Reply To: Wasps
If wasps have found a weak colony they will predate on it mercilessly. You can reduce the entrance size but early in the cool mornings when bees are clustered the wasps are flying and able to get in. There are decoy entrances on the market or you can make your own using electrical trunking. They can help. The best solution is probably to move them as you have surmised.
A weak colony is always vulnerable. I have seen lots of wasps in one of my apiaries and they have finished off a weak nucleus colony. The other strong colonies have small entrances and are keeping them at bay. Check your colony when it is in its new location to see if it has a problem. Is there worker brood present in reasonable volume? Is the queen present and laying? Any signs of significant disease?
