Best Dog Flea Sprays of 2025

"I can't believe it! Vet's Best really works! After struggling with fleas for years, I finally found a solution. I sprayed every inch of my home, and within no time, we noticed a difference. The scent is strong, but it’s mostly pleasant. I keep several bottles around just in case!"

"I don’t usually leave reviews, but this spray is amazing! It quickly killed the fleas on my dog, and I appreciated the two different spraying options. The minty scent is nice, and it didn’t stain any of my furniture. After days of thorough checks, I haven't seen any fleas. I highly recommend it!"

"This spray has helped me gain control over the flea problem in my house. After vacuuming, I use it in corners and under the furniture. The minty smell is strong but natural, and my cats seem indifferent to it. I’m ordering another bottle soon to keep the fleas at bay!"

"This Veterinary Formula Flea & Tick Spray has been a handy addition to my pet care routine. With four dogs, I constantly battle fleas and ticks, and this spray has helped me manage the problem effectively. The fine mist spray nozzle made it simple to cover my Blue Heeler, Harvey, and my tiny Chihuahua mix, Tiger, without soaking them. I was a bit worried about Tiger's sensitivity, but he tolerated it well. I didn't notice any strong or unpleasant odors, which is a significant improvement over other sprays I've used. Moreover, I observed a quick reduction in scratching and biting after application. This product works effectively without harsh chemicals and is safe for puppies over 12 weeks. Overall, this is a reliable spray that I feel good about using on my dogs."

"I was almost embarrassed to order the Veterinary Formula Flea and Tick Shampoo after discovering a flea infestation. With my experience in pet ownership, I had never dealt with fleas before. After a quick call to the vet and some pest control, I decided to try this shampoo. My first impression was that it has a mild citrusy scent, much better than I expected. It lathered well, making it easy to reach any fleas hiding in my dog's dense coat. There were no skin irritations, and my dog's fur felt salon soft after using it. I did notice a couple of fleas in the bathtub, but overall, the shampoo effectively removed them. It worked best when combined with other flea prevention treatments, and now my pets are flea-free!"

"I really like this shampoo! No harm came to my cat, and it has a pleasant smell. It effectively removed all the fleas, making it a great choice for pet owners like me!"

"I had a flea infestation that was driving me crazy. After trying several products without success, I found this Hartz product and it really works! The scent is quite mild; just open the window for a few minutes and it's gone. It's about 1/10th as strong as Pinesol, so it's very tolerable."

"After using this spray on my rugs and around my cat's play areas for 6-8 weeks, I can confidently say my cats are now flea-free! It works, and I'm thrilled to have a flea-free environment."

"I've been applying this flea control spray on my cat for a few days now, and I've noticed fewer fleas almost immediately. My cat seems much happier. The scent is pleasant, which is a plus. The only minor issue is that the nozzle feels a bit flimsy, so I have to handle it with care. Overall, I'm very pleased with the results—my cat is flea-free so far!"

"I sprayed my dog outside, and the smell was super strong, but it worked! My dog was so happy running around, and we finally got rid of those monster fleas. We're all much happier now!"

"After a visit to the in-laws, my dog was covered in fleas. I treated her with this product, and I'm thrilled to say we never saw those fleas again. If you catch it early, this stuff works great!"

"I've got two small Maltese dogs, and I was really hopeful about this product. Unfortunately, it did absolutely nothing to help with the fleas. They were still itching and had live fleas crawling on them even after using the spray."

"I noticed my cats were itching, so I decided to try this product. Within 10 minutes, the fleas were falling off and dead. I recommend keeping them in a ventilated bathroom to avoid mess. The only downside is the smell, which is a bit overwhelming, but overall, this is the best product I've ever used. I'm keeping a bottle at home just in case."

"After struggling with fleas for months using Frontline Plus and Advantage II, I bought this spray. It killed the fleas immediately upon application. I brushed my cats afterward, and there were no fleas at all. It's been 4 days, and I haven't seen any since! The cats seem relaxed and normal, which is a huge relief. The scent is stronger than I prefer, but it makes me feel confident it's working."

"I used this on my dog who had fleas and even found a tick. Now, she's completely pest-free, and it’s been great. She goes outside frequently and remains pest-free. The scent is also very pleasant, which I appreciate."

