Abstract
It is shown that membership in rational subsets of wreath products H≀VH≀V with H a finite group and V a virtually free group is decidable. On the other hand, it is shown that there exists a fixed finitely generated submonoid in the wreath product Z≀ZZ≀Z with an undecidable membership problem.
