  • Nurseries or Garden Centers

There’s a clear incentive for spider mites to target nurseries.

The abundance of plants makes garden centers attractive to these pests. Because a lot of plant lovers visit such nurseries, it’s easy to bring in spider mites that may have been picked from plants close by or from your garden.

As you purchase spider mite-infested plants from the nursery, you unknowingly bring them into your garden. This results in further spread across all plants within the garden. Of course, the result is the destruction of such plants when left attended.

  • Large Plants

Large plants tend to be more attractive to spider mites due to their rich foliage which provides ample food supply to these pests.

When there are large untreated plants around your home or garden, it’s certain to result in the spread of spider mites to other smaller and larger plants alike.

With more foliage comes an increase in spider mite population and activity. As always, action is necessary to eliminate these pests from your property. More about treatment will be discussed shortly.

  • Excess Nitrogen Application

Plants require nitrogen to develop properly. However, when too much of it gets applied, it serves to attract pests such as spider mites. Excess nitrogen leads to funny proteins being produced.

This in turn results in spider mites sucking their juices.

  • Pets

By their nature, pets love to roam around the yard and neighborhood.

Also, they wouldn’t hesitate to take a rest among plants. All such actions result in spider mites clinging onto pet fur. Unknowingly, the pet transfers these pests to other plants.

The most common, yet effective method is by spraying or hosing your plants. More focus should be underneath leaves. Neem oil can be used too.
