Are they flea larvae? The digs have fleas at the moment, which seem totally resistant to everything; we have tried spot on, flea collars and flea shampoo, but it seems to make no difference. I am going to ring the vet tomorrow to see what else they have got, but was just checking that the 'worms' were flea larvae??? Or something else,equally as disgusting!!!
The only time I've ever seen flea larvae is when I rescued a feral kitten at my grandparents' house in Ireland as a child. I had to carry it home clutched to my front as it was injured, but wild and when I put it down my jumper was covered in little crawly maggots. <-- not envy The kitten was riddled with fleas, so I assume they were flea larvae. I totally freaked out and burned my jumper!
Definitely get to the vets and get some Advocate for the dogs, then treat your whole house with something like Acclaim, Indorex or Nuvan Staykill. The vets should be able to give you both.
