Polar Mosquitoes and Killer Flying Squirrels

| 1/17/2011 12:16:48 PM

When you live in a house that was built in 1888, it’s best to lower your expectations in terms of anything being perfect. A cat toy ball left anywhere in our living room will roll quickly down to the middle of the floor in front of the fireplace. When I sit on the couch in the living room I can see through to the back door and I’m in awe that it can open at all when I see the angle it’s on relative to the frame. Not surprisingly our house is not exactly airtight and so small creatures can get it. Every fall there is a mass migration of mice into the house. Sometimes the cats are able to hunt them down, but it’s mostly traps and me. Even though Michelle is an animal lover she allows me to take out the mice. As long as I use traps that kill them instantly, they are open territory when they come into the house and attempt to get into our food.

Right now, in January, we have a few mosquitoes in the house. It’s very weird. I always thought mosquito larvae needed water to hatch in. We have no standing water in the house so I don’t know where they come from. I used to think maybe they were breeding in the septic tank then flying back up the drains into the bathroom, where they are most prevalent, but they’d have to get through the trap in the drain that is filled with water. So what, are my polar mosquitoes also amphibious? I’ve given up worrying about it. They seem sort of dozy and don’t bite in the winter, so I ignore them.

For years we had bats living in our roof. We’d hear them scurrying around between the metal roof shingles and the wooden roof. They moved out when we had the siding on our house redone. Luckily the new siding plugged up the holes in the soffit, which is where they used to get through. If I had a dollar for every time I’ve had to lie in bed listening to bats scratching the drywall just above my head, I’d be a rich man.

Our guesthouse built by the previous owners of this house is “board and batten.” This is a building style that should be called “Board and (let the) Bats In” because small animals are drawn to it. The board and batten technique uses wide boards spaced about an inch apart with a smaller board screwed over the spaces. It looks very rustic but it’s not very practical. Wood isn’t perfect and the wood used in our guesthouse is rough-cut pine with lots of knotholes and other imperfections. Also, as the wood has aged it has shrunk in spots, creating large gaps. There are an infinite number of small spaces for creatures to squish themselves through. One wildlife expert told us that if you can fit a butter knife into a slot, then a bat could get in to it too.

When we first moved in, the guesthouse was like a Holiday Inn Express for bats. There were tons of them in there. Usually I have a “live and let live” attitude, but bat “guano” can be hazardous so they had to leave. We had a wildlife expert come out and Michelle made it very clear that she wanted them to be removed humanely. He told me how to do it, and it was an insane amount of work. Basically I had to seal up every hole they were using to get in and out. This took weeks and I was sure to leave one main exit hole for them. Then I had to use an “excluder” as the wildlife expert called it. This was basically a heavy plastic bag (the size of a sandwich bag) with both ends cut out. I attached it around the remaining hole. The bats could get out through the bag but couldn’t get back in.

I really enjoyed your article. It's so nice to read a story where the animals are treated properly, especially when they're coming at you at 400 miles per hour! Also, to Kathie B; flying squirrels and sugar gliders are two completely different animals. Lee R

Thanks for the laughs! A friend of mine has the squirrels in your photo as pets [they're called Sugar-Gliders ].They are omnivores, but they especially love eating grubs and larvae!You'll need to put COMPLETE,trunk-attached netting over any attempts at fruit production,though! And perhaps leave them some as "payment" for being on pest-removal-patrol? Only a rabid one will attack a human, and they do remember who is kind to them.When they're annoyed they make a sound very similar to someone trying to start a car with a low battery.Their scat is almost the same as mouse-droppings. As for mosquitoes, their maximum travel away from their 'birthplace' puddle is about 300ft/100m...and come Spring, they WILL lay eggs in your indoor "pools", including those underground water-traps, and saucers under houseplants.When the time is right, they'll hatch out of the larval stage and rise up the pipes to bite you while you are innocently enthroned on the most comfortable seat in the house!Best to put some Bacillus thuringensis [[aka Mosquito Dunkers (crumbled), or Bt-Israelensis(or other strains)as a liquid]] down the toilet.This will also eliminate the colony living [YES!] down IN your septic tank.And though they only lay eggs in non-flowing waters,even if those same waters will become torrents later on,they seem to know how long they'll have use of it as an incubator.

I also have mosquitoes in the house in the fall. I believe they come in throughthe vent tubes in the roof. Putting window screening over the top is on the to do list.
