Quick Tip & Pests – Oh No….Spider Mites


I have some lavender plants on a windowsill near my desk. I love to stop what I am doing and brush them with my hands. The lovely, fresh scent of lavender fills the air and gives me a boost of energy amid mid-winter doldrums. 

You can imagine my outcry when, out of the corner of my eye, I  spotted movement on my lavender—spider mites. The tiny pests were fearless and having a marvelous time, creating webbing, feasting on the juices, and multiplying by the minute. 

Running the plant under a heavy stream of water is always my first course of action. The spider mites are small and are quickly swept away by the deluge. So far, my initial treatment is working, and I’ve only seen one or two stray mites.

One of the problems with diagnosing spider mites on a houseplant is their size. The webbing and drying leaves are a clue to an infestation. Sometimes, as in my case, you can see them moving along their webs. To be sure I was aware of all the infested spots, I sprayed the lavender with water before washing the mites away. The side-by-side photo shows how much easier it is to see an infestation after spraying.

Unfortunately, I must be realistic; removing every spider mite from the lavender will most likely take several sessions under the faucet. This pest spreads quickly in the dry air of a heated house. I will check all my houseplants for infestation with water sprays throughout the week. 

Problem-Solving – Conquering Houseplant Pests Part I – Mealybugs

At this time of year many of us are bringing houseplants indoors from their ‘vacation’ time on porches and the great outdoors. Unfortunately, when we do so, we often bring in a few hitchhikers in the form of mealy-bugs. Here’s a timely repost of a few tricks to control houseplant pests organically.

While watering my succulents I noticed the dreaded white fluff of a Mealy Bug. Oh no. I have had experience with these pests in the past and know they can become a full-blown infestation. I wasted no time in treating the infested plant.

I like to use organic products and things I already have around the house. For Organic Mealy Bug Treatment Isopropyl Rubbing Alcohol is a good choice. Using a Q-tip I touched the saturated tip to the back of the mealy bug. As I checked the plant I saw a few more of his family residing along the stems and treated them too. Further down there were more, oh no, it was beginning to look like an infestation, time for more drastic measures. I filled an atomizer with some of the alcohol and sprayed the entire plant. I left it on for a few moments and then washed all the foliage in tepid water. Most organic pest control sites recommend watering the alcohol down first, but for a hardy succulent, straight out the bottle did no harm. If I was treating one of my african violets I would definitely water the solution down before using.

I knew I had to check all the plants that were in the same room with the infested succulent, and sure enough, on one coleus I found the beginnings of more mealy bugs. Hopefully the intervention with rubbing alcohol has eradicated the problem.
