About Wondercide Flea & Tick Spray

Kills Fleas and Ticks

Wondercide’s family-safe, plant powered sprays for dogs and cats help kill fleas and ticks and stop their lifecycle (eggs, larval/nymph, pupa, adult) within hours rather than days. Their Flea & Tick Spray for Pets + Home works externally and without toxic ingredients, so you can use it worry-free on your pets and throughout your home.

Four Great-Smelling Scents

Wondercide Flea & Tick Spray comes in fresh, aromatherapeutic scents powered by natural essential oils. Try calming and comforting cedarwood, relaxing and restoring rosemary, revitalizing and invigorating lemongrass, or uplift and refresh your senses with the peppermint scented spray. They are all equally effective against fleas and ticks, so choose your favorite!

So Easy to Use

Rub your pet’s coat in the opposite direction of growth and spray a light but thorough misting over the body, belly, legs and tail. You can spray it into your hands to apply to your best friend’s ears and face. Then, just rub it in all over and you are done! Use daily for an active issue or 2-3 times a week to help prevent pesky pests. Spray your pet any time fleas and ticks might be a threat.

360° Protection From Bugs

Get complete flea and tick protection on all fronts by using Wondercide products on your pet, in your home and in the yard. Protect your yard with Flea & Tick Yard + Garden spray, then spray your furry friends and home with Flea & Tick Pets + Home. Wondercide sprays are powered by pure, natural essential oils and come in both ready-to-use and concentrated refill formulas.

About Wondercide

Wondercide was founded by a concerned pet parent whose fierce love for her sick dog, Luna, led to a new approach to flea and tick control. The goal was to protect pets, families and homes with non-harsh formulas and provide an alternative to the usual remedies. Today, Wondercide helps protect packs of every kind, everywhere, with thoughtful, plant-based products made with love.

Questions & Answers

8 Customer Questions

Is this safe to use on a bed that humans sleep on?

Answer by Chewy • Jun 09, 2021
This spray is safe for use on carpet, furniture, bedding, flooring, cat condos and in dog kennels. This formulation uses natural, safe, human food-grade essential oils as the active ingredients, so you can confidently use on yourself as well as your pets. Peppermint oil has been known to affect milk production in nursing mothers.

Can you use this in addition to oral flea and tick medicine? Such as Nexguard

Answer by Chewy • May 17, 2021
Full-strength preventatives are intended to be used alone. We encourage speaking with your vet before combining pest preventatives for the safest opinion.

How many months is the product good for? How many months until the expiration date?

Answer by Chewy • Apr 14, 2021
When stored properly, this spray is best used within one year of purchase. Optimal storage conditions for all products are cool, dry places out of direct sunlight. To determine if your product is still within the best-by date, find the production date on the bottom of the bottle.

Is this product safe to spray on my own skin and hair?

Answer by Chewy • Nov 04, 2022
The formulation is made with natural essential oils, so you can confidently use on yourself as well as your pets. Applying this product to skin or clothes will not kill pests. You have to spray pests directly to kill them. It will repel on people and pets. On people, re-apply every hour or as needed.

Toxic, unnatural, too strong

I ordered Rosemary scented, as I knew the cedar wood scent would be absolutely way too strong, almost pungent. I was very disappointed but not surprised, rosemary is just as strong, gives a terrible headache, loose spray nozzle that drips oil everywhere, my pup hates it and gags when he sniffs it. Not sure how it helps with the flea situation but smell wise, immediately I am nauseous, and uncomfortable after smelling this. It also contains SLS which I should’ve read further into. Overall if you like strong smells and endocrine disruptions, this is great.

I previously gave this product a premature mediocre review. I have 3 cats & the fleas are crazy this year. I have applied it for the past week & the scratching has all but stopped. The scent is initially strong but mellows after a bit. I use it on my couch & bedding too. Just wait for it to dry & you can hardly smell it. Although the smell sticks with my kitties. Again, initially strong but it is effective & offered in various scents. I will continue to purchase this amazing product.

The nozzle is useless, it sticks down after one spray and comes apart when you pull it up. If we didn’t have a spare handy from a different product, then this bottle

The nozzle is useless, it sticks down after one spray and comes apart when you pull it up. If we didn’t have a spare handy from a different product, then this bottle of Wondercide would be completely useless. There is a strong smell that permeates an area so use outside or in a well-ventilated room, and it doesn’t fully deter fleas (we still find one or two after every walk). Low-key I hate it

I have been using Wondercide products since the company started. I use the indoor products, flea and tick, and yard spray. I started using the product after 2 of my small dogs had reactions to Frontline. I had 7 small dogs and 2 large dogs. All do well with this product. My yard is treated 2x a month and my dogs once a week once Spring arrives. I don’t use it as much after we get a good freeze. I also have used multiple scents. Oh and I even used it on myself when I was going to be outdoors one evening for a get together. No mosquito bites - that was impressive as I always get bites. Highly recommend you give it a try.

The ticks have been everywhere this summer but this spray is very effective at repelling and killing the few that did latch onto my dog's legs. This is my second bottle and the scent is very pleasant. I will continue to purchase and use this spray.

I was disappointed. I wanted to use something with natural ingredients. This did not kill any fleas. I even tried the Wondercide Shampoo same results. I would use the flea comb afterwards, and fleas were present.

I have 2 dogs and I like to spray them with this nontoxic bug spray before a walk. The sprayer top gets stuck after one pump. It won't pop back up even if I press again and again. It makes it not useful for me because I can't get the product on both dogs.

I know ppl swear by it and I hoped to use instead of chemicals for flea/ tick for my 3yr old mixed lady,I sprayed on as directed within minutes she started coughing, the sound made like trachea collapse cough,I waited a bit,it continued so I hurried to bathe her and it stopped, so maybe a great product, just didn't work for me

How fast it kills the fleas

Moving to a new home has brought new issues to the table my babies and I have never dealt with. I wanted a nontoxic alternative to generic flea and tick treatments

Moving to a new home has brought new issues to the table my babies and I have never dealt with. I wanted a nontoxic alternative to generic flea and tick treatments so I gave this brand a go and so far it's been doing wonders. I don't care for the smell much and my cat mochi doesn't like it at all but aside from that it's been a great product very efficient.
