Monstera Costaricensis pests — FAQ
What is eating my monstera costaricensis?
Monstera costaricensis, a large Central American climbing aroid, is prone to the same indoor pests as other Monstera species. Spider mites are the principal threat in low-humidity interiors. Mealybugs colonise the thick petioles and leaf axils, while scale can establish on mature stems. Fungus gnats thrive if the chunky substrate stays too wet.
