Now that the weather is chilling down, a common problem for people (myself included) is the fall invasion of mice seeking warm places to hang out for the winter. This year has seen a lot more activity due to the heavy fall of acorns and other mast goodies (as reported in one of my earlier posts) which has led to a population boom. Already I have caught six mice and can still hear activity inside the walls or up in the ceilings. As this is an old house, there are plenty of spaces for them to sneak into and it’s not easy to find them or get at them to seal them up to keep the little pests out.

The enormous fecundity of mice is an adaptation to the unhappy fact that they are number one on the menu for a surprising number of creatures: cats, foxes, coyotes, weasels, hawks, owls, skunks, snakes, crows, blue jays, even occasionally herons, and oddly enough, squirrels. The mouse has out of necessity adopted a secretive life-style and it is possible to have mice in your house and not realize it. Of course if the population is large, a fair amount of scuffling ensues when they are moving in and begin competing for living space. There are a variety of signs that mice are sharing living space with you and it’s a good idea to learn what they are, if you are determined to make your home as mouse free as possible.

What kind of mice can you expect to find? There are a variety of species, but here in New Hampshire, the mostly commonly found in houses are the house mouse, white footed mouse, and deer mouse .

All are cause for concern as they can carry a variety of diseases such as Hanta virus,  salmonellosis,  Lyme Disease and a variety of less common diseases. So far bubonic plague, which is in the western US, has not made its way to the east coast (knock on wood…). While the likelihood of contracting some of these illnesses is fairly low, the risk is always there and needs to be kept in mind when dealing with these pests.

Which naturally brings us to the matter of getting rid of them. The search for a better mousetrap seems unending. Best avoided are the poisoned baits for mice. While they may get rid of the mice, it’s the kind of gift that keeps on giving as any predator (including the neighborhood cat) are likely to ingest these toxins themselves if they happen to catch and eat these mice before the mouse has been killed by the poison. I did try using poison bait once a very long time ago, but found that the mice often rather than immediately eating the bait would take and store it in various places, such as my clothing drawers, which I definitely did not appreciate. Also there’s a good chance the little creatures will expire in an inconvenient place (which of course you will not be able to reach) and create an unpleasant reek.

Glue boards and traps catch the mice but do not kill them. That apparently is left up to you. If you don’t mind bludgeoning mice to death, be my guest but don’t expect me to invite you to any parties. If you are too chicken to kill them, the alternative to let them die of thirst and starvation and… yeah I thought so. I guess there is a way to get them off the strip without killing them but it’s a bit of an operation that’s stressful for both the mouse and you. So unless you enjoy being exposed to mouse excreta ejected by panicky mice (and the diseases that go along with them) glue strips are definitely out.

Some people like to use humane traps which catch the mouse but do not kill it. They then can be taken away and dropped in an area far from your house, leaving you feeling virtuous but the mouse utterly terrified as it is now in a strange place it does not recognize. Now then, if a giant idiot grabbed you and dumped you off in a strange place, what’s the first thing you would do? Well, yeah, you’d tried to get home! Which is likely what the mouse will do. If you haven’t taken it far enough away, the mouse will eventually make its way back to your place. If not, it will probably get snagged by a predator somewhere along the way. The odds that the mouse will just shrug its shoulders and contentedly take up residence where you place it are pretty low. Even if it were inclined to do so, in all probability a mouse already resides there, and as they are very territorial, it will quickly give the intruder the heave-ho.

This leaves the old fashioned snap trap. The wooden ones made by Victor are still available along with a wide variety of plastic snap traps and electronic traps which zap the rodents. I have tried a good number of them as I have arthritis and find it impossible to set the wooden ones. Success varies quite a bit with a number of traps failing to trigger when the mouse comes along and blithely eats the bait. The single electronic trap I tried, killed one and only one mouse and never again caught anything. The Victor quick kill trap seems to work as well as any of them, provided you position it so the mouse has to come directly at it and not from the side.

