I've got the "Beltraa" traps in the hives, they hang beside an end frame, look like linoleum on the inside, got a few beetle size holes in em, on the box side they are fluffy (you scratch em up with a wire brush before you slot em in), so they do same thing as the chux, without the bee risk. The idea is the bees chase them in.
The Aptithor traps with the attractant and the enclosed Pesticide are supposed to be good, but I hear the bees keep on sealing them up with propolis in days. The small hive beetle infestation arrived from USA in 2000, and started only about 20 km away, as the beetle flies, so I guess we just have to live with them permanently now.
Dermot, you have depressed me with the story about them all flying in, I try to keep openings to a minimum, but have to harvest again soon, having such a good summer . . . .
And yes, Lone, it's a pity it released the beetle, I imagine the poor bee putting the same beetle out over and over again. I suppose you haven't got beetle up there yet?
