Rather than close the hole, make a cone out of window screen with a half inch opening at the tip and secure it over the hole. Make the base tight enough that bees can't crawl under it. If the hive survived, the forragers will be able to leave but not return. Eventually they will dissapate as they cannot survive without the returning foragers.
Later this summer, remove the cone for a month or so so that any bees in the area can enter and remove any leftover honey. By then swarm season should be over and you don't have to worry about them moving in.
This fall patch the hole.

If you have no bees now then you guessed right....DEAD!
If you leave it, then a new swarm might find this new home during summer.
It would be best to open the wall and scrape everything out first before sealing tight,
there could be allot of dead bees with mold growing, you could harvest some honey for the effort.

Need help getting rid of honey bees around my koi fish pond they are on the side of the waterfall and in green plant that sits in water. Daughter is 8 and loves to go near the pond dont want her getting stung, any ideas what I could do to get these pesty critters to go else where. Have to be careful what I use so I what harm my fish.

Can you post a picture?

Can"t post photo on here but I could email it to ya, send email address..

gonecrazy09,

The bees you see are probably foragers seeking water needed by the hive. Foragers are not generally aggressive, and there should be little danger. This would be like bees in flowers, or on clover in the lawn. If your daughter steps on, or grabs a bee she will get stung, otherwise I would not worry. You could try providing a bird bath or other source of water up high, try putting some sugar in it, but the bees may continue to prefer the pond.
