This beetle occur throughout the Nordic region except in Iceland and the farthest north. Violet tanbark beetles are at most 16 millimeters long. Its larvae reside under the bark of wood from spruce and pine. It is not a real pest as it does not affect the bearing capacity of structural timber as it only lives just below the bark.
How to avoid them:
- Clean Floor drains an siphons. Not only with chemicals or hot water, mechanical cleaning is necessary too.
- Throw away rutten fruit and vegetables. Clean the place where the fruit has been carefully.
- Do often and carefully clean the garbage room and the rubbish bins.
- Control ventilaters especially those close to kitchen. They should be free from grease and dust.
Suitable treatments: vinegar traps or light traps.
