Frequently Asked Questions

About CycleKiller

Here are some additional tips and tricks for getting rid of fleas for good on your pets and in your home.

Are fleas (and flea eggs) that big of a deal?

Cat fleas and dog fleas are some of the biggest threats to your pet's health. When fleas bite people and animals they can cause skin irritation, infection, and several diseases. Other animals carry fleas, but the dog and cat flea species are the most common.

The flea life stages include:

  • Flea eggs

  • Flea pupae

  • Flea larvae

  • Adult fleas

Your best protection against fleas and overall disease control is by avoiding them altogether. Get rid of fleas right away with vet-quality flea and tick protection.

How do pets get fleas or flea infestations?

Most dogs and cats catch fleas from another infested animal. Think dog bars and parks, boarding kennels, and wild animals in backyards or parks. Fleas can jump several inches in the air and easily make their way from one pet to the next.

Once an adult female flea feeds on your pet it will lay eggs. Dozens of immature fleas fall on your pet and your pet's bedding. Then, eggs begin hatching and start the life cycle over again.

How do I get rid of fleas in my house fast?

Here are three important steps to take to get rid of fleas in your home fast:

  • Treat your pet with Nitenpyram or a topical treatment

  • Vacuum everywhere (carpet, floors, furniture, your pet's belongings)

  • Apply a household flea and tick spray around your home

After you've completed these steps, examine your pet for flea bites and adult fleas using a flea comb. If you are still seeing fleas, consult your vet for advice.

How often can I treat my pet for fleas?

Every flea issue is unique. It depends on the size of the flea population and what steps you've already taken to eradicate fleas. Oftentimes, flea and tick treatment alone isn't enough to put an end to a flea infestation.

Some products are safe to use once a week for one month to frontload your protection. But, most brands recommend monthly use for best results. Consult with your vet before treating your pet with a new product.

What gets rid of fleas ASAP?

CycleKiller is the quickest way to get rid of fleas. The first step is an oral treatment that contains the active ingredient Nitenpyram — an insecticide that you give your pet orally. It begins working within 30 minutes to kill 90% of fleas.

We provide 2 doses of Nitenpyram per pet. Follow the instructions below to ensure each cat and dog in your household gets the right treatment.

Can I use Dawn dish soap?

Our CycleKiller kit includes degreasing soap for your pets. This helps remove dead or dying fleas from your pet's fur after you've treated them with Nitenpyram. Be sure to wait at least 24 hours before applying topical treatment after bathing your pets in degreasing soap.

Dawn dish soap or flea shampoo can be used to kill adult fleas. But, it shouldn't be used as a long-term solution. This is because it will only kill adult fleas on your pet. Dawn won't repel fleas living in and around your home from reinhabiting your pet's fur.

I'm seeing more fleas, is that normal?

Yes, it's normal for them to rise to the top of your pet's fur as fleas die. So, consider it a win if you start seeing more fleas after you apply the treatment.

If you’re still seeing fleas, it may be because your pet has picked up new fleas from their environment. This can include other animals, surfaces, and outdoor areas.

What tools do I need to treat fleas?

Controlling fleas involves many steps and important timing. We include the most important items to help kill fleas on your pet and in your home including:

  • Nitenpyram oral treamtent

  • Topical flea prevention

  • Household flea spray with an IGR to kill fleas

  • A flea comb

  • Degreasing soap

  • Treats

Some other items to help you on your road to flea freedom include:

  • A spray bottle of hot water to check for flea dirt

  • A vacuum cleaner

  • Baking soda mixture to clean surfaces

Where should I eradicate fleas in my home?

A flea infestation doesn't just affect your pet. Besides treating your pets for cat and dog fleas, you must also treat your home. This will ensure you pick up any remaining eggs that might've dropped from your pet.

