Living with tall, healthy palms year after year
Canary palms retain upright crowns
Canary and date palms maintain solid green canopies without drooping fronds. Systematic treatments stop internal rot so leaves grow upright and balanced.
Growth buds stay protected
Active larvae are halted before reaching the central growth point. Preserving the terminal bud allows the palm to produce fresh, intact spear leaves each season.
Scheduled treatments run reliably
Systemic protection runs on a fixed calendar throughout the high-risk flight period. Trees remain shielded against migrating pests without emergency call-outs.
Red palm weevil treatment in the Costa del SolWeevil larvae bore deep tunnels inside the palm trunk without showing outer damage for months. The structural core turns hollow while the foliage still looks healthy from the ground.
A weakened crown suddenly collapses under high summer temperatures, dropping heavy fronds straight onto tiled terraces or swimming pools. Removing a collapsed date palm in Marbella requires specialist crane hire and mandatory biological disposal, costing thousands of euros.
Untreated trees also spread flying adult beetles directly into healthy palms across neighboring properties.
The right treatment sequence determines palm survival
Spear leaf inspection is completed — Upper fronds and the central spear leaf are checked for entry holes or flattening. Early detection saves the tree.
A licensed applicator is brought in — Applying products against the weevil is regulated in Andalusia and requires a licensed applicator. That part of the work is not carried out in-house — a licensed specialist is brought in, and access, timing and aftercare are arranged around your visit schedule.
The applicator decides the method — Crown drenching treats the leaf bases where adults lay eggs. Trunk micro-injection feeds product into the sap flow to reach larvae inside the wood. Which is used, and how often, is the applicator's call and depends on the palm and the stage of the infestation.
Pruning cuts receive protective mastic — All open cuts and mechanical scars are covered with specialized healing sealant. Exposed sap attracts flying beetles from hundreds of meters away within hours.
Pheromone traps monitor beetle activity — Perimeter traps containing aggregation pheromones are set away from vulnerable specimen palms. Trap counts determine when local flight activity spikes along property boundaries.
Regular follow-up checks repeat every six weeks — Palms are re-examined during warm months to verify spear growth. Repeated applications maintain defense levels against secondary waves. Inspections continue through autumn.

Villa grounds and mature palm gardens receive regular scheduled exterior maintenance along the coastal corridor.
Your questions, answered
Can an infested palm tree actually be saved? +
A palm can be saved if the central growth bud is still intact. Once larvae destroy the apical core the crown drops and recovery is biologically impossible. Whether yours is still savable is judged on site, not from a photograph.
What is the difference between crown drenching and trunk injection? +
Crown drenching treats the leaf bases where adults lay eggs. Trunk micro-injection introduces product into the sap flow to reach larvae inside the wood. Both are applied by a licensed specialist, who decides which the palm needs.
How often does red palm weevil treatment need to be applied? +
Preventive treatments repeat every six to eight weeks from spring through autumn. Winter applications run on wider intervals because beetle flight activity drops during cold spells. Consistent active chemical levels inside the trunk stop reinfestation.
Which palm species are most vulnerable to weevil attack? +
Canary Island date palms (Phoenix canariensis) face the highest risk and suffer rapid crown loss. True date palms and large Washingtonia specimens also suffer severe attacks under heavy pest pressure.
Can palm pruning attract red palm weevils? +
Fresh pruning cuts release aromatic sap volatiles that attract adult weevils from several kilometers away. Trimming is best scheduled during cold winter months when adult beetles remain dormant. Any fresh pruning wounds must immediately receive specialized insecticidal sealant to block scent and entry.
Are treatments coordinated with general garden care? +
Preventative weevil programs operate alongside routine garden and landscape maintenance. Regular exterior oversight ensures palms, lawns, and perimeter borders receive proper water without soaking sensitive crown bases. Scheduled villa programs prevent maintenance gaps when owners are abroad.
What happens if a treated palm continues to show signs of decline? +
Say so, and the crown is re-inspected on site to test spear leaf resistance. If active larvae or fresh damage remain, the applicator is brought back. If the apical bud had already died before the work started, removal and disposal options are set out plainly.
