Infected leaves can be easily picked off and destroyed. Spider mites are very small and are very hard to see without a magnifying glass, but heavy infestations can cover the leaves with very fine webbing quickly. The plants gradually lose their green color and appear dusty or speckled. Submerging the plant in a solution of mild soapy water is often succesful in combatinng mites. You can also use insecticidal soaps or use a house plant insect spray according to label directions.
Mealybugs look like white puffs of cotton.
They suck plant juices and heavy infestations will coat the leaves with sticky honeydew. Mealys can be tough to erradicate. They have a waxy covering which tends to repel liquids. Systemic insecticides and some house plant insecticides are sometimes effective, but be certain that it is appropriate to use them on ivies. Always read the entire label of any pesticide or other chemical, and only use when it is absolutely necessary.
