Type of palm trees most attacked by Red weevil

Red weevil treatment
Palmera canaria (Phoenix canariensis)
This is the species that is most frequently attacked by this pest. In fact, palm trees that are not fumigated with phytosanitary products, sooner or later, will be affected by red weevil.
Date Palms (Phoenix dactilifera)
It is the second most affected by the plague. In this case, although there is a minimal probability of affectation than with the previous one, it is still very high. For this situation, we recommend a treatment using organic products and fumigation with phytosanitary products.
Palm (Washingtonia robusta or filifera)
This is the species least attacked by the red weevil. So much so, that it is strange the time we find the affected palm tree, although it is possible. On this occasion, we recommend acting when we observe symptoms of this pest.
If you have any of these types of palm trees and you think they may be infected, call us as soon as possible. Every day counts.

Phases of red weevil infection

Weevil treatment initial phase

Early stage weevil infection


In this phase, with the naked eye we can observe a small deviation of the main eye of the palm tree, that is, in the nascent leaves. Also, we will find bite marks on some of its leaves in a triangular or circular shape.


At this time we can visualize a greater deviation of the main eye of the palm tree. Also, there is a decay in some palms caused by the loss of their natural rigidity, due to the fact that weevil larvae are beginning to eat the attachments of the palm to the trunk.

Critical stage weevil infection


Arrived at this circumstance, the palm tree is in a critical state. This means that, in the event that the copy is saved, it will be marked for life. The main sign of affectation that we can find is a pronounced inclination of the palm tree's main eye. Therefore, if a correction is not applied in time, it could rapidly evolve to a Phase 4, converting its possibility of recovery to a fairly low percentage, and could even end the life of the specimen. In this phase, a quick action could determine the salvation or not of the palm tree.


It is here that we enter the last phase in which the palm tree would have some chance of recovery. This probability will depend solely on whether the weevil larvae have touched the specimen's bud or not, or partially. In the event that the bud has not been touched or is partially touched, the palm tree will have to be carefully evaluated to plan the best possible performance. Visually, we will observe the main eye of the palm tree completely fallen, even looking practically towards the ground. Likewise, the vast majority of the leaves that accompany it show signs of decay.

End-stage weevil treatment

End-stage red weevil infection


In this last phase, a professional can verify that the larvae have finished off the specimen's yolk, thus making the recovery of said specimen unfeasible. The visual aspect of the palm tree in this case is very similar to that of Phase 4, depending on how long it may take in this situation, we can find the main eye of the palm tree completely detached or the palms completely decayed or dry.

Therefore, at this point, the only thing to do is talar la palmera.

If you think any of your palm trees may be infected, call us as soon as possible. The sooner we evaluate it and act, the more likely it is to recover.

Palm Palm Fumigation Methods for the Treatment of Red Palm Weevil

Spray gun

By spraying with a gun we achieve a very effective result, since the angle of application is wide. Thus, it allows that with a good application all the part to be fumigated is covered. In this way, we will leave the palm trees impregnated with the product to prevent the setting of the weevil.

Red pole weevil treatment

Pole use

This method is used for the tallest specimens that cannot be reached with the pistol due to their short range. The pole allows us to reach it because its sections position the application tube at a much higher height. In this way, thanks to the pole, we will be able to fumigate the entire wall and central leaves of the palm tree.

Injections or endotherapy

To carry out this technique, we use injections that pierce the trunk of the specimen and allow the product to protect the specimen from the inside. From the company we recommend that in specimens of Phoenix Canariensis if you want to use this method it is also complemented with some spraying.
