Question
Tenemos listones que se usarán en una estructura de postes y vigas. Son de roble rojo y están listos para usarse. Tienen escarabajos de polvo, como se puede apreciar en los pequeños agujeros de alfiler y los pequeños montÃculos de aserrÃn. No se secarán en horno. Hemos aceitado algunos listones y los escarabajos persisten. ¿DeberÃamos preocuparnos? ¿Se irán con el tiempo? Esto se añadirá a la manguera y se cerrará y calentará una vez terminado.

Del colaborador S:
SÃ, se irán después de saciarse y luego se irán al resto de la estructura. No los usarÃa en mi casa. PodrÃas intentar fumigarlos, pero calentar los troncos funcionarÃa mejor.
El daño interno puede ser pequeño o grande. Si los insectos se reproducen y ponen más huevos, y una nueva cosecha perfora la madera, la resistencia se deteriorará aún más. Este ciclo puede continuar, ya que el PPB prefiere la madera más seca.
Es imposible saber cuánta resistencia ha perdido. Por cierto, si compró las vigas, devuélvalas para obtener un reembolso completo. Luego, fumigue o trate térmicamente todas las vigas futuras y evite que entren madera PPB a la casa.
