The Seresto settlement payout is $13 per collar purchased, $25 or full out-of-pocket vet costs for a pet injury, and $300 plus documented expenses for a pet death, drawn from a $15 million fund that Elanco Animal Health and Bayer Healthcare agreed to pay to resolve claims that Seresto flea and tick collars harmed pets. The court gave final approval on January 3, 2025, and payments began reaching claimants in late May 2025. Some claimants are still waiting.
How Much Each Claim Pays
What you receive depends on the type of claim you filed and whether you had proof of purchase.
- Collar purchases with proof of purchase: $13 per collar, with no cap on the number of collars claimed.
- Collar purchases without proof of purchase: $13 per collar, capped at two collars per pet, for a maximum of $26 per pet.
- Pet injuries: $25 for economic losses, or 100% reimbursement of documented, unreimbursed out-of-pocket veterinary costs.
- Pet deaths: $300 per pet, plus 100% reimbursement for documented medical treatment, burial, cremation, or disposal expenses.
Injury and death claims required a signed declaration along with supporting documentation such as veterinary records and financial statements. Elanco and Bayer did not admit wrongdoing, and filing a claim released the right to sue them separately over Seresto products.
When Payments Went Out
Distribution was scheduled for early May 2025. Claimant reports show payments actually began arriving in late May, sent through Venmo, PayPal, and Zelle. One confirmed Venmo payment landed on May 28, 2025.
Payment has not been universal. As of mid-2026, some claimants still report that money never arrived. When those claimants have contacted the administrator, they’ve been told their cases were being “escalated for further review.”
What to Do If Your Payment Is Missing
The claims administrator is Angeion Group. If you filed a valid claim and haven’t received payment, you can reach the administrator through any of the following:
- Phone: 1-866-790-4447
- Email: Info@FleaAndTickCollarSettlement.com
- Mail: Seresto Settlement Claims Administrator, 1650 Arch Street, Suite 2210, Philadelphia, PA 19103
- Website: FleaAndTickCollarSettlement.com
When you make contact, have the details of your claim ready, including the payment method you selected and the email or phone number tied to your electronic payment account. Payments issued through Venmo, PayPal, or Zelle depend on the contact information on file matching an active account.
Can You Still File a Claim?
No. The claim deadline was July 23, 2024, and no new claims can be submitted. The settlement covered U.S. consumers who purchased any Seresto product for personal use on or before July 8, 2024. If you missed the deadline, the settlement does not offer a late-filing route, and filing a claim would have been the only way to receive money from the fund.
Because filers gave up the right to sue Elanco and Bayer over Seresto products, that release applies only to class members who submitted claims. Consumers outside the settlement should consult a lawyer about their own options; this article doesn’t cover them.
What the Case Was About
The consolidated litigation, In re: Seresto Flea and Tick Collar Marketing, Sales Practices and Products Liability Litigation (MDL No. 3009, Case No. 1:21-cv-04447), was heard by Judge John Robert Blakey in the U.S. District Court for the Northern District of Illinois. Plaintiffs alleged Elanco and Bayer marketed Seresto collars as safe while concealing evidence that the active ingredients could cause serious harm to pets.
Seresto collars contain two pesticides: imidacloprid, a neonicotinoid, and flumethrin, a nervous system disruptor. Plaintiffs argued these chemicals were linked to seizures, paralysis, lethargy, skin lesions, tumors, and death, and that the interaction between the two could amplify harmful effects. Named plaintiff Faye Hemsley of Pennsylvania said her 13-year-old terrier mix died five days after a clean veterinary check-up, shortly after a Seresto collar was applied. Named plaintiff Aitana Vargas of Los Angeles said her Siberian Husky developed a cancerous tumor at the collar site that required emergency surgery.
The scale of reported problems was unusual. According to the EPA’s Office of Inspector General, Seresto collars have been the subject of more than 105,000 incident reports, more than any other EPA-regulated product in history, including over 3,000 pet deaths and nearly 900 human pesticide incidents. The legal claims were brought under consumer protection statutes in multiple states, including California’s Unfair Competition Law, the California Consumers Legal Remedies Act, and Pennsylvania’s Unfair Trade Practices and Consumer Protection Law. The core theory was that the manufacturers misrepresented the product “through affirmative statements, half-truths, and omissions” about its safety.
How the Settlement Was Approved
A tentative agreement on monetary terms was reached on December 21, 2023. The court granted preliminary approval on January 25, 2024, and set an objection and opt-out deadline of July 22, 2024. Only 15 class members opted out. No timely objections were filed. A single late objection in September 2024 raised a notice concern but didn’t challenge the substance of the deal. Notice went to the U.S. Attorney General and all 50 state attorneys general in December 2023 as required by federal law; none objected.
Judge Blakey granted final approval on January 3, 2025. No appeal of the settlement itself was filed, which is why distribution could begin a few months later.
The settlement agreement capped attorney fees at 38% of the $15 million fund. Court-appointed class counsel — Williams Dirks Dameron LLC, Reese LLP, and Milberg Coleman Bryson Phillips Grossman PLLC — requested just over $4.5 million in fees and roughly $150,000 in litigation expenses. Fees and expenses come out of the $15 million fund, so they reduce what is available for class payments, but individual payout amounts were set by the settlement terms above and do not shrink pro rata after the fact.
If You’re Still Waiting
If your claim was filed on time and you haven’t received a payment, the first step is contacting Angeion Group directly using the phone, email, or mailing address listed above, and asking for the status of your specific claim. Keep a record of when you called or wrote and what you were told. Claimants who’ve had payments held up have been told their cases were escalated for further review, so a documented paper trail helps if you need to follow up again.
