Lisa You will be losing sleep and pulling your hair out before this is over. I have not worked the last few years so I do nothing but watch out the window during nest building. I have seen these situations more than once. This year I am working and can only hope while I'm gone tragedy will not strike. Running out screaming and waving at hosps is always a good tactic. LOL It does work. First Keep trying with the drst. The natives will not go in it again after they get caught. The titmice always bite me when I let them out. So cute! I like to put it near a brushy area where the hosps hang. Next shoot at them with the bb gun every time you see them at the box. You will find out they are very smart. Even if you don't hit them you can sway them to another box by doing this. I would try to notice where they are flying in and out of your yard from and situate the drst there and also put another box with a 1 1/4" hole near there to see if I could entice them to switch boxes. Then let them get comfy and keep them busy. Then use the Van Ert. Of course like all traps it still must be monitored as other birds fit through that hole. You have to stop feeding the other birds or use only safflower seed when using the drst. Once they get busy nest building for real they will be more apt to eat from the trap. Keep us posted on your situation and your sanity. Any questions don't hesitate to ask. Good Luck Cathy

About a month ago, Bluesman posted on the Bird watching forum about a type of entrance hole that allows Tree Swallows to enter, but not HOSP. He said - "There is a House Sparrow resistent entrance to keep them out of Tree Swallow houses but unfortunately Bluebirds cannot get in this. It works great for Tree Swallows though. I will see if I can post a picture of it. I first heard of it from a man in Canada named Bernie Nikolai. It is simply a 7\8 of an inch tall slot that is about two inches wide. It is in a thin plate around 1\8 inch thick. The House Sparrow cannot enter this but the Tree Swallows being more streamlined and slender bodied can flatten out and get right in. It works so good."

Sounds like you really have some challenges. You have my sympathies! A tiny poked hole is more likely a house wren's thin sharp beak, sometimes taking them some distance away, or simply tossing them out. The house sparrow will toss the eggs out, but their finch-like beak would not as likely make a tiny poke hole. And the HOSP is more likely to stick around, harass, or even take over the cavity. "Do BB's destroy their own eggs" ... No "the nest possibly could have been flooded?" ... are there leaks that could be fixed? "Are the HOSP really sneaky" ... yes, but HOWR are sneakier ... "and resistant to the Sparrow Spooker?" ... yes, and house wrens will not be deterred by a sparrow spooker. House Wrens are even sneakier, faster and silent, leaving no evidence behind, only destroying eggs or young. You might hear them singing, but might never, ever see them! There are some links to sound files of house wren song and chatter on Bet's web pages, so you can learn to hear the unwelcome sounds of house wrens. Visit Bet's web page for more info. And by the way, the Carolina Wren is a very different bird, welcome almost anywhere; not a threat to other birds. BlueBars Here is a link that might be useful: http://www.sialis.org/index.html

BlueBars, I nearly had a heart attack! First I found the dirty water in my dogs water bowl and then I found the paw prints! I took photos and my exterminator assured me they were raccoon paw prints! He lives in the country and shoots and traps coons all the time so I knew he'd know. My dog sleeps upstairs in bed with me so she never heard a thing and my hubby travels often and was out of town. The only thing that I hated was that he (HUBBY) didn't walk into the kitchen in the middle of the night to find that raccoon! LOL! That would have been the last straw with my obsessive bird feeding! First we had roof rats (yep, I was told to get rid of my back yard feeders) and then the raccoon! I find it amazing that the raccoon went through not only one dog door but two. He had to enter the screened in porch through one, then go through the next one into the kitchen! Ate the dog food, washed up in the water bowl and went right back out the way he came in! LOL! The dog doors are always closed off at night.... now!
