Best Repellent Spray Concentrates of 2025

"I've tried several products to keep rodents from eating wiring in my vehicle. Most have a terrible smell, but this one smells great and seems to work!"

"I had chipmunks and mice trying to nest in my lawn furniture cushions. After watering it down and lightly spraying, they never tried again."

"I mixed the solution as directed and applied it everywhere squirrels dig in my garden. Unfortunately, it did not work at all, but the company offered a full refund, which was impressive!"

"From the moment I saw this product on TikTok, I knew I had to try Bug MD for fleas, ticks, and roaches. I've tried so many products before, but this one lasted up to three months! My family noticed fewer bugs, and I’ve been ordering it from Amazon ever since. This product has truly saved my life!"

"I use this product for everything from tiny sugar ants to outdoor bugs trying to invade my home. I even spray it as a preventive measure in the spring. It’s a fantastic product!"

"After months of battling fleas on my indoor cats with no success, I decided to give this spray a shot. After just one night of spraying, I noticed a huge decrease in fleas. I’m still spraying regularly, but the results have been dramatic after three weeks!"

“I live in Florida, and during the summer, the mosquitos are awful. After trying Wondercide, I sprayed around my pool area, and **the mosquitos almost instantly disappeared! The cedar oil worked wonders, lasting the entire weekend, even with all the rain. I love that it’s a natural product, so there’s no worry about chemicals harming the bay.”

“After using this product for a few years, I find that a little goes a long way. I typically spray early in the season and then maintain every few days until I notice fewer mosquitos. I’ve had great success with this method, and it’s now my third bottle in about five years!”

“I was really hopeful about this product, but after spraying my yard for five days, I can confidently say it does not work for me. I still have mosquitos buzzing around, and it seems like I have even more insects. It's frustrating considering I spent $40 on it.”

"I had some stink bugs in my yard. After spraying, they were all gone from the grass and moved to my windows within 10 minutes. This stuff definitely works!"

"Living at a cabin in Alaska, I deal with swarms of mosquitoes. This product is a lifesaver! I can spray once in early June and stay essentially mosquito-free until the end of summer. I always keep a couple of bottles on hand because if I run out, I’m in trouble!"

"I started using this insect killer a few years back after my exterminator kept raising prices. I mix it in a 15-gallon sprayer and apply it around my home every six months. It effectively keeps insects outside, and I’m really pleased with the results!"

"I just moved to an acre in South Carolina, and with a dog and cat, I was worried about fleas and ticks. After spraying my deck and yard, I was amazed at how quickly the gnats disappeared. We could finally enjoy our outdoor space without being bothered!"

"After trying this product, I noticed a significant reduction in mosquitoes in my yard. I appreciate that it’s safe for my cats, and I can spray without worry. However, I did have to reapply after a week when fleas returned."

"When I got home from work, I found the fleas had gotten bad in my shop. I mixed a stronger solution and sprayed the areas where my dogs frequent. Unfortunately, instead of repelling them, it seemed they enjoyed the cedar scent. I was still overwhelmed by the number of fleas."

"I found that this product works to repel woodpeckers, but not as strongly as advertised. I had to double or triple the concentration to see results. I recommend applying it liberally and letting it dry on its own. I actually think it smells quite nice!"

"I bought two bottles to address a seagull problem. After cleaning the droppings and applying the mixture heavily, I was disappointed to see that 45 minutes later, seagulls returned. I even tried a heavier concentration twice, but it was a huge failure."

"I used this product as directed, but it didn't deter the birds at all. I wouldn’t recommend wasting money on it, although I could give it two stars because of its nice smell."

"I've had deer visiting my yard daily, but since using Liquid Fence monthly, I've seen no more plant damage. This is my second year using it, and I'm really satisfied with the results. It’s much easier than putting up a fence!"

"In my neighborhood, we often have up to 12 deer at a time. Liquid Fence has proven to be completely effective in keeping them away from my decorative plants. Just remember to reapply after rain or watering!"

"After years of losing my Hosta plants to deer and rabbits, I finally found something that works! Liquid Fence is a miracle; I just needed to be consistent at first. My landscaping has stayed beautiful all season. Highly recommended!"

"I started with a small 32-ounce bottle and quickly upgraded to the concentrate. I use even less than the recommended dosage, and it's still strong. I recommend adding it gradually to find your ideal strength. Definitely worth the money! However, I still have some fungus gnats due to my greenhouse."

"I really enjoy the peppermint smell. It effectively kills bugs while leaving a fresh scent. I've purchased it twice and am very satisfied with its performance."

"I mixed a higher concentration, using about 40% of the concentrate with 32 oz. of water. I sprayed it on my balcony to keep swarming wasps away, and it worked! It also eliminated ants at my front door."

"I initially bought this product to stop stray cats from triggering my security cameras, but unfortunately, it didn’t deter them at all."

"I got this for my girlfriend’s old house, where stray cats were using the perimeter as a litter box. After following the instructions and applying it for several days, I was thrilled to see the cats avoiding her property almost immediately!"

"This product has a really strong smell, and while it stains light fabrics, it definitely does the job of keeping the cats away!"

"I live in an area where deer eat everything, no matter what. I've tried various 'deer resistant' plants, but they always get mowed down. After switching between this product and another, it seems to finally work. The smell is awful at first, but it fades quickly for humans. The deer likely still smell it. I didn't believe the reviews about the smell, but they're true. I recommend pushing through that first day if you have a serious deer problem."

"This is my first Amazon review after years as a Prime member. This product is incredible! The deer used to devour everything, including supposedly deer-resistant plants. Since using Bobbex, I've only had one nibble on a plant. It's now October, and I've planted numerous flowers and shrubs without issue. I spray every 7-10 days and have even switched to a larger bottle. Highly recommended! Even the rabbits are staying away!"

"I live in Pennsylvania with a lot of deer in my backyard. I got this to protect my flowers and shrubs. Initially, it seemed to work, but I found myself reapplying weekly. It outperformed other sprays, but nothing beats a physical barrier. I even included a photo of a young deer eating my daylilies shortly after spraying."
