Carpenter bees and cedar

[Richard]

I've got a voice in the back of my head saying that I've read somewhere that cedar is naturally insect repellent. If that is not true, the following won't matter.

If it IS true.... then here's my question. Wife at an estate sale, came across a number of rough cut boards. Person told her they were white oak. Well.... they're not. Be that as it may, there are several rough cedar slabs. Still has bark on outside edges.... I've got ability to cut/plane...so here's my question finally!

If I cut these up and make some bee traps, because they are cedar, will the carpenter bees avoid them or will that be an issue? These are about the right thickness to do this. If the bees would avoid them simply because they're cedar, I can use some of the other boards she's got but have to plan them down further....

I'd rather plane the boards down and have some traps that work instead of using what I have and the (*#&$FC"EWR bees avoid them, rendering them useless!

Anyone know?

Thought I'd mention, I looked online and found:

"Carpenter bees are attracted to cedar wood and prefer untreated, unpainted wood. To prevent infestations, consider using carpenter bee-resistant wood, such as cedar, redwood, and pressure-treated lumber. Carpenter bees burrow into woods to build a nest for themselves and their offspring, so it is crucial to protect your property with simple prevention and control tips."

So, they are attracted to cedar..... but to prevent them, use cedar?

House here is cedar sided with some redwood used for decking and trim.

Carpenter bees seem to have no issues with burrowing into it to make nests/lay eggs.

Wood is old though (built in ‘69)
