My concern about sonic devices is for
any resident animals in the home. We all know
their hearing is so much stronger than ours.
I've done some surfing around the web looking
at pros and cons and there's a lot of info
out there. (I Google, therefore I am...;-)

True, and even if directional, I wouldn't want to subject my guys to
that. Of course, the cats would think the same of a sprinkler. I wonder if a
floodlight and recording of a barking dog would have any effect on a
raccoon? :-)

Well, my sonic system is directional and only comes on when there is
motion around the pond. You set a dial on the box to adjust the
frequency of the sound for the animal you want to annoy. The range
seems to be 25 feet. And my cats, who stay in the house, 15 feet away,
don't seem to even know it is even there. I have not heard the
neighbors dogs react to it either.

I went from torn up plants, over turned rocks and scared fish to no
problems at all.

Do your due dilligence and decide for yourself. I'm not giving advice,
merely stating facts as they apply to my situation.

havahart makes a motion detector sprinkler called a spray away. i got
it from ace hardware and it was only $50 instead of the $89 ive seen
elsewhere. good luck!

I read a lot here. I was wondering if anyone has ever used 1/4 inch
plexiglass over the top of a 200 gallon round pond? I would mount it 1
inch above the pond. My only problem id would condensation form inside
the plexiglass? I can put a hinge lid and anything else needed for
cleaning ect. I just dont like the net idea. Raccoons can eat through
that. Ant ideas would be great. Thank you.


Sounds interesting. I've seen ponds inside a greenhouse.

I have been using a thin black plastic mess netting - the type sold to
cover fruit trees from birds. Its been working very effectively for
the last two years at keeping Robby Racoon at Bay. It is very cheap as
well. plexiglass would be quite expensive, and very obtrusive in my
opinion.
