Bermuda's Department of Environment & Natural Resources (DENR) asks for a tick treatment as one of its conditions of entry for dogs and cats.
What decides whether a product qualifies is its active ingredient, not its brand name. Manufacturers rename, reformulate and discontinue products constantly, so DENR's published list is organised by active ingredient, with brand names given as examples of products that contain them. A product your veterinarian has that is not named on the list may still qualify if it contains a listed acaricidal ingredient. Equally, a familiar brand name is not enough on its own if the formulation does not contain one.
One exception, and it is absolute. DENR also publishes a list of products it does not accept. If a product is named there, it cannot be used, whatever its ingredients. Check that list first.
Always confirm the current list with your veterinarian and on the government page before the appointment: Import a domestic dog or cat (gov.bm)
What Bermuda asks for
DENR's condition is a veterinary statement naming an acaricidal preparation known to have residual activity against a variety of ticks, which was administered or applied during the examination.
Three things sit inside that sentence, and all three are DENR's requirement:
The preparation must have residual activity against ticks. That comes from its active ingredient. Check the ingredient panel on the packaging against the list below, not the brand on the front.
Your veterinarian must give it during the pre-export examination. DENR states that dispensing a product for the client to use later is not an acceptable option.
The preparation and method of administration must be named in writing. Use the in-app PadsPass Health Certificate Generator for Bermuda and all of this will be documented correctly.
This is the requirement travellers most often get wrong, usually by using their pet's normal monthly preventative at home instead of having the veterinarian apply a qualifying product in the room.

Products DENR names as not accepted
Advantage, Advocate, Bio-Spot, Capstar, Comfortis, Credelio for Cats, NexGard Combo for Cats, Revolution, Promeris for Cats, Provecta-II for Cats, selamectin, Sentinel, Vectra, shampoos and collars.
Reading the two lists together
Most of the exclusions above make sense once you look at the ingredients rather than the names. In a combination product, it is the ingredient with tick activity that does the qualifying:
Vectra is not accepted, Vectra 3D is. Vectra 3D adds permethrin.
Revolution is not accepted, Revolution Plus for cats is. Revolution Plus adds sarolaner. Selamectin on its own appears on the not-accepted list.
Promeris for Cats is not accepted, Promeris for Dogs is.
So the working rule is: the product needs an ingredient with residual tick activity, and in a combination product that acaricidal component is what qualifies it. A wormer, a flea-only treatment or an insect growth regulator does not become acceptable by being sold alongside one.
Two cases to confirm with DENR rather than assume:
Advantage. DENR lists imidacloprid as an accepted ingredient and also names Advantage as not accepted. Advantage is imidacloprid without permethrin. Do not rely on the ingredient row to use Advantage.
Credelio for Cats. Lotilaner appears as an accepted ingredient for Credelio for Dogs, while Credelio for Cats is named as not accepted.
If either is what your veterinarian intends to use, check with DENR first on (441) 236-4201 or animals@gov.bm.
Bio-Spot needs the same check. It appears on the not-accepted list, while Biospot Spot On and Bio Spot Spot On appear as acceptable etofenprox and permethrin products.
Shampoos and collars do not count, however recently they were used, and regardless of what they contain.
Bravecto has a time limit. DENR accepts it for a maximum of 60 days, which is shorter than its usual dosing interval.
Species matters. DENR's list does not break every product down by species, and several entries are labelled for dogs only. Your veterinarian chooses a product that both qualifies and is appropriate for your dog or cat.
Timing
The treatment is given at the same visit as the health certificate examination, which Bermuda asks to be issued within 10 days before arrival. DENR states that import permits are valid for 10 days from the date of the veterinary health certificate, and that its office is closed at weekends and on public holidays. Build that into your appointment and travel dates.
Record it in PadsPass
Add the treatment to your pet's profile as a Parasite Treatment as soon as it is given, and upload the veterinary statement or health certificate that names the product. Record the active ingredient as well as the brand, since that is what the requirement turns on. Keeping it in your pet's Digital Pet Passport means the product name, the ingredient, the date and the document sit together if anyone asks for them at check-in or on arrival.
If you have not finished your pet's profile yet, start there. A complete profile (microchip number, first scan date and the two most recent rabies vaccinations) is what lets us help you with a Bermuda trip.
