Pine can be difficult to detect. small white spots are the draw.

Uh-oh, white spots

If it is fall or early spring in which I live, is always what I think is – pine needle scale. This is why it can be difficult to detect. When they are growing on the inner surface of a pair of pine needles, which are almost invisible.

A piece of white is the gift

Peel apart needles reveals the insect -. Small white spot with even smaller yellow dot at one end

If you have detected them in time, I will find single or couples them in a limited number of needles. If I do not do anything about it, a few days could find me more.

Yuck! – More scales of pine needles

The reason why I’m not a fan – it can be difficult to control. Many of the weaker pesticides have trouble killing scale. They usually begin with the touch sensitive approaches and increasingly powerful attacks mount as necessary. My general approach is the same as it is for any scale:

  • If there are only a few that will scrape the nail
  • If I have to spray, I’ll start with oils
  • If the oils do not get them under control, I’ll use something more toxic, although usually avoid this last step because I do not like the use of pesticides.

What is most important to know about the treatment of scale? If possible, avoid getting it in the first place. How can once occur on reducing power and the number of infestations?

  • Keep your healthy trees. This includes a lot of sun, water and appropriate fertilizers and soil with good drainage.
  • do not give them room to hide. Leaving the old leaves or needles in place prevents light and air from reaching the interior of the tree -. This is how scale as if
  • Use oils on a regular basis. oil sprays are less toxic treatment for scale.
  • If you know that there are a lot of scale in the area or have struggled in the past infestations, systemic pesticides are a good bet.
