Ips Engraver Beetles

KillerSeriousManageableMostly cosmetic

Small bark beetles that move into stressed, storm-damaged, lightning-struck or drought-stressed pines. Once they colonize a pine, it usually dies. With the black turpentine beetle, they are the bark beetles of South Florida.

Trees it affects: Slash pine, All Florida pines

Report a concern Request an assessment

Reddish-brown boring dust packed in the bark at the base of a pine. Our field read: Ips engraver beetles at work.

Affects: Slash pine, All Florida pines
When it shows: Year-round. Buildup can run months to years after a hurricane.
What we do first: Check the size and height of the pitch tubes, then lift a bark flap.

What you see

Signs in the field

Pitch tubes about the size of a dime, 2 cm (about 0.8 inch) or smaller, scattered along the mid and upper trunk and branches
Reddish-brown boring dust in bark crevices and on plants below
Small round exit holes
Needles fading green to yellow to reddish brown, often fast
Under a bark flap: a small central chamber with long, straight galleries running with the grain
Bark flaked off by woodpeckers, with flakes piled at the base

The detail

What else to know

Stress first

Ips follow drought, root injury, lightning and storm damage. After a hurricane, bark beetle buildup can run months to years.

Why removal is the usual answer

No insecticide reliably rescues an infested pine. A colonized pine that could fall on people or property is removed and its debris cleared, because fresh slash breeds more beetles.

Not the southern pine beetle

The southern pine beetle has never been recorded in South Florida. When someone names it here, the beetle is almost always Ips or the black turpentine beetle.

What we do

How Ptolemy handles it

Field condition first, then the recommendation. Treatment, removal and diagnosis calls are made by an ISA Certified Arborist, and the serious ones are confirmed in a lab.

Written down before it is neededThis is covered by our pine bark beetle protocol.

A field check: tube size and height, boring dust, exit holes, crown color, and a look under a bark flap.
Suspected until our certified arborist confirms it on site. A photo is not a finding.
Infested pines that could fall on people or property are removed and the debris cleared.
Protective bark sprays only for high-value pines in the same grouping, on our certified arborist’s call. Never a blanket spray, and never near ponds.
We do not fertilize pines.

FAQ

Questions about ips engraver beetles

Is this the southern pine beetle?

Almost certainly not. The southern pine beetle has never been recorded in South Florida. Here it is Ips or the black turpentine beetle.

Can an infested pine be treated?

No insecticide reliably rescues a pine Ips have colonized. Sprays protect nearby high-value pines before an attack.

Should every pine on the property be sprayed?

No. Only high-value pines in the same grouping as an infested or stressed pine, chosen by our certified arborist. A canopy mist does nothing.
