How do y’all grow your catasetums successfully?

I can grow any other orchid species, but with catasetums I have only had trouble and pests.

For some reason I keep getting every pest immaginable on them. Even when growing sparately or in a closed off space. When I do manage to chase the pests off successfully, the treatment stunts the growth of the pseudobulb, thus making flowers impossible.

Its simply a headache at the moment. How do you do it??
