There are quite a few different insects & pests that can infect any plant that grow indoors. When the symptoms of these infestations become known you should take immediate remedial action because failure to do so will allow the infestation to spread to the other plants and lead to complete destruction within just a short period of time.
The most common plant pest is the spider mites. These are a very serious problem for plants as they multiply very fast, lead to defoliate and kill the plant.
These mites belong to the family of ticks and spiders. Spider mites are yellow or green in color and cannot be seen easily. To check for presence of spider mites tap the leaf over a piece of white paper and check for very tiny movements on the paper. Remove them with an insecticide spray from your plant store.
Shell Insects appear like a small bump of wax on a stem or leaf. It is usually not possible to view these creatures without magnification, but when their numbers increase they make their presence known.
Shell insects stunt a plants growth and can even kill the plant in time. The only known solution is an insecticide spray.
Mealy Bugs are easily visible without having to magnify the pest. These insects look like they have come out of a sack of flour and have a long waxy protrusion from their tails.
These appear like small clusters of cotton on the plant. Check the under side of the leaves to notice these pests and when you do find them wash them off with water and spray with insecticide for plants.A couple of weeks of treatment and you will be rid of these pests.
Pests not only kill a plant in time, they are also very unsightly. A beautiful plant will become ugly and the whole purpose of decorating the place is defeated by plant pests.
Proper cleaning and regular spraying with insecticide will help prevent any kind of pest infection.
