how long do they last? home is about 30 years old, wall must be same
age...


My house was built in 1986 and the front yard was landscaped with RR
ties. I'm in the central valley of CA (HOT, bone-dry summers; wet,
foggy, cool winters.

As of the last few years, the RR ties are deteriorating badly. Totally
infested with roaches and other bugs, albeit no termites.

I guess 22 yrs isn't bad, but the bug infestation isn't pleasant.
