What scale does

Scale insects attack trunks and limbs, drawing sap and causing branch dieback when infestations are not controlled.

At Park City elevation, stress factors such as drought, compacted soil, warm winters, heavy snow years, and poor irrigation can make trees more vulnerable. Treatment works best when the pest is identified early and the timing is right.

Symptoms to watch for

  • Sticky residue, bumps on twigs or needles, discoloration, thinning, or premature drop
  • Browning needles or branch dieback
  • Small holes, pitch tubes, sticky residue, or trunk damage
  • Declining vigor after hot, dry weather or hard winters

Greenleaf treatment approach

Systemic soil injections or topical sprays based on crawling stage. We inspect the tree, confirm the pest or stress factor, then recommend the least excessive treatment that can realistically help.
