Aphid Infestation

Aphids are small, soft-bodied insects that pierce the leaf tissue of Cattleya orchids to suck out sap. They excrete a sugary substance known as 'honeydew,' which creates the characteristic sticky residue on the leaves.

Very Common

How to confirm: Inspect the undersides of leaves and new growth for tiny, green or black moving insects.

Scale Insect Infestation

Scale insects attach themselves to the stems or leaf bases of Cattleya orchids and feed on plant fluids. Like aphids, they excrete honeydew that coats the leaves in a sticky film.

Very Common

How to confirm: Look for small, stationary, bump-like protrusions on the canes or leaf undersides that can be scraped off with a fingernail.

Mealybug Infestation

Mealybugs secrete honeydew while feeding on the orchid's nutrients. While they are often covered in white, cottony wax, the residue left behind on the leaves is very sticky.

Common

How to confirm: Search for small, white, fluffy clusters tucked into the leaf axils or where the leaves meet the pseudobulbs.

2 Gently wipe the sticky residue and any visible white cottony masses off the leaves using a soft cloth dipped in isopropyl alcohol or insecticidal soap.
3 Improve air circulation around the orchid to prevent further honeydew buildup and discourage pest colonization.
warning

Soft Scale or Coccus species

Certain types of coccid insects are less visible to the naked eye but cause significant honeydew production, leading to a shiny, sticky appearance on Cattleya foliage.

Common

How to confirm: Wipe the sticky area with a white cotton swab to see if any minute, translucent organisms are present.