"I'm halfway through my first bottle, and I like it because it doesn’t smell too strong and it works well against fleas. I’ve noticed they sometimes come back in about two weeks, but I believe that’s due to them being in the lawn. The sprayer could be better, as it’s hard to push when wet, but I will buy it again."

"This tonic is fantastic! I was surprised at how well it worked, especially since it's an all-natural product. I applied it with a cotton ball to my dog, and the results were amazing. I rinsed her off after about 20 minutes, and I was able to wash away several fleas. She has been so much happier since, scratching only a few times a day now. We are delighted with the results!"

"I've been using this product on my dogs for years in Florida’s summer. It effectively keeps mosquitos at bay, and it’s pet-friendly. I love this product!"

"I run a cat rescue and often receive strays needing care. Wondercide has been a lifesaver for many cats suffering from fleas! After bathing them with Dawn and using Wondercide, I see incredible results. I love the peppermint scent, but all the scents are great!"

"After trying the cedarwood and rosemary scents, I wasn't impressed. They smelled similar and weren't liked at home. However, when I switched to lemongrass, I was thrilled! It smells great and really works on fleas. I didn't believe the glowing reviews at first, but now I see they're true!"

"I started using Wondercide due to concerns over harsh chemicals in traditional flea treatments. I appreciate that this product repels fleas and ticks before they bite, ensuring my dogs are safe. I highly recommend it for anyone wanting to care for their pets naturally."

"I was initially skeptical, but I was desperate, so I decided to give it a shot. To my surprise, I didn’t get a single mosquito bite all summer! After saturating my yard, I did a second application about a week later, and it lasted from July through September. The distinct smell is pleasant enough, and once it dries, it doesn’t linger. I didn’t use it indoors due to my family’s sensitivities, but it really worked outside. I would definitely recommend it!"

"This was my first experience using the product on my almost acre property. After a bad tick incident with my puppy, I wanted something safe for him. I found this product for $10 and decided to try it. I was thrilled with the results! I sprayed it just before dusk, and the next day, the mosquitoes were completely gone! There were no ticks in the weeks following either. For the price, I think it’s worth a shot!"

"I've been using this product for a while now, and I must say, it has helped keep the flea population in check. I was struggling with fleas until I started applying this every two weeks. It’s easy to use—just attach to the hose and spray. While I wouldn't rely on it alone for a serious infestation, it does a decent job for preventative measures."

"I know exactly how you feel. I'm currently dealing with a flea infestation in my 5000 sq ft home. My two cats have run of all 19 rooms and four floors, so it's taking longer than it might for someone with a smaller space. I've gone through three bottles of this spray, and it definitely works! I had one chair where my cat left fleas, and when I sprayed it, they died instantly. For larger homes, I’m not sure if a plant-based product is enough. My plan is to bomb the attic and basement soon while continuing to spray daily elsewhere. I’ve cleaned more this past month than I have all year! After six weeks, I can see improvement, but it’s still a struggle. I’m vacuuming every day and using a strong cleaner. I still find a few fleas here and there, but I’m hopeful!"

"We found a stray kitten with fleas, and after giving him a bath, I noticed fleas in our living area. I decided to buy this spray, and within a day, we no longer had any flea issues! It has a refreshingly strong lemon scent that kept our home smelling great all week. I’m really pleased with the results!"

"I was excited to try this product based on the positive reviews, but I was shocked to find no warnings that pets should be kept out of the area while using it. My three pets became seriously ill after application, displaying symptoms like vomiting and diarrhea. We had to rush them to the vet during a pandemic! Thankfully, they’re okay now, and our house is flea-free, but I would never recommend this product to anyone. It's just not worth the risk to my pets!"

"I've been using this product for about four years. It provides great relief for my German Shepherd, especially from flies that target his ears. The smell is not bad, unlike other sprays. Even when neighbor dogs visit, it helps manage the fleas."

"This product outperforms many high-priced alternatives I've tried. I'm very pleased with its effectiveness!"

"I apply this spray to our pigs, chickens, turkeys, and pets. It completely keeps fleas, ticks, and mites away! I even spray it on my pant legs to keep ticks off, and it does the job well. Plus, no skin irritation has been observed."
