How do I catch an acro crab before redbug treatment??

[bct15]

I noticed I have redbugs last week and have a treatment coming in the mail, no tracking but I'm assuming it will arrive mid next week. I have a relatively large acro colony with three acro crabs in it (two tiny ones about 1/8-1/4 inch and one medium sized one about a half inch), the branches of this colony are very tightly packed together and I can't get a toothpick in there without damaging the coral, much less a pair of tweezers to get out the crabs. I would like to remove the crabs before treatment but have no clue how to get them out, and I don't want to risk losing the coral trying to catch these crabs out of there. Is there a simple way to coax them out without damaging or risking the coral? Is there a chance the acro crabs will survive the treatment if I can't get them out?

Here is a couple iphone pics of the colony I am talking about

Thanks

No chance they will survive the treatment.

Most people take the acro out of the tank, and chase the crab off with a toothpick over a bucket, but it seems you're aware of that method. I'm not sure you have much alternative. Perhaps a blast of freshwater from a turkey baster over a bucket might work too? But I'm not sure how much that might harm the crab; might be worth a shot though.
