Yes, They are correct. You'll need to get some deworming medication from the vet, likely Panacur. As Lija noted, all frogs in the enclosure will need treated, or they will keep infecting one another.

Remove the substrate and wipe down the floor. Use paper towels as flooring/substrate and change daily. Be sure to dechlorinate your water too. Be sure to change the water bowl water every day.

Most worms can be treated within 4 weeks with a weekly Panacur treatment. Most vets will want a stool/feces specimen. Get a fresh poo and place it in a new baggie for the vet to test.

Dewormer is the only way to rid of worms. Unfortunately they will not go away by themselves. If your local vet cannot help, (I'd call them first to check), then there is a vet in Michigan that likely will. Please let me know. If you need his contact number I will give it to you.

Good luck and please keep us updated.
