A honey bee colony will have many thousands of members. Many will die of old age every day. If they die inside the hive, the other workers will carry out and discard their corpses. This is normal, and prevents dead bees from contaminating the nest as they decompose.
A few bees is nothing to be concerned about. If you begin to see hundreds of dead bees piling up, then they may have a problem. It could be a disease, or more likely, they may have been exposed to a pesticide.
You should seek out a local beekeeper to advise you on removing the bees from your structure.
