Do-it-yourself beekeepers:

American Bee Journal issues of May 1999 and July 1999 have do-it-yourself
articles for making a screened bottom board and pollen trap. A bit of head
scratching may be required as you follow the articles, but nothing you
shouldn’t be able to figure out. The May issue covers building the screened
board with debris/mite collector. The July issue covers building a pollen
trap for the bottom board. In the July issue, the author mentions using two
pieces of 1/4 inch mesh hardware cloth for the trap since it is more
readily available. However, Betterbee (800) 632-3379 does carry the 3/16
inch or 5 mesh hardware cloth. Dadant probably still has the back issues
available for sale. Dadant’s email is [log in to unmask]
