    I lost my house and my orchid collection of thirty years in the Tubbs Fire in 2017. I have rebuilt my house and am now starting to restock my greenhouse. The problem is that when my new plants have a spike or a flower is about to open, it is eaten my mice. I have trapped a few and caught a few on glue traps(a most unpleasant solution), but there seems to be an endless supply that come to replace them. The only solution so far is to suspend plants from the greenhouse roof where rodents can't climb. As my Vandas start roots they are devoured. Has anyone had success at permanently getting rid of rodents in their greenhouse. I am open to suggestions.

    I had Roof rats get in my greenhouse. The only solution was to find every hole that they could possibly come through and plug it. Don't leave your door open, ensure there is no gap under your door when it closes, and make sure windows and vents are screened. They can get through tiny holes.
    Good luck.

    I don't know the design of your greenhouse but perhaps it can be sealed so that rodents cannot get in. There are a number of passive traps designs in youtube, that can decimate even the most prolific rodent population. But if artisan massacring of mickey's brethren is not acceptable, perhaps you can get some help. Here is a photo of the one that helps keep my orchid growing area rat free. As a pleasant added bonus, I haven't had plant theft in ages.

    Yes, I had garter snakes in my greenhouse. They were quite effective at keeping the rodents under control.

    They were not, however, a deterrent to groundhogs, so trapping and relocation was necessary.

    Your best bet is to make the greenhouse impenetrable like others suggested (seal any gaps or holes, wire screen on vents / windows, etc). Then you'll need to keep traps going and/or use poisons (if there are no pets / children around) to ensure there's not a breeding colony in the greenhouse.

    Mice use urine trails to communicate and navigate with. The smell of urine protein / pheromones of a past infestation will attract newcomers, which may explain part of why there seems to be an endless supply. There are also commercial products you can spray which neutralize the urine smell, and there are homemade remedies that may help.

    Living in farm country where household invaders are a fact of life, it's very common for people to plant various kinds of mint, and especially peppermint, around the foundation of their houses. Apparently it acts as a deterrent for mice. Folks also spray peppermint oil indoors or put out peppermint oil diffusers in areas where the mice scamper indoors. It won't get rid of mice if they're already there, but apparently it can dissuade them from coming back.

    We have had great success keeping mice out of our cottage by placing moth balls as well as bait stations around the perimeter. Moth balls seem to be particularly effective.

    First, I am very sorry to hear about your losses.

    Choose your method of exterminating the animal. After you seal any possible entry points, spray the outside perimeter with ammonia to keep them from trying to follow trails. I've had 2 infestations of rats. One about 25 years ago and another last year. The ammonia spray is critical. Without it, they will dig or gnaw until they get in to follow old trails.
