Burlington and the Champlain Valley

Seal the house before the first hard frost

Mice, flies, beetles and bugs come indoors in the same few weeks, by the same few gaps. In a house built before 1950 those gaps are in the stone, the sills and the roofline. We find them, close them and treat only where something is living.

Fall checklist

Seven places a Vermont house lets fall in

Walk the outside with this list before the leaves are down. Each number is a spot we check on a fall visit.

  1. 1

    Chimney top and flashing

    An open flue lets in squirrels and bats; a lifted flashing lets in wasps and flies. We look from the ground and from the attic side.

  2. 2

    Eaves and soffits

    Where the soffit meets the wall, boards shrink and leave a slot. A mouse needs a gap the width of a pencil, no more.

  3. 3

    Window and door frames

    Old sashes settle. Gaps at the sill and the casing let in flies and beetles first, and mice later.

  4. 4

    Where the porch roof meets the wall

    A joint that moves with every freeze. Insects follow the warm wall up to it.

  5. 5

    Pipes, cables and meters

    Every line through the wall has a ring of space around it. Steel mesh and mortar close it; foam alone doesn't.

  6. 6

    The foundation line

    Stone and brick open at the mortar joints, and shrubs hide the gaps. Keep plantings a hand's width off the wall.

  7. 7

    Porch steps and cellar doors

    Lattice, steps and cellar doors give mice a dark corner to study the house from.

A typical farmhouse of the valley; your house will have its own list.

Plates

The usual guests of an old Vermont house

Six plates from our notebook: what each one is, where it turns up and what we do about it.

  • Plate I

    House mouse

    Arrives from September. Scratching in the walls at night and a smell in the cellar come first; the way in is smaller than you'd guess.

    • Turns up: cellars, pantries, attic floors

    • We: find the way in, seal it, then trap if needed

  • Plate II

    Cluster fly

    A large, slow fly that gathers on sunny walls in fall and wakes in the attic on warm winter days.

    • Turns up: south walls, attic windows

    • We: seal the roofline, then treat what's inside

  • Plate III

    Boxelder and stink bugs

    Shield-shaped, they crowd the south wall in October and slip behind the siding to wait out the winter.

    • Turns up: window frames, siding, curtains

    • We: close the frames, then treat the wall line

  • Plate IV

    Carpenter ant

    A large black ant that nests in wood kept damp by a leak, not in sound timber.

    • Turns up: sills, porch posts, around the chimney

    • We: find the nest, then show you the leak

  • Plate V

    Gray squirrel

    Loud in the attic at dawn. It gets in at a corner of the roofline or a loose vent.

    • Turns up: roofline, attic, soffit corners

    • We: seal the entries; live animals go to a licensed handler

  • Plate VI

    Lady beetle

    Orange and round, in thousands on one sunny window frame in October and November.

    • Turns up: sunny frames, attic and upper rooms

    • We: seal the frame, vacuum, treat the edges

Calendar

The weeks that matter

Most of the fall list falls between mid-September and the first hard freeze. The bars show when each guest is most likely to be seen.

  • House mice

    Sep to Mar

  • Cluster flies

    Sep to Oct, Feb to Mar

  • Boxelder and stink bugs

    Sep to Oct

  • Lady beetles

    Oct to Nov

  • Squirrels in the attic

    Sep to Nov

  • Carpenter ants

    Apr to Jul

  • Paper wasps

    Jun to Sep

Timing follows the weather. A warm October stretches every bar.

How a visit goes

We start at the stone

A house built before 1950 usually has a fieldstone or brick foundation, a cellar with a dirt corner and walls that run open from the cellar to the attic. We begin outside at the foundation, then go down, then up.

A fall visit, in order

  • Walk the outside with a flashlight and an inspection mirror

  • Check the cellar and any crawlspace

  • Go into the attic on boards, with a headlamp

  • Close the gaps with steel mesh, metal flashing and mortar

  • Treat only where there is something to treat

  • Leave a written report that names each place we sealed

Before you call

What you can seal yourself, and what to leave to us

Some gaps are an afternoon's work. Others are hard to see, or hard to reach.

After the fall visit

What customers told us

“They found the gap under the porch step in the first twenty minutes. The report had a photo of it, and another of the mesh they put in.”

Polly H.Farmhouse owner

“The cellar was the problem, not the kitchen. Lea showed me where, and nothing was sprayed until it made sense.”

Fred S.Duplex owner

“I wanted to know what was in the walls before the snow. The checklist was on the refrigerator by the time they left.”

Lynette B.Homeowner

Where we go

Burlington and the valley towns around it

Most of our visits are in the Old North End, the Hill Section and the South End, and in the farmhouses of the valley towns around them.

  • Franklin County: Fairfax
  • Washington County: Waterbury
  • Addison County: Monkton, Ferrisburgh, Bristol

We don't work north of Fairfax, east of Waterbury or across the lake in New York.

Before you call

Questions we hear in September

How much does it cost?

It depends on the size of the house, how many ways in we find and how many visits it needs. What drives the price is on the how pricing works page, and we write the number down before any work starts.

When should I book the fall visit?

Early September through October is best, before the first hard freeze sends mice and flies looking for a way in. We book in the order the calls come in. If you have already heard scratching, say so when you call.

Is it safe for kids and pets?

Our applicators are licensed and follow the label on everything they use. We tell you where to keep children and pets away, and for how long, and we send the product list if you ask. Much of the fall work is sealing, which uses no product at all.

Do I need to be home?

For the first visit, yes if you can. We walk the house with you and show you each gap. After that we need access to the cellar and the attic.

Do you take on bats and squirrels?

We seal the ways in. For live animals in the attic we follow the state's wildlife rules and send you to a licensed handler. Bats are protected, and can't be shut out in summer.

What if the pests come back?

Call us. We come back, look at how they got in and write it down. Whether the return visit is covered depends on your plan, and the terms are in the written estimate.
