You can wait until they burrow using Tuxedo-Templar's 'dectecting defiler' trick. But this means another method of placing lurkers, such as dropping a marine out of a dropship, loading the marine, and making the lurker. (Not much of a differnce from making them stay burrowed anyways).
There isn't a tutorial on it, so I'll make one later

. As for now, here it is.
Create a small location (16x16 pixels is good).
Create a 3x3 location.
In some area that no one notices, or that no one can even see, place a zergling.
Constantly center the location on that marine which you have in the dropship for creating lurkers.
..wait..
I doubt you want to do this, so just tell me in the thread if you want me to continue with my method.
