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

18 Customer Questions

Does this spray expire?

Answer by Chewy • Jun 09, 2021
Flea & Tick Spray for Pets + Home are best when used within one year from the date of purchase. Proper storage is key for maximum shelf life. We recommend storing in a cool, dry place out of direct sunlight.

Has this spray caused any discoloration/ damage to any fabrics

Answer by Chewy • Aug 28, 2022
Lemongrass oil has a naturally yellow tint and may temporarily discolor light fur and fabrics. It will wash out of fur. If you have a pet with a light coat or you plan to spray light-colored household surfaces, consider another scent or test fur and surfaces before use.

How long does it take to kill the fleas on pets and in the home?

Answer by Chewy • Nov 03, 2022
This spray kills by contact and works quickly. Wondercide has testing to support that in a lab setting, their spray kills 99% of fleas within 2 minutes and 100% shortly thereafter. It is important to treat the yard during an active infestation to get rid of fleas at the source and break the lifecycle, while also treating pets daily until you no longer see live fleas, treating the home fully once or twice, then spot treat.

What if my dog/cat licks this after applying?

Answer by Chewy • Apr 02, 2021
Because Wondercide products are made from safe, naturally-derived ingredients, it's okay if some is consumed or licked off. As with most things, overconsumption may lead to an upset stomach, but is otherwise fine if some is licked after spraying. Limit excessive licking to ensure the spray stays on your pet and remains effective.

A natural flea killer that actually works!!

I got the spot doses, the spray & the shampoo. I haven’t seen fleas since I started using these & I plan on getting the yard spray as soon as it gets above freezing

I got the spot doses, the spray & the shampoo. I haven’t seen fleas since I started using these & I plan on getting the yard spray as soon as it gets above freezing here in Missouri consistently.

Strong very strong

The lemon grass one is super strong it irritated my dogs eyes, their eyes were watery and they kept sneezing. We sat outside for an hour before entering the room

The lemon grass one is super strong it irritated my dogs eyes, their eyes were watery and they kept sneezing. We sat outside for an hour before entering the room but the smell is super strong even the candles cant break the smell. As far as fleas im not sure if it works I know next time I spray it I will definitely be sitting outside longer than an hour. Had to open the windows and plug fans in.

Waste of money

Spray throughout my home and around door ways both in & outdoor. Did nothing to minimize the flea issue. Even spraying on my dogs backside it didn’t work

Although my dog takes an oral medication for fleas and ticks, that doesn’t stop them from jumping onto him when we walk through the woods and then I have to deal

Although my dog takes an oral medication for fleas and ticks, that doesn’t stop them from jumping onto him when we walk through the woods and then I have to deal with them at home. But this product really keeps them away during our walks in the woods because of the smell! I just spray him before our walk and we’re good to go!

Lovely smelling!

Seems to do a wonderful job keeping ticks and gnats away from my large greyhound. Even on Nexguard, I wanted something to deter ticks as we have heavily wooded areas

Seems to do a wonderful job keeping ticks and gnats away from my large greyhound. Even on Nexguard, I wanted something to deter ticks as we have heavily wooded areas. This has been great. I especially enjoy the fact little gnats are no longer hanging around his underside when we are outside in the summer. The lemongrass scent is my favorite and my dog doesn’t mind being sprayed with it. (I spray it on my hands to put on his head). I highly recommend!

We bought a house and quickly learned it was infested with fleas. While I used more hard core treatments in the basement, where the previous owners had their pet litter boxes, I wasn’t comfortable using them in spaces my dog uses. I am pleasantly surprised how successful we’ve been using this product consistently over the last few months. We’ve been flea free now after about 4-5 months of use. I still spray it after I vacuum just to be sure (and I like the clean smell) but am so thankful to have found something that’s safe to use around pets and so effective!

not so many bad chemicals

Tried many methods for 2 months. Finally found Wondercide and used it every other day along with diatomaceous earth. BINGO fleas gone within 2 weeks.

It smells pleasant, very strong when first applied but dissipates. My dog does not like being sprayed, so I spray it into my hands and rub it on him. I decided to discontinue oral flea-tick medication in favor of a topical repellent because the medication did not repel flying insects (my dog is on heartworm preventative but mosquitoes and gnats whining around him were still annoying). I am happy with this product. Flying bugs do not pester him (or me; I use it too!) I do a tick check after every adventure in woods, meadows, and weeds. I have found only one tick crawling on him, and none attached. So it’s not 100% (would have given 5 stars if I hadn’t found that one tick) but it’s very effective. With the oral medication, I nevertheless pulled off many attached ticks, dead, but attached. None have attached with Wondercide. I have not seen any evidence of fleas. I hike and backpack with my dog (Jack Russell Terrier) and ordered the small bottle to try it. I will be re-ordering, the larger one this time. I ordered little 1-oz spray bottles from (big online retailer, starts with A) so that I can take small amounts on backpacking trips. I recommend this product.
