I have moles tunneling under my patio block sidewalk and causing it to
sink. I do not use any chemicals for pests, since the chemicals are
usually more harmful than the pests. I am looking for a non-chemical
substance to put in their tunnels to either kill them or repel them.
I prefer a natural substance such as a toxic plant. I WILL also use
something like diesel or another petroleum product, just not poisonous
Thanks in advance.
Yea I know petroleum is poisonous, but not in the same sense as cancer
causing chemicals. I dont intend to dump gallons of it, just a half
cupful or so to burn them out. But I think the mower exhaust sounds
like a better idea..... Taht way there's no actual fire, just the
smoke which is what I wanted to achieve. I even have the perfect
mower, the old worn-out engine burns lots of oil......

I have very good results with the mole bait poison. It's zinc
phosphate. I don't understand it but they eat it. But you didn't
want to use poison. Given dumping petroleum verses putting a little
bait in their tunnels I think the bait solution is less offensive.
But you can't let dogs get at it though, apparently they will eat it
Nothing else worked for me.
To answer your question: What you need is a trench around your porch 4
feet or more deep. Put heavy duty wire mesh with sufficiently small
openings that a mole can't get through (1/2 inch should be fine enough)
in there and anchor with concrete footings. Fill in the trench. There
are also mole traps you can buy (LeeValley.com ??), but they may not help
enough, because there are apparently dlectable bugs under your porch.
I'm cranky, but don't let that affect you. If you think diesel or toxic
plants are fine, but poisonous chemicals are not, you should go and get
your tuition payments and school expenses reimbursed, because your
schools failed to educate you.
That's hard to believe, given the size of your average mole and the
amount of earth that they'd have to excavate in order to destabilize
patio blocks of arbitrary size.
And I wouldn't expect them to build a home under a high-traffic,
Give them something else to burrow under.
Or get a cat. One of our cats usually bring us 4 or 5 moles a year
(from our back yard). I must say that moles (unlike mice) are
particularly nasty - they universally refuse to be taken alive.
Run a hose from your lawn mower's exhaust to a mole hole. Run the machine
for fifteen minutes every day. With a long enough hose, you do this while
you cut the grass.
Poke some lumps of calcium carbide down the hole as far as possible. Squirt
some water in the hole. Cover the entrance for five minutes. Open the
entrance and fling a match down the hole.
This latter may not kill any moles, but the exploding acetylene should level
Our local State extension agent told us the most effective means is
patience and mole-traps. She said she had had marginal success with
most poisons; but flooding was a long shot approach.
The mole(s) had shown up overnight and and already produced 4-5 mounds
with some visible tunnels. Before I sprang for a trap, I tried
flooding. Poked the hose in all of the mound openings and then ran it
into one of the more visible tunnels. I had water coming from all of
the visible mounds and tunnels (about 30 minutes work). No more
I already tried to flood them out in other places around here. Seems
they just go into another tunnel. I once stuck a hose in a tunnel and
left it run for 2 or 3 hours. Later that day the water finally
started to come out of the ground at least 200 feet downhill, and
there is a barn in between. Past the barn I could see some sections
of tunnel collapse after I turned the water on again. But the moles
I do sort of like the idea about the exhaust from a lawn mower.....
I think I heard that mentioned somewhere before too.
I should mention I bought a trap for about $15. Biggest waste of $15
I can think of. And it was in a major tunnel area directly into a
tunnel. Just like the instructions said.
I have cats, they dont seem to catch them often. I did see a cat get
one mole earlier in the spring. No thanks on the dogs. They dig
larger holes than the moles and I cant stand barking.
Moles rarely if ever make a mound; their runs generally are shallow
enough that the tunnels just leaving a raised surface in continuous runs
is generally the symptom.
Many mounds and a few tunnel tracks (maybe) is sign of pocket gophers;
they burrow deeper and break through leaving a sizable mound a place or
two every pair most nights while active.
If look at those mounds carefully, you can generally find the plug where
they've refilled the egress hole; remove that carefully and you can open
into the tunnel w/o disturbing it. When do so, place some bait in the
tunnel, again being careful to not seriously disturb the dirt. IME,
that's nearly foolproof; they'll either take it and be killed or they
will depart the area.
Being able to put enough water down a system to bother is rarely
effective; unless it's a new system they will have already built air
locks to prevent flooding; after all, they've survived heavy rains and
flooding for millenia; they either read the engineering manuals or have
good instincts, I'm not sure which... :)
That seems _most_ peculiar as, as another noted, they feed on earthworms
and to lesser degree grubs and other insects that generally are feeding
of sod roots, etc., that are only a few inches below grade.
The deeper runs are the permanent ones but I rarely if ever see moles
actually mound. OTOH, we are run over w/ the pocket gophers that only
appear in mounds their tunnels are deep enough never see the traces of
them on the surface. The gophers are stout enough they even just pop up
through the gravel roads that are packed quite hard, obviously. It's a
real shock-absorber test to hit one of those mounds if can't avoid it
owing to traffic (or not paying much attention being more like it :) )...
