Before you make that jump, you may need to consider the other side of the story. Many of us are doing very well indeed with porched, tunneled, sreh.
My colony is a good example, but I am not alone. Some of the best, fastest growing colonies on the Forum are also porched, with tunnels and sreh. For the most part, we have just sat back and listened while this has been discussed.
Not only that, but a number of landlords in my immediate area have copied the style we use. Every single one of them has had good to excellent results.
I have few to no problems with starlings entering my housing. The martins seem to love the porched, tunneled gourds with sreh. My colony will just about match any reported in growth, number of fledglings, etc.
I am not alone, there are others out there who can report the same type results.
Now what am I trying to say????? You use whatever type housing, entrance and so forth you choose to use. I will not even try to tell you what you need to be doing.
I am saying we should be careful in discarding a very effective way of doing martins. I am very well satisfied with my colony and do not plan to change soon.
For those who choose to go porchless, I wish you nothing but the best.
