In remodeling, you never know what you may encounter when
tearing out walls. It’s the things you can’t see and unexpectedly discover that
can send chills up your spine like a good horror flick. Also, it’s kind of
creepy to think about things moving behind your walls or above the ceiling, after
all this is the sanctity of your home and these are not invited guests. In our
history we have discovered carcasses of birds, cats, possums, and some
unidentifiable species in spaces that make you ponder. In one house there were
a six dead squirrels piled on top of one another that had electrocuted themselves
by chewing through a wire. Squirrels apparently aren’t very smart since they
didn’t depict from their friends’ demise the hazards of chewing, especially on
the same wire. Another memorable incident was the bat cave.
Upon removing to replace
the siding in the peak of a 100 year old home we watched over 100 bats who fled
from their coveted home into the sunset. Upon returning they discovered their
eviction notice and the home was boarded up. Also, more common than you’d want
to think about, we find rat or mouse trails cut into the insulation behind the sheetrock
or fiberglass shower stalls.
What’s more creepy? Discovering what these unwelcome
intruders can do to the safety of your home and family. In the case of the
squirrels, had it not been discovered, the damaged wire would have eventually
ignited a fire in the attic space. In addition to damaging structural or
mechanical components to a house, unwanted animals can leave urine, droppings,
and/or dead carcass odors that may have you perplexed as to what is that smell?
Some rodents can carry rabies. But don’t freak out, here are some
preventative measures to help deter some of these animal break ins:
MICE can fit into an entry hole ¼ inch or
larger.
Likely
entry points: Garage, basement, gaps around utility lines.
Signs
of infestation: 1/8-inch-long droppings; smell of urine; noises
at night; holes gnawed in food boxes.
Best
spots for traps: Along walls; anywhere you suspect activity.
Preventive
measures: Seal exterior gaps with mortar; weatherstrip the
bottom of basement and garage doors; keep all foodstuffs in hard plastic,
glass, or steel containers.
Stopgap
measures: Stuff copper mesh or bronze wool into foundation
cracks.
RATS
can fit into an entry
hole: ¾ inch or larger.
Likely
entry points: Garages, basements, rotted sills or foundations,
damaged or unused drain pipes.
Signs
of infestation: Black, greasy smudges around openings; smell of
urine; ¼- to 5/8-inch-long droppings; nests of discarded food; fur; matted-down
insulation; gnawing and squeaking at night.
Best
spots for traps: Poisoned bait stations outside the house and
around the perimeter of the property line.
Preventive
measures: Eliminate all water and food sources around the
house, including bird feeders and pet dishes; store food (pet and human) in
airtight containers.
Stopgap
measures: Cover entry points with hardware cloth or 16-gauge
steel flashing.
SQUIRRELS can fit into entry
hole: 2 ½ inches or larger.
Likely
entry points: Where dormers meet roofs or where roof shingles
overhang fascia boards. (The second-story men of household pests, squirrels can
jump 10 to 12 feet through the air.)
Signs
of infestation: Scampering noises in ceilings or attic;
insulation missing from spots near eaves; ½- to 1-inch-long droppings; piles of
nuts.
Best
spots for traps: Live traps, clamped in place near the spot on
the roof where they're getting in. Bait them with peanut butter, dried
corn-on-the-cob, or suet.
Preventive
measures: Prune trees away from house; keep roof and exterior
trim in pristine repair; remove bird feeders.
Stopgap
measures: Nail hardware cloth over potential entry points until
they can be repaired.
Skunks: These four-legged stink bombs will easily
burrow under your patio slab or stake out territory in your garage, crawl
space, or basement. Hire a pro to trap them live and transport them elsewhere.
Bats:
Given the opportunity, they'll happily take up residence in your attic for the
summer and leave behind potentially disease-ridden guano as a present. Seal off
their entranceways with a double layer of insect screen and hardware cloth, but
only after you evict them first (Bat species are protected nationwide). Call in
a pro to erect a "bat flap," a layer of screen that lets the bats
crawl out but blocks their way back in.
Birds:
In spring, starlings and sparrows have a knack for building nests in hidden, difficult-to-reach
openings in a house. The louvered vents for dryer exhausts and the openings
behind roof fascia are perennial favorites. Bar them from entering with
hardware cloth. Take down the bird feeders that are attracting them to your
property.
Raccoons:
The masked marauders of the animal world, they'll barge down chimneys and into
open garages or attic vents. Best captured with a live trap baited with peanut
butter, suet, raw eggs, or dried corn on the cob. To keep them from coming
back, cap your chimney, keep basement and garage doors closed, eliminate bird
feeders and outdoor pet bowls, and lock down trash lids with bungee cords.
Snakes:
In the fall, they'll work their way into openings around basement doors or
cracks in foundation mortar, looking for a place to hibernate. They'll leave of
their own accord when the weather warms up in spring. Seal those openings
behind them.
