So, I've had some controversy on my last post about insects on your houseplants. First, the use of imidicloprid was brought into question. Of course, I am not telling you to run out and buy an insecticide and use it on every plant you have to kill everything in sight and out of sight. I always try the least toxic solution first. This includes using soap and alcohol, or neem oil in the form of Rose Rx. Now, if that doesn't work, I will use a houseplant insecticide. Some of my plants are over 30 years old and belonged to my great-grandma. I am not going to lose those plants to scale or mealybug. I have also listed the biological controls that one could choose to use in their home. Whereas this may seem contradictory to some, these bugs are the good guys. They destroy the bad guys and the plus is that you don't have to use insecticides in your home. After those good bugs have eradicated the bad bugs, they won't take over your home. In fact, without something to eat, they will probably die.

Refreshing their soil, or re-potting them on a regular basis is also beneficial. The growing media your plant is growing in can break down and disintegrate over time. Giving them new soil can be like fertilizing the plant. It gives them renewed vigor and strength.
Another way to ensure your houseplant stays happy and healthy is to place your plant in the right light for the plant you are growing. A high light plant growing in low light is a stressed plant. And just as stressful is a low light plant growing in high light.
And lastly, air circulation is a plus. I have a ceiling fan running 24/7 in my greenhouse and in my African violet room. Pests do not like wind and by running a fan, the stems of your plants are strengthened. This also helps prevent diseases such as powdery mildew and fungal diseases that can result from wet leaves.
Just remember, healthy plants are pest and disease resistant plants. Try to nip those problems and pests in the bud before they negatively affect your plants.
