If the hotel has a bug problem, it’s the hotel’s problem, not the animal. You wouldn’t blame the hotel for a dirty customer leaving behind bedbugs, but you would blame them for not getting rid of the bugs. I’m generally worried about the sanitation in hotels, but not specifically if they allow pets. In fact, I’ve stayed in hotels with my dog, and in pet-friendly hotels without a pet, and they’ve been as clean or cleaner then standard hotels. Since dogs leave behind hair and dirt, I think most decent pet friendly hotels are more aware of the cleanliness issue.
