I put a classified ad in the local paper. About half my calls are coming from that and about half from referral - either from people I've done removals for or from pest control companies.
I get nothing from the Internet. I put my name on a couple bee sites, Craigslist ad, Freecycle. Zip from those. My tiny $50 classified ad has brought much more than I expected. I was hoping I'd get three or four swarms for my $50, but I'm getting about 20 calls per week (only about half of which are actually for bees).
Who knew that so many people read the wanted section of the classified ads.
The ad reads:
"HONEY BEES WANTED - Swarms removed for free, hives in buildings and trees removed for fee. Call Bill - XXX-XXX-XXXX."
So, if you want bees, you might try that. However, I advise you to be careful what you wish for!
