I have ave a bucket from last fall. Should I use them to dye some of my traps or use the longwood dye packet?

chestnut or walnut hulls? Never heard of using chestnut hulls.

Horse chestnut and buckeye hulls work for dyeing fabric and yarn and should work on traps. I know they dye your hands good too. My brother, cousins and I shucked a bucket of them in our teens, that we collected in the park by our grandparents' house.

I don't know if American and Chinese chestnut hulls would work. They are not closely related to buckeyes and horse chestnuts. I have had little access to them to learn about them.

I think black walnut husks would work better than any of the above. That's what I have always used on my traps.

What kind of chestnut hulls do you have?

Log wood

I don’t know about others but I have always been partial to local natural dyes not to mention there free for the taking so I would save the logwood for some time when your pressed for time

Black walnut hulls work very good and they're free, maple bark works too, probably lots of stuff works...

I just use the black walnuts from my yard, free and it works good

I've used black walnut hulls, sumac clusters (whatever they are called) and maple leaves all with good success.

I used hickory nut hulls once. It got the job done, but took a lot more that walnut hulls. Now I use sumac berries.

Oak leaves work as well.

Green tree leaves work ,I use walnut and white oak leaves.
