Beeswax polish. No. Citronella. No.
You could try buying some swarm lure from somewhere like Thornes. I've never had any success with it myself but it's better than nothing and is probably the best option for a new, empty hive.
Other things I've heard of being done is putting a few spoons of
local honey inside, and 'scraping' the inside with a block of pure beeswax. I've tried both out of curiosity in the past, again with no success. I've even tried a couple of homemade swarm lure recipes (from the internet), but again nothing.
The best thing is to put clean drawn comb in there, perhaps you have a beekeeper close by you could have a chat with? Although, very unlikely he/she will have a Warre hive so their kit won't necessarily be compatible with yours if that's the route you decide to go down.
BUT if you are able to get hold of drawn comb, the next concern is that it is free of disease.....
....join your local beekeeping assoc - that's a must anyhow in my opinion - as besides making contacts you will learn a lot about bees.
