Getting rid of pests that frequent Hoya Kerrii is relatively easy. If you can’t catch them by hand, be sure to use a spray bottle with water, or even invest in an insecticidal blend of soap. Make sure to invest in a blend that’s cruelty-free and kind to the environment. You normally won’t see many pests around your Hoya Kerrii unless you open your windows frequently. Typically, these plants fall prey to the likes of aphids, which prove to be some of the biggest headaches for indoor and outdoor gardeners alike!
