I'm hoping there will be some bee experts around to help me...
Yesterday i kept hearing a single buzzing noice on and off, coming from a old vent in our floorboard/carpet (the vent was used when we had a back boiler). We blocked the vent with card board when we had our new combi boiler 2 years ago as we were told this was ok to do. I also saw a hugh bee (like a big bumble bee) coming in and out of an air brick not far from the vent.
Today i saw the bee again (there only seems to be one bee) coming and going. After it came out i blocked the air brick so it couldn't get back in and it's been trying to get back in for a while.
I'm not sure if i've done the right thing. I was hoping it would go and make another nest elsewhere...but will i be too late and will it have already laid eggs that will hatch under our floorboards?
I will be grateful for any advice.
