Bark beetle - a bug, though small, but very annoying, it is difficult to control it. Indeed, it is not so easy to destroy insects living not on the surface, but inside the trees. Bark beetles (combating them is a complex procedure) affect garden plantings, causing the death of trees. They do not disdain wooden buildings, so your house is also under threat.
It is difficult to track the moment when a bug only settles in a new place. Usually, a pest is found already in the wake of its hectic life. If you saw small round holes dusted with sawdust dust on
a tree trunk or on the floors of a house, be sure that these are bark beetles. The fight against them should begin immediately, otherwise everything will end in complete destruction. Broken insects will simply eat wood, and the fact that they do not have time to chew will destroy the fungus that appears in the voids.
Now we dwell in more detail on pest eradication methods. First of all, do not neglect prevention. Do not leave dry and damaged branches on the tree - they must be cut and burned immediately. Carefully cover the cut points with garden varieties. Carefully inspect the trunks - so you do not miss the first signs of damage to the cortex.
Measures to control bark beetle include chemical treatment of trees. Spraying is best done immediately after a flowering period. It was at this time that a mass departure of beetles took place. Repeat the procedure after 14 days. Thoroughly coat the solution with every centimeter of the surface. Trunk, twigs, leaves - do not miss anything.
Preparations for combating bark beetles include such as Decis, Vectra, Aktara, Calypso, Confidor, Sherpa, BI-58. All of them contain toxic substances. When working, be sure to put on clothes that completely hide the body. Get on a respirator, rubber gloves, goggles. And do not step back from the instructions attached to the insecticide!
In addition to external spraying, good results are obtained by pumping the poisonous substance directly into the passages left by insects. A syringe is useful for these purposes.
And what if the bark beetles settled in the house? Fighting them will be more difficult, because you are unlikely to want to arrange a
chemical attack in a residential building. But you cannot leave everything without intervention. A collapsed
ceiling beam, a failed floor is the result of ignoring the problem.
In the event that the lesion sites are only outlined, it is possible to inject low-toxic drugs (“Confidor”, “Antizhuk”, “Vektra”, “Antishashelin”) with a syringe into the holes made by parasites. Instead of chemical insecticides, sometimes used drying oil, engine oil. Care must be taken to ensure the integrity of wooden surfaces. Any damage immediately paint over or cover with the same drying oil, stain. In advanced cases, you still have to call professionals who will conduct a comprehensive cleaning of the house. But you have to leave your home for a couple of days.
Of course, bark beetles will not immediately leave you. The fight against them should be regular. Only then will it be possible to succeed!
