I became concerned about the toxicity of most flea and tick edible meddls and collars. My dog has only had fleas once, and we use this product after laundering all the dog bedding. It eliminated fleas on carpets and dog bedding. We now spray the dog on the way outdoors during summer and fall when fleas and ticks are at their worst. Have never again seen fleas on the dog nor a tick. It's still a good eye to manually go through your dogs for because ticks are becoming more tenacious in New England states. Wonder side is a really great alternative to the potentially toxic flea and tick medications

I was looking for a long time for a non-toxic solution to protect my dog and after having no luck with several natural formulas I caved and rotated through several products (collars, sprays, topical solutions, etc.) sold at Fill-in-the-blank popular pet store (including some marked “natural”) and it shocked me to find the problem with fleas hitching a ride on my dog after a walk outside still persisted. Nothing I did worked. This natural spray works like magic and I feel I won the lottery having found it after a long battle with fleas after countless seasons of itching, rashes, and allergic reactions. All it takes is one flea to send her into an itching frenzy even long after removal. She does not come in after a walk scratching anymore and I have not been finding any fleas on her. With this spray it’s best to spray from a distance to mist your dog entirely, versus targeted spots I find and to be consistent at least once per day but honestly I have gone days without using and she is still protected but really depends on the weather and how active flea season is. I feel at ease knowing it is made with truly natural ingredients that keep my dog and family safe. Very much recommend! I hope the manufacturer does not change the formula!

For the regular 16oz version:None of the cats enjoy being sprayed, but they were far tamer with this method vs BATHING them with flea shampoo. Tested this spray on short-hair and long-haired kittens. They seemed fine. An older cat sneezed and began heavily drooling, but other than that, he seems fine.The fleas made a mad-dash to the face; even a gloved fingertip laced with the stuff was enough to deter them and cause them to slow down before they stopped moving. It took a couple of these finger swipes to get them, but some were too fast for me.I also sprayed a box a cat loved to frequent, and a hidden flea popped up right after. I should have had my phone on me to prove the effectiveness of this product while I watched it squirm around in a short circle over and over before ultimately stopping. It were a larger one, too. The spray must’ve hit that flea so hard, it didn’t know which way it were going.I were skeptical about trying this brand, due to the main ingredient being cedar-related. The first flea spray I ever tried was “Cedarcide”. All it did was slow a flea down for a bit, or lure them out towards the cats’ faces where I frantically had to comb/pluck them out bit by bit if I could catch them.Next, I tried Vet’s Best. It didn’t seem to do much, and it scared me to use it in the home and on the cats due to the peppermint, but they turned out perfectly okay. But there were still fleas and they were multiplying fast.I kept cleaning/spraying around the house with different anti-flea brands, washing fabrics and grooming the cats, feeding them flea preventative chews and giving them baths; nothing seemed to work, my arms were getting mega scratched up by multiple unhappy wet and soapy cats, and I was about to give up. I were skeptical to try Wondercide’s cedar spray due to, now, knowing cedar oil only repelled fleas and did not get rid of them. But, now I’m surprised.The cats knew it were helping them, but they still did not enjoy it. For one of the long-hairs, the best example this stuff were actually doing something was whenever I would comb that kitty after a spraying/bath, massive globs of flea dirt and rapidly moving fleas would immediately catch my eye. This time, the usual mass of flea dirt were lifted away, but NONE of the fleas were moving. That was great enough proof for me!And when I sprayed flat surfaces that appeared to have, what I guess, were teeny tiny flea eggs, they practically exploded—as in, most of them were there one second then gone the next as if they just dissolved away. A few still remained, but overall, things seem A LOT BETTER after emptying more than half the bottle along the environment and on multiple cats. The aftermath left them with sticky/clammy-feeling fur though.There have been a grand total of about 2 scratches had from 2 different cats at fleas I might have missed, as of yet. It’s still too soon for me to cast a final definitive verdict, but so far so good. I wish I had tons more of this stuff, now!!!Update: Two days later, after the extra strong aroma calmed down, some fleas reappeared seemingly out of thin air, again!🤣 Thankfully, nowhere near the usual amount. And no more flea eggs have fallen, in plain sight, so far.—Review for the larger version:Despite the pricey cost, so far, this still has been the only topical treatment that seems to actually help!As I’d originally bought the regular smaller size, after spraying the majority of two stories, the stuff was already less than half by the time I got to the cats. With this larger bottle, there was plenty left over afterward! I were able to not only spray the cats, but to do so for two different days. It were wild watching some of the fleas fall right off.Overall, this Wondercide brand is a bit hit or miss? But is still mostly effective. After spraying, once again, the cats tended to not scratch for a stretch of hours—then once they do, upon inspection, new fleas seemed to have spawned out of the ether. Even when the cat had remained in roughly the same spot or area—magically, a sudden fresh batch appears. At least, the size of this new horde is, again, typically far more meager, in comparison—but it still causes me to frown deeper than M. Bison, and think a thundering: ‘H O W ?!!!!???!!! WHERE ARE THEY COMING FROM?!!?’ Haha.As previously mentioned , the cats absolutely detest being sprayed, but they recognize that this stuff must do more good than not for them, as they readily accept what is to occur next when they see me pick up the bottle—compared to how much they’d try to scratch my head off, while I’m holding them, if they so much as glance at a tub or sink of water. So, I’d call that a win.It’s great seeing them able to nap or play, and not need to scratch for a while—but once that hind leg eventually goes up, sometime later in the day, that disheartens me and has me wonder if maybe there is some temporary itch-numbing occurring as opposed to a full-on specific flea clear out by the ingredients.I’ve no idea, but this stuff is the closest we’ve been to a flea-triumphant victory, so far. I’m not happy about that $30+ price tag, but it is lasting longer than the regular size—for me, anyway. It’s also genius marketing: have the biggest size cost an outrageous $100+, the smaller $20+, and the middle-sized one that is actually set up to be THE preferred purchase choice, is only ten bucks more? That makes the middle one the star decision, IMO. Welp, it worked! Haha.Oh, and this time, flea eggs have fallen across surfaces again.

The sand flea saga continues.... We have 3 cats and 1 dog. We think the fleas came from a trip to the beach. We started noticing signs of them on our dog about a month after we got back. By then all the pets had them. Wondercide killed a lot of them on all the pets and dosen't smell bad. It was definitely uncomfortable for them tho. They hated it, but it was much better than scratching. The scratching stopped right away. We're still trying to get rid of them 100% but this is a valuable tool. However... unfortunately it turns out one of my cats is allergic to this stuff. It seems like she licked it off herself grooming as usual but her gums turned dark brown and became swollen & inflamed. Now she wont eat anything. I'm still dealing with all this so well see how it plays out. Taking her to the vet asap. I like this product its risky to use if this is a possibility for your cat.

Do yourself a favor and just get the lemongrass. I did not like the cedarwood smell AT ALL. It’s not too strong, so that’s good, but it smells terrible. Since no one at home likes it, I purchased the rosemary. Unfortunately, cedarwood is the main ingredient in the Rosemary one. Everyone at home agreed those 2 products smell similar. I used it a couple of times and did notice a difference with the fleas.Since I still have a flea problem after cat-sitting for a week, I decided to purchase the lemongrass scent—and IT SMELLS GREAT!! It’s strong at first, but it dissipates quickly, and IT WORKS!! This stuff really works, but you have to be diligent with it. At first, I was sure the people leaving long reviews here were paid actors, but it turns out they weren’t, it actually works! The only thing I don’t like is that it’s hard to wash off your hands, I washed them 3 times and had a cookie at some point after and it had an aftertaste.
