Hidden existence

barbel beetle on woodThe habitat of barbel beetles is often hidden from the eyes of people. Insects live and can reproduce in different places, the main thing is the presence of wood. Often their home is:

  • tree trunks;
  • shrubs;
  • herbaceous plants;
  • human dwellings made of wood.

The female lays eggs in small cracks in the bark of tall trees, in the depressions of young shoots or in the trunks of shrubs. Often they themselves make these indentations for settlement..barbel beetle larva

With the help of a strong jaw, the female makes a depression in the wood and lays about 300 eggs. After a few weeks, larvae emerge from them, which live for about 17 years. Biologists say that during this period they can make a tunnel 40 km long in the trunk or wood. And they will leave their habitat only in the form of an adult insect. Thus, the larvae weaken the age-old trees, which die over time..

Original diet

barbel beetle in the wildWhat the barbel beetle feeds on truly surprises outside observers. Much depends on the type and habitat of the insect. For example, “Lumberjack” loves to eat pine needles, and “Bark beetle” – young branches. In general, his diet, in addition to wood, consists of the following components:

  • pollen;
  • leaves;
  • bark.

  • attic beams;
  • window frames;
  • ceiling rafters;
  • various partitions made of wood;
  • by sex.

It’s scary to even imagine what a house with such settlers can turn into. By and large, it is in this that the danger of the barbel beetle to humans is noted. Otherwise, the insect causes a smile and admiration for its attractive appearance..

Some species of longhorn beetle feed on the sap that the tree secretes. And the barbel “Titan” does without food at all. Therefore, you should not destroy all insects with long whiskers in a row..

  2. If winding miniature tunnels are visible on the surface, this is a sign of an infected product..
  3. The bark is easily removed from the surface of the trunk, which means the beetles are somewhere nearby.
  4. Brown or yellowish dust indicates large colonies of pest larvae that abundantly feed on wood.

protective wood treatmentThe presence of these signs prompts immediate action. But how to get rid of the barbel beetle and protect the house from irreparable harm? The optimal solution is the processing of wooden building structures with special substances. Otherwise, the beetles will freely enter the new dwelling. However, in some cases, builders overlook to do such processing and over time pests settle in wood structures..

You can check for barbel with a screwdriver. To do this, you need to pierce the wooden surface of the building. If it enters freely, it means that the larvae are gradually destroying it..

pestTo eliminate barbel beetles from wooden structures, it is necessary to perform the following work:

  • cleaning contaminated surfaces with a brush;
  • removal of wood dust with a vacuum cleaner;
  • preparation of an insecticide, according to the instructions provided;
  • processing of various recesses, cracks or holes in a wooden structure using a spray gun.

To ensure 100% effect of the chemical, the room is tightly closed for 3 hours. After the specified period, be sure to ventilate for at least 6 hours.
