Some long-time friends of mine live in an old house in Pennsylvania. They have been doing renovations recently, and running into unexpected issues. Some issues are taken advantage of by their cats. Two recent such instances: finding a bird in the basement, and bats in the attic. I take it much hilarity and cat antics ensued with both.
We had bats in our attic this year, too. (And no, I am not using it as a euphemism, although I wish that is all it was.) We had field mice up there 3 years ago, after we had new shingles put on. Apparently, the roofers disturbed some of the soffit panels and didn’t reseat them properly. The mice climbed up (the gutter spouts? assistance of itty bitty spiders?) and nested in the attic over the winter. When that happened, we had the exterminator bait the attic and install some patches to the soffits. That took care of the mice — as far we we knew.
Then, in March of this year, we heard scratching and scurrying noises in the ceiling on the second floor. We thought the mice were back, so we called the exterminator again. He went up in the attic and looked around some; he said the mouse bait was still there, untouched. He thought we might have birds that had gotten in as he saw daylight through a couple of holes. He didn’t think our problem was mice.
(Aside: I don’t go up in the attic anymore. There is only one small hatch to get up there, in a bedroom closet, and there is no way to get an extension ladder in to climb all the way up. A stepladder will go part way, but it then requires a pull-up to get up into the space. Given the ravages of the years, plus the accumulation of…er, heavy thoughts… that is now beyond my capabilities. We should have gotten a hatch in the hallway, with pull-down steps, when we had the house built.)
So, we called in a wildlife relocation specialist because the exterminator only kills insects and small rodents — they don’t harm birds, if they can help it. Chad, the cheerful animal specialist, sealed up the biggest couple of holes he could find from the outside, put screening over others, then set up a trap for birds. In two weeks, only one bird was caught (a hapless, innocent bystander sparrow), which I then released. Chad opined that — given the lack of activity — birds couldn’t be our problem. So he went up in the attic, looked around, and found evidence that either chipmunks or squirrels had been up there. Oh, and bats —a medium-sized colony. The exterminator had missed that — either he didn’t know what to look for, or he didn’t do a complete survey.
Apparently, bats go dormant over the winter, and only really wake when the temps get above 50 for about a week. So, we had to wait to take care of the bat issue, because bats are a protected species, and we couldn’t depend on them leaving until the weather was warm enough. However, we could pursue a solution to the squirrels and/or chipmunks.
He sealed most of the holes, but left a one-way passage for the bats, and a trap for squirrels. He put out poison bait inside the attic for chipmunks. We caught one big gray squirrel in the trap, which was taken to a park far away and released. The chipmunks outside are too numerous to do much about, unless I want to sit in the garden every day with poisoned seed, and a .22 to pick off the ones who aren’t currently hungry. Even with that, we’d only see a slight respite — the neighborhood is full of them, and they are prolific.
(Another aside: bats are generally beneficial. They eat all sorts of flying insects, especially mosquitoes. Considering how wet it has been here this year, we can use the help. However, bat droppings can create problems with diseases and insects, so we definitely don’t want those in the attic. Bats also have a high incidence of rabies, so it is better to keep a distance from them. If the attic was totally sealed, any bats left inside would try to find some opening to get out; bats can squeeze through tiny openings, including tiny cracks between joists and chimneys that don’t necessarily lead outside. That would result in an exciting rendition of “Da Bats Are In Da House!” Thus, the humane, reasonable, and far less adrenaline-inducing approach is to seal up everything but an opening with a one-way contraption so that once the bats leave the attic, they don’t come back in.)
Within a few weeks, the bats awoke, stretched, had coffee or whatever, and presumably left. Chad came back and finished sealing things up. We now have a 3 year guarantee of bat exclusion, and a $1500 hole in our savings. However, the only bats now are in our belfries, and that makes for much quieter nights. As a side-effect, the sealing job means we are unlikely to get any other critters moving into our unfinished penthouse.
(Aside: Chad said the bats have their young in late spring — he can’t seal an attic from then until early autumn, because the young may be trapped inside. Baby and juvenile bats may die without their mothers, or surrogates. Thus, there are two “seasons” for bat exclusion — early spring, and fall. And no, I was not going to nurse baby bats all summer. so we had to move quickly to get the exclusion done. )
Now, the only critters around here are the chipmunks (digging holes in the garden, and under the sidewalks), one remaining small grey squirrel (at least one other was taken by one of the red tailed hawks that lives nearby — much cheaper than the wildlife relocator), lots of bunnies (minus whatever the hawk gets), way too many mourning doves (minus… you got the idea), and other wildlife. We live in a suburban area, but seem to have plenty of wildlife, including a family of shrews that lives in my compost heap, raccoons that keep knocking down our birdfeeders (I think they are in a gang), some ducks that tried to nest in our pool, toads and tree frogs, and sometimes flocks of starlings, which we try to dissuade. We also see many robins, red-wing blackbirds, chickadees, hummingbirds, cowbirds, goldfinches, house finches, cardinals, and the occasional grackle visit our feeders, as do the mourning doves. We hear bluejays in the distance, but we are too far from the woods to get them to visit up close. Last year we had an oriole visit, but we’ve seen none this year. In the general neighborhood, we also see Canadian geese, several varieties of ducks, and heron near the ponds, and swifts occasionally at dusk.
At our previous house, next to the woods, we had also wild turtles, garter snakes, a fox, a family of owls, several deer, moles in the lawn (grrr), and a few coyotes, all within a short distance of the house. I sort of applauded the coyotes because they helped keep the feral cats in check that were preying on the birds.
It is very depressing to realize that I have reached at least middle age: when someone asks me for a story about my wild life, instead of a tale of parties, drinking, and romance, I talk about birds, bunnies, and bats in the attic.
