B 1076— Worms in Oak Floor 



Chicago, November 17. — Editor Hardwood Record : We have a letter 

 "from ODe of our customers, wherein he states that after ten months he 

 has noticed that worms were working on oak flooring very badly, and 

 would eat out the center and just leave the shell. Can you tell me the 

 ■cause of this trouble and advise a remedy? This is the first case, to 

 my knowledge, where worms have damaged oak flooring after being laid, 

 as, to my mind, the kiln-dried process should kill the worms. 



Can you tell me If worms will work into maple flooring after It has 

 been laid? If you cao give me any information along this line. I will 

 appreciate it very much. W. L. Claffey, Secretary, ' 



Oak Flooring Manufacturers' Agsodatton, 



All Three of Us Will Be Benefited if 



The damage described in above letter is apparently due to the 

 activities of a minute insect known as the powder post beetle. 

 There are several species of this insect, but all of them work in the 

 same way. Their presence in wood is no proof that the lumber was 

 not well kiln-dried, because the insects enter the wood after it 

 leaves the kiln. They seldom or never work in wood that is not 

 well seasoned. Hickory suffers most from their attacks, but they 

 will enter several other kinds of hardwood, oak and ash in par- 

 ticular, but also others, including maple. 



The beetle originates from an egg deposited on the surface of 

 the wood, or in a crack or other small opening. The boring is done 

 while the insect is in its larval state, in that stage resembling a 

 worm not more than a sixteenth of an inch in length. When it 

 attains maturity it has two thick wings, two thin wings and six 

 legs. It emerges from its burrow and flies away to deposit its 

 eggs in dry lumber somewhere else. 



The insects are hard to combat after they have entered the 

 wood, for it is then diflScult to reach them with dope of any kind; 

 but if the wood has been sprinkled with kerosene, the beetles will 

 not deposit their eggs there, and that is the best method of 

 prevention. 



The writer has had personal experience with powder post beetles 

 that infested the oak finish in a house and were present by thou- 

 sands in window and door frames, washboards, chair boards and 

 picture molding. As a remedy the woodwork was washed with 

 kerosene several times, and the insects quit working, whether the 

 kerosene killed them or whether they had run their course and de- 

 parted, cannot be stated. They never returned, and the woodwork 

 is still doing duty, fifteen years after. It is probable that the 

 vapor of kerosene penetrated the burrows and killed the insects. 



No specific instance is recalled where maple flooring has been 

 damaged by powder post beetles after it has been laid; but any 

 flooring is as liable to attack after being being laid as it was 

 before, except that the mature beetles are apt to be more numerous 

 in a lumber shed than in a new building. — Editor.
