Mandevilla do best if brought indoors once the temp drops to 50 degrees or lower. To aid in treatment of pests on your plant it is recommended to trip as soon as your plant has quit flowering. Don't do any fertilizing through the winter and keep watering to mimum.
Holy cow lol! This is fate or kismet because I just found some pesty bugs on my mandevilla. I called my mother in law and she said all I had to do to treat the plant was mix some liquid dish soap with water in a spray bottle and spray!
Wellllll that works on a lot of plants and insects but spider mites are stubborn so I learned to purchase a commercial grade insect soap. They have organic types now so it will be safe for kids and pets :-) posted by

Well it really kinda depends on what kind of pest you've got. Some mandevilla will get mealy bugs. Look for a white mass. Use a Q-tip and alcohol and dab each mass. Continued treatment is to spray the plant with 50% isopropol alcohol and 50% water. Good luck!
The most common pest is spider mites, and the best treatment is prevention. Increase humidity by hosing the plants frequently. An insecticidal soap will take care of stubborn problems.
