flea problems is crucial:
- Use Flea Preventatives: Monthly flea treatments (oral or topical) are the best way to prevent fleas.
- Maintain Regular Grooming: Bathing and brushing your dog regularly can help spot fleas early.
- Keep Your Home Clean: Vacuum frequently, wash pet bedding, and use flea sprays as needed.
- Treat All Pets in the Household: If one pet has fleas, others likely do too. Treat them all at the same time.
- Control Fleas in Your Yard: Mow your lawn, remove debris, and consider pet-safe insecticides to reduce flea populations outside.
Final Thoughts
If your dog has fleas, acting fast is key to preventing a full-blown infestation. The DIY approach can work well for mild cases, but professional help may be necessary for more severe situations. A combination of effective flea treatments, home cleaning, and prevention measures will keep your dog flea-free and comfortable.
