You might be feeding it too much. The soft, leggy growth that overfertilization causes is very attractive to bugs. Try cutting it back to encourage new growth. Only feed it monthly spring to fall. Also, are you giving it a dark rest period in fall? It needs that to set buds. During that time cut back on watering, don’t fertilize at all, and make sure the plant gets 14 hours of darkness. Also, in your hot climate it might be difficult to keep the plant cool enough during the rest period. Getting your Kalanchoe to rebloom can be challenging but it will be worth the effort.
