Best Mosquito Repellents for Cats of 2025

"I found that it takes a bit to kick in, but once it does, it really works! I’ve purchased these collars for all my cats, and I love the smell and color. After struggling with a bad flea problem, these have made a significant difference. I’ll definitely keep buying this product!"

"I had high hopes for this collar, but it barely lasted a week on my cats. They quickly got fleas and ticks again. I wish there was a refund option for opened and used products."

"This collar is a game-changer for my cat who hates collars. The quality is excellent, with no rough edges, and it fits her comfortably. She’s not trying to take it off, and I haven't seen her scratching much, so I believe it’s effectively killing the fleas. Plus, I appreciate that it’s made with essential oils—much safer than harsh chemicals!"

"I run a cat rescue and often receive strays that are infested with fleas. After combing them and bathing with Dawn dish soap, I use Wondercide to spray and massage it all over. This technique works 100%! I also spray blankets and furniture. It's gentle and has an amazing smell. I prefer the peppermint scent, but I enjoy all of them. I do have to switch to a different spray bottle sometimes, but that doesn't affect my 5-star rating."

"I didn't like the cedarwood scent at all, so I switched to lemongrass after trying the rosemary, which still smelled like cedarwood. However, the lemongrass scent is fantastic! It starts strong but fades quickly, and it really works against fleas. I was skeptical of the positive reviews, but I can confirm this stuff is effective. The only downside is that it’s difficult to wash off my hands."

"I started using Wondercide due to concerns about harsh flea treatments. I love that it repels fleas and ticks before they bite my dogs. This product eliminates worries about potential side effects from traditional treatments. It provides a safe barrier against pests, and I trust it completely. The spray is easy to use, produces a fine mist, and the bottles are high quality. I will continue using this for all my dogs."

"I really appreciate the non-toxic nature of this product, especially since I have 4 cats dealing with fleas. It works fairly well, though I've noticed that it seems to weaken a bit towards the end of the month. My pets do end up smelling like peppermint oil, and there’s a slight stickiness where applied, but I’m still a regular customer of Wondercide."

"I was optimistic about this product because I prefer using natural solutions for my animals. Unfortunately, it didn't meet my expectations at all. Despite applying it as instructed and waiting, my cats were still crawling with fleas and I even found a tick. I initially tried the cedarwood spray, but my cats absolutely hated it, so I switched to the peppermint spot-on version. They tolerated it better, but it ultimately failed to work. I ended up spending almost $50 for nothing."

"After many attempts to get rid of fleas, I applied this product to my other cat following several whole-house treatments. I'm happy to report that I haven't seen a flea in several days! I plan to keep using Wondercide products moving forward."

"I recently tried Hartz UltraGuard Topical Flea & Tick Prevention for Cats and Kittens, and I am thoroughly impressed with the results. This product is incredibly easy to apply, making it a hassle-free experience for both me and my cat. In just a few days, I noticed a significant reduction in fleas and ticks, and my cat seems much more comfortable and happy. The three-month supply offers great value, ensuring my pet is protected over an extended period without frequent reapplication. I appreciate that it's specifically formulated for cats, providing peace of mind that it's safe for my furry friend. Overall, Hartz UltraGuard has proven to be an effective and reliable solution for flea and tick prevention. I highly recommend it to any cat owner."

"As a cat owner, I prioritize my pets' well-being, and Hartz UltraGuard Topical Flea & Tick Prevention has been a reliable solution for keeping fleas and ticks away. The application is straightforward and hassle-free, and it provides up to 30 days of protection, giving me peace of mind. I appreciate that it’s designed specifically for cats and kittens, ensuring that it doesn’t cause discomfort or irritation. The affordability of this product is a plus, especially compared to other options on the market. Overall, I highly recommend Hartz UltraGuard for fellow pet owners."

"I URGE YOU NOT TO buy this! I made the mistake of choosing it due to the price. My cat got fleas, and although I initially decided to use a different treatment, I ended up using this one after running out. The strong scent bothered my cat immediately. After applying it, she started sneezing and scratching, and soon she was running around yowling. I immediately regretted using it. Even after an hour, she seemed teary-eyed. I contacted Amazon, but they couldn't help me, and the company seems highly suspicious. I feel this product may harm your pet. Please stay away!"

