Sounds like the checkerboarding worked. If you are not planning to split then it's time to "open the broodnest" to slow the urge to swarm.

We are in similar climates and this year the swarms seem to be at least 2 weeks later than "normal". We usually start getting swarm calls at the beginning of May. Haven't heard a peep yet. Should be very soon now. Keep an eye on your brood nest area and don't let them backfill.

Mike,
From my readings, I thought the whole purpose of checker boarding was to eliminate the need for the laborious "Opening of brood nest"?

Glad it worked for you. Checkerboarding works here for me too. Sometimes it ends up being a little later than I would like to do it because of the weather.

I also like to go into the broodnest and open it up during and after swarm season. To me it's not laborious, but simply part of my spring routine. It helps keep in check those colonies that seem to be more intent on swarming, and the best part for me is the beautiful brood combs I get from the empty frames inserted in the brood nest during the flow.

I know Walt considers this dabbling with the system, but it works for me.
