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.