"I had previously used this brand for my dogs when we couldn't afford oral medication. It worked perfectly and eliminated fleas immediately, but applying it to my cat was quite the adventure! Two-person job for sure, and after repeated applications, we opted for the oral treatment instead. The spray worked wonders in our home too!"

"After battling a flea infestation for too long, I found this amazing product that killed fleas almost instantly. I even sprayed it on my cat, and she was much happier afterward. The smell is strong, but the relief from those horrendous fleas is absolutely worth it!"

"This product is a game-changer! I've been cleaning daily and changing sheets, but this spray truly helped ease our flea situation. The only downside is that it irritates the eyes a bit when spraying, but it really works!"

"I should have gotten these a long time ago. No more fleas and they have calmed all three of my cats down tremendously. I love the smell, not chemically, and they honestly work."

"This collar is a convenient and safer alternative for cat owners who prefer natural options. I recommend consulting a veterinarian to find the best flea and tick prevention for your cat, especially if you have severe infestations."

"Putting on this collar was a breeze. My cousin's cat was very comfortable wearing it, and after a few weeks, she noticed fewer signs of fleas. It works just as well as some more expensive collars."

"I found these flea collars to be inexpensive yet surprisingly effective. When they arrived, I was pleasantly surprised to see they matched the quality of the more expensive collars I used to buy. So far, they seem to be doing the job well!"

"This collar is a great natural option for flea and tick prevention. It's convenient and I appreciate the focus on safety for my cat, but I understand that its effectiveness might depend on the infestation level and my cat's sensitivity. I plan to consult my vet for the best advice."

"I absolutely love this collar! It fits my cat perfectly due to its adjustable design and is made from a soft material that doesn’t irritate her skin. After a few weeks of use, I noticed she's flea-free, and it even protects my home from fleas!"

"I recently tried the Hartz Nature Shield Flea and Tick Cat Spray for my feline companion, and I must say I'm impressed with the results. This spray provides a natural alternative to harsh chemicals, which I really appreciate. After using it as directed, I've noticed a significant decrease in fleas and ticks, making my cat comfortable and itch-free. The ease of use with the fine mist spray bottle was a pleasant surprise, and the nice scent adds to the overall experience. I highly recommend this product to fellow pet owners!"

"As the owner of an indoor/outdoor cat, I really liked this spray. The clean and light scent is refreshing, and I love that the ingredients are all natural and safe for both my pets and children. The spray was very easy to use, and I haven’t noticed any issues with fleas or ticks since I started using it. I will definitely purchase this item again!"

"I had a tough time getting the spray to work at first, but after some persistence, it finally functioned. However, I found the nozzle to be a complete nightmare to deal with. Once I managed to spray it, it didn’t seem effective against the fleas. It might work for a light application before a walk, but I felt the claim of it killing fleas was misleading. I’d suggest looking for another product."

“Initially, I was skeptical, but I had to try something since I was constantly removing ticks from my outdoor cats. After a week, I haven't seen any ticks, and I couldn't be happier!”

“I bought this for my two cats, and while it worked well initially, after a month, they lost fur around the collar area. I’m not sure if it was irritation or an allergic reaction. Unfortunately, they are covered in fleas again.”

“I have four cats, and they all smell wonderful and are protected well with this product. It’s easy to use, lasts even when wet, and I’m giving it a solid five stars!”

"I live in the South, where fleas are everywhere. We switched from a brand-name flea repellent to this natural product for our cats' health, and it worked like a charm! Although it caused a bit of dry skin, coconut oil helped. We haven't seen any fleas since using Alzoo!"

"I've been using these drops for five years on my cats. They are all-natural and keep fleas away for three months. I have severe scent allergies, and these drops don't bother me at all. I wouldn't use anything else!"

"I researched safe essential oil flea repellents and found this one. My ragdoll cat with a weak immune system had no side effects after using it, and it was effective. I recommend pairing it with a skin and coat health supplement for added protection."
