Lid or no lid after cutting/pipping?

[DooLittle]

So it turns out it was 2 Lessers after all!
How long does it usually take for them to crawl out once you cut? As i said we cut on day 55.
Appreciate your reply as we're dying from impatience here!

Forever. :p

I had one crawl out that night, and the rest trickled out over the next few days.