  • Vacuum furniture, floors, and rugs

  • Throw the contents of the vacuum bag in an outdoor trash immediately

  • Wash sheets and blankets in hot, soapy water

  • Clean your pet’s belongings

  • Apply a light mist of household spray to other areas where your pets spend time (on pet bedding, pillows, blankets, furniture, and baseboards)

  • Use household spray every 14 days to kill any new fleas

Can adult fleas live on bedding?

Yes, fleas can live between the cracks in your hardwood floors, baseboards, and corners of upholstered furniture. But, they are pretty easy to avoid if you wash bedding with soapy, hot water regularly.

What should I look for in a household spray?

Besides using a topical treatment, you should also use a flea and tick spray in and around your home. This is because the female flea will lay eggs that can drop throughout your home.

Our flea spray contains an Insect Growth Regulator (IGR) that can be used on your house. IGRs help break up flea habitats to prevent further breeding and severe infestations.

After you've cleaned your home and completed every step to treat your pets, spray these key areas with Household Spray:

  • Throw rugs and carpets

  • Hardwood floors

  • Baseboards and trim

  • Couches, chairs, and ottomans

  • Pet beds, blankets, and toys

Wait for the spray to dry completely after a few hours before reentering the area with your pets. You can also allow it to sit overnight.

Will fleas present in the house go away on their own?

Typically not if you don't take preventative measures. The general rule of thumb for flea prevention is:

  • Quarterly: Safeguard your home with household spray

  • Monthly: Protect your pets with a topical flea & tick treatment

  • Weekly: Vacuum carpets and wash bedding and blankets in hot, soapy water

*Pro Tip: Hire a pest control professional to treat your home and yard regularly.

How does this work for each species?

For dogs

Give 1st oral treatment

Nitenpyram is the best way to kill adult fleas (90% effectiveness within 4-6 hours). It should start working within 30 minutes. Ensure your dog consumes the entire pill. You can break it over food or coat it in peanut butter. Repeat the 2nd treatment after 24 hours.

Remove dead fleas

Removing dead and dying fleas can prevent them from coming back. Use the flea comb to remove fleas and rinse the comb in warm, soapy water between strokes.

Bathe your pet

Clean pets are happy pets. Use the degreasing soap in a warm bath to suffocate the remaining fleas and remove flea eggs or flea dirt stuck in their fur.

Apply Wags Advance® for Dogs

Part your dog’s hair at their neck. Touch the applicator tip to their skin. Gently squeeze the tube in 3-4 spots along their spine, ending at the base of their tail. Wags Advance® can be applied once a week for one month.

For cats

Give 1st oral treatment

Nitenpyram is the best way to kill adult fleas (90% effectiveness within 4-6 hours). It should start working within 30 minutes. Ensure your cat consumes the entire pill. You can break it over food or coat it in tuna. Repeat the 2nd treatment after 24 hours.

Remove dead fleas

Removing dead and dying fleas can prevent them from coming back. Use the flea comb to remove fleas and rinse the comb in warm, soapy water between strokes.

Apply Purrs Advance® for Cats

Part your cat’s hair at their neck. Touch the applicator tip to their skin. Gently squeeze out the entire tube. Purrs Advance® can only be applied once a month.

What is the happiness guarantee?

As a pet owner, dealing with flea problems can be scary. Fleas, ticks, and other pests can cause allergic reactions and other serious problems for your pets.

This is our promise to you that we'll do everything we can to ensure your household is rid of fleas (or your money back). You can read the full details of our guarantee here, but there are a few steps you can take to ensure you eliminate fleas for good:

  • Apply flea treatment to every animal in your home (if you have other rodents or a feral cat nearby, we will not be able to offer a refund).

  • Continue monthly prevention to avoid future problems. While CycleKiller effectively eradicates fleas on pets and within the home, at the time of use, it does not prevent future flea infestations.

  • Follow each step and the timing associated as closely as possible. It can take several weeks to eradicate fleas. Our veterinarian team is here for you every step of the way!