I’ve read the various reviews people have given of the different traps available and get the impression success depends as much on luck and the ability of the user to follow instructions, as it does the trap itself. Of course there is one mouse trap that rarely fails and has yet to be improved on. It’s the one that likes to sit in your lap and purr. The only drawback to this one is that it will occasionally present one of its catches to you, sometimes still in wriggling condition. Oh, well….

Wednesday September 23rd was the first official day of fall. For those of us in denial about summer ending, the calendar is something we would like to turn to the wall but unfortunately nature is not one to coddle us. The nights are distinctly cooler now. Although the first frosts usually show up here in northern New Hampshire about the first week or two of September, they have been delayed allowing us to play ‘let’s pretend’ a bit longer. But now the first frost advisories have been posted and the leaves are inexorably if slowly beginning to change color.

Last Wednesday I went for my morning walk, a regime I follow in order to put off joining the wheeled walker brigade for as long as possible. The sound of flapping caught my attention and saw what at first I took to be two crows diving around the tree branches, the first crow making an odd rattling noise that apparently indicates extreme terror. The reason became quickly apparent, for the second bird was not a crow at all but a hawk.

The crow did some pretty fancy aerial acrobatics, enough so he was able to elude his attacker by the skin of his beak, the hawk finally breaking off, apparently giving it up as a bad job. Though it flew off before I had a chance to memorize its markings, it was likely a broad-winged hawk. I don’t recall that it had any black bands on its tail so it was possibly a juvenile. Peterson’s Guide describes this species as being ‘crow-sized’, which sounds about right. Northern New Hampshire has a wide variety of hawk species both large and small, Coopers Hawk, Sharp-Shinned Hawk, Red Tailed Hawk, among others. This is likely a good year for them for as I mentioned in my previous post, this is a mast year with abundant acorns, pine cones and other fruit. I have already noticed an increase in the grey squirrel and chipmunk populations feasting on the nuts so there is plenty for the hawks to eat. Many of them will fly south for the winter but a few hardy souls will hang around and stick it out through the cold weather.

We are finally getting some badly needed rain.

The past few months have been unusually dry with local brooks starting to dry up and rivers being reduced to streams. But with the weather now beginning to shift, rain clouds have shown up with potentially heavy showers and the weather man has hinted we might even see some rain from Tropical Storm Joaquin by next week. Seems to be feast or famine these days.

Just prior to the rain showing up, white mushrooms starting popping up on my front lawn. I had watered the gardens with a sprinkler hose and as some of the moisture inevitably landed on the grass; the sudden bonanza of water likely triggered their appearance. I have no idea what species it is and as I am not a mushroom aficionado, have no interest in determining if it is edible or not. It is usually best to assume all are poisonous which for me takes the guesswork out of it. Those of you who are the adventurous types can make the determination. For anyone who samples one, natural selection will quickly weed out anyone who didn’t do their mushroom homework.

As for what the coming winter will be like, that depends on who you like to get your weather prognostications from. The Farmer’s Almanac is predicting another shivery winter for New England. However others are suggesting the El Nino currently building up over the Pacific may produce a milder winter than usual though everybody seems to hedging their bets. For those of you who like to watch for weather omens from Mother Nature and place great faith in the color pattern of woolly bears the disappointing truth is, that the coloration is genetically determined. I have seen varying patterns on different caterpillars in the same year so unless you want to assume some of them are trying to pull the wool over our eyes (sorry, couldn’t resist), you won’t find any certainty there either.

For now, let’s just enjoy the fall weather, with the accompanying show to be put on throughout October by the trees changing color, along with birds flocking together in preparation for migration, and all do our best in trying to ignore those nasty little white flakes starting to wing their way out of the sky to whiten the mountaintops of northern New Hampshire.

With autumn fast approaching, it’s time to start winding down the garden and cleaning up in preparation for the coming winter. One thing I couldn’t help noticing over the past month is the enormous number of acorns being produced by the local oak trees. There have been some days where I have heard a near constant sound of nuts falling. My driveway is littered with crushed acorns (where I ran over them while backing out the car), half eaten nuts and the small brown caps, called a cupule, that usually are discarded by the squirrels. The lawn mower makes an interesting noise when it tries to grind up any that it comes across while I am mowing. I can anticipate finding tiny oak trees over the next few years in the flower garden, my raised beds and even in a few of the large flower pots that I leave dirt in rather than try to dump out.

