is there a way to poison hosp which going into a outside tool shed, these are the same hosp which torment my martins,the poison food would only be accessible to hosp as i've never seen any other birds in there,it would be on a elevated platform,my repeater trap is just not working nor is my pellet gun,if anyone has any ideas that would be great, my martins returned on saturday 4-21-07 and the hosp are tormenting them....jerseyjoe
Doubtful you could find a good poison. I had a rat in my garage and couldn't get rid of it because they don't sell the fast acting poison anymore. This rat carried the poison chunks away and stored it, but it must have ate a little as it finally wasn't there anymore.
Anyway, even if you had a poison in mind, you wouldn't be able to ensure that wrens wouldn't go in there, because wrens DO nest inside buildings. Just stop the holes up so nuthing can get in there and you can catch them and use a bluebird house trap or similar and you should be able to catch them.
I think Diazon granules have a cautionary statement about birds, maybe you could mix the granules in with bird seed. Just be sure it's only house sparrows getting to it.
Working for a rancher in my younger days I I used to mix "portland" cement in with ground corn,white millet, and milo and this took care although painfully I would imagine, with all the barn nesting HOSP.
Be careful with pigeons,doves and other barn nesting birds.
The HOSP will pick and scratch but will always get enough of the portland to do the trick. However, I refuse to use this method UNLESS the birds you want to eliminate are captive to the barn or shed or building.
THIS WILL WORK.
One real drawback to the idea of selectively poisoning only House Sparrows (HOSP) is secondary poisoning of any other animal or scavenger that happens to find and eat dead, poisoned HOSP. This could be anything from a cat or dog to skunks, possums, a vulture, etc. Poisoning is not a very practical option for dealing with HOSP or starlings.
Louise, that's true about secondary poison, but how about the dog food that killed thousands of pets across the country you can still buy this at pet stores again just look for that lot number so many stores still carry it. Again you need to target those starlings because they would be the one to eat it along with white bread, mixed it together but again use caution.
