Jennifer Berry for the UGA bee lab and who writes an article in every Bee Culture says that putting grease patties in the hives means you will definitely invite SHB. SHB won't be a problem , as others have mentioned, in a strong hive - the bees keep them under control. As with wax moth, if you find damage in your hive from the SHB, then it means your hive is weak - not that the beetles are strong.