This extravagant production on the part of the oak trees is referred to as masting. Mast is an old term referring to the fruit of forest trees. There is soft mast (such as berries, drupes, and rose hips) and hard mast (such as acorns, beech and hickory nuts). When one of these booms in fruit production occurs, it is usually called a ‘mast year’. In times past, farmers would turn loose their pigs to forage and fatten up on this windfall from nature. Peterson’s Field Guide for Eastern Forests suggests masting is likely an adaptation to escape seed predators. Trees usually will alternate high production of nuts and berries with poor years, waiting for the population of squirrels, chipmunks and other fruit thieves to drop, then producing a bonanza to ensure that at least some will have a chance to take root and give birth to the next generation of trees.

Regardless of whether it’s a good year or a bad one, animals depend heavily on these vital food sources to prepare themselves for winter when they will migrate, hibernate or rely on fat reserves to get themselves through the cold months. Providing a wide variety of hard and soft mast, if you have land available for it, is a good way to help promote biodiversity.

Humans (at least the modern day humans) do not rely as much on wild mast but instead produce their own ‘mast’ in the form of a wide assortment of domesticated crops. Right now in northern New Hampshire, it is apple picking season. Apple orchards are reporting a 14 percent increase in apple production this year helped by ideal growing conditions this summer, with good pollination and no late frosts. Apples are a type of domesticated pome fruit so a bumper crop of apples would not be referred to as a mast year. However, for anyone who loves apples and other fruits, the picayune botanical details are nowhere near as important as the flavor and freshness. I am partial to Paula Reds, and Macintoshes and prefer eating them out of hand. The local food coop provides a wide choice of locally grown products which spares me a great deal of driving time trying to hunt down local versions of my favorite foods. On Sunday, there is a farmer’s market in my home town which also provides a good assortment of local produce.

I also have several raised beds where I try out my hand at growing carrots, potatoes, peas, wax beans and a few other vegetables with varying degrees of success.

Animals have a very keen eye for our ‘mast’ production so it becomes a bit of an arms race to fend off hungry four legged neighbors long enough for us to get a chance to harvest all our hard work. Fences, chicken wire and predator scents in a bottle are all useful but have to be diligently maintained. Another possible method is providing alternatives for animals to turn to in the form of forest corridors and woodland preserves, helping protect our own food from being gobbled up (except by us, of course!). None of these strategies are perfect of course, but then no system is or ever will be. Ever since we first starting poking seeds into the ground in an effort to increase the supply of the foods we like to eat, a never ending battle has been waged with critters who discovered that foraging is a whole lot easier where humans live (and they plant such yummy stuff!). As long as the pillaging remains below a certain level, we have to accept that some of our ‘mast’ is going to wind up in someone else’s stomach and not waste energy pitching a hissy fit because one of our ‘perfect’ tomatoes or ears of corn has mysteriously vanished.

With the seemingly unending cornucopia of foodstuff being poured into our supermarkets by modern industry, it’s easy to forget (or never realize in the first place) that what nourishes us comes directly from nature and only from nature, not from a cardboard box or a microwave oven. Buying food grown locally or better yet, growing it yourself is an important antidote to the detachment fostered by prepackaged concoctions barely recognizable as food and requiring little or no preparation on our part. If you want to improve your sense of well-being, the earthy aroma of a new potato or sweet fragrance of a freshly picked ear of corn should tell you everything you need to know about what’s good to eat. No frozen dinner could ever do that. We are only as healthy as the soil our real food grows in. A mast year or a bumper crop of apples helps remind us that the earth has an enormous reservoir of vitality that will only continue as long as we support it by maintaining the land with careful farming techniques and ensuring land is always set aside for wildlife.

“Eating with the fullest pleasure – pleasure, that is, that does not depend on ignorance – is perhaps the profoundest enactment of our connection with the world. In this pleasure we experience our dependence and our gratitude, for we are living in a mystery, from creatures we did not make and powers we cannot comprehend.”
