Entry Sealing

Stink Bug Entry Sealing: what it covers

Quick answer

Entry sealing in Leominster closes the openings that overwintering stink bugs use to get into a house. UMass Extension says these insects overwinter in homes, sheds and similar buildings, so the sealing is planned for the roof line, the windows and the foundation before the cold months. Sealing is the lasting step; removal inside is the step that follows it.

Sealing is the step that changes the number of insects a house receives each year. A bug removed from an attic this autumn is gone; a gap left open at the eave lets the next one in. The sealing list is therefore the most important document a visit produces, and it is written before the first cold day.

The UMass account says the insects overwinter in homes, office buildings, sheds and warehouses, which means any building with an open route is a candidate. The sealing work in Leominster follows the route from the outside, where the gaps are found, and it closes them with materials that suit the surface and the weather.

Warning signs

Signs you need stink bug entry sealing

Work from a stable ladder on firm ground, with someone nearby. Keep clear of overhead lines and do not reach across a gap from an unsteady position. Wear a mask when cutting or sanding foam, and keep pets and children away from the work area while caulk or foam is applied.

  • A light showing through a gap at a window corner or a door threshold on a bright day
  • A draught moving a curtain or a loose sheet of paper near a window
  • A dark line of grime inside a window frame where insects have walked
  • A gap in caulk at the joint between a window and the siding
  • Open or torn soffit vents with no screen in place
  • A cable or pipe entering the house through a ragged hole with no collar
Our process

How our stink bug entry sealing visit works

  1. Walk the outside at the right height

    The technician checks the building from ground level and from a stable ladder, since some gaps are visible only from above, such as at the eave and the gable.

  2. Test each gap with light and touch

    A flashlight held behind a frame on the inside shows light through a gap, and a hand near a frame feels a draught. Both checks catch what the outside view misses.

  3. Seal in order

    Large openings come first, then joints, then fine cracks. Foam goes into deep openings, caulk onto surface joints, and metal over larger gaps. Each sealed point is marked on the plan.

  4. Fit screens and weatherstripping

    Vents are screened and worn door sweeps are replaced. These parts wear out, so the plan notes the date of fitting and when to check them.

  5. Check from inside on a bright day

    A final pass with the room dark and the window lit shows any gap still letting light through. Gaps left are added to the list, not left for the next autumn.

Where do overwintering insects get in?

They get in at the gaps the building has always had: the frames of windows and doors, the joints of siding, the soffit vents, the gable vents and the points where a cable, pipe or vent passes through the wall. Those are the places the sealing starts.

A window frame is a common route because it is made of several pieces that meet at corners and at the sill. Over the years the caulk shrinks or cracks at those corners, and a gap opens that is hard to see from a distance. The gap is often only a few millimetres, which is enough for a small insect.

The soffit and the gable are the second group. Where the soffit meets the wall there can be a joint that has moved with the seasons, and a vent without a fine screen is an open door. The technician checks each one, and the joints where the soffit meets the eave are marked.

Which materials suit each gap?

Caulk suits small joints, expanding foam suits deeper openings and metal suits larger gaps and vents. Screens and weatherstripping close the spaces that caulk cannot reach. Each is chosen to stand up to the weather.

Exterior caulk is tooled into the joint so it sits within it rather than on top. Foam suits a deeper opening such as the gap around a pipe through a rim joist. Exposed foam is trimmed and covered or painted, because it breaks down under sun and freezing.

Fine mesh is fitted to vents, and a metal cover is used for a larger opening at the eave. A door sweep closes the gap under an exterior door, which is often the largest gap in an older house. The technician names the material used for each point.

Why the outside walk comes before the inside

The outside walk finds the openings where the insects enter, and the inside check confirms which of them lets light or air through. Doing the outside first shows the entries, and doing the inside afterward shows what the outside missed.

A gap that is visible only from the outside is sealed from the outside. A gap that is visible only from inside, such as a space behind a radiator cover, is sealed from inside. The report records the side from which each seal was made.

The inside check is done on a bright day with the room dark, so a light through a gap is clear. A draught found with a hand near a frame is recorded in the same way as a light through a gap.

When is the work done?

The sealing is best finished before the autumn, when the insects begin to look for overwintering spots. The walk is booked in late summer so the materials can be fitted in mild weather and given time to set.

Caulk and foam set best in mild weather, so a late-summer booking gives the best result. A sealing job done after the first cold snap is still worth doing, but the materials set less well and the insects may already be inside.

A check after the first heavy storm and again in the spring looks for openings that have moved. The report records each check, so the next season begins from a known condition.

What can a homeowner do between visits?

Keep the window seals and door sweeps in good order, replace any torn vent screen as soon as it is noticed, and walk the outside once in the spring to look for new openings.

A homeowner who notices a draught at a window in the cold months can mark the spot and tell the technician at the next visit. A draught is a sign of a gap, and the gap is the thing to seal.

The vents should be checked for torn or missing screens each spring, because the winter can damage them. A replaced screen is a small cost against the number of insects it keeps out.

What the sealing list should record

The sealing list records each opening by side, height, position and material, and whether it has been sealed. An opening that could not be reached is marked as such and given a date for the next check.

A list in this form lets the homeowner see the state of the house at a glance, and it lets the next technician find each opening without searching. The list is updated at each visit and kept in the house file.

An opening that has been sealed and then opened again is noted with the date, because it shows the seal has failed under weather or movement, and a stronger fixing or a different material is recommended.

Worcester County

Why stink bug entry sealing is different in North Central Massachusetts

UMass names homes, office buildings, sheds and warehouses as overwintering sites, and the sealing list for a Leominster house follows the walk: the sheltered upper spaces first, then the outer shell.

The Nashua River and the Wachusett Reservoir shore are part of the local geography. The sources do not link either to the insects, and the sealing reads the house on the day.

Houses across Worcester County built in different periods have different window and soffit joints, and the sealing list is written for the house in front of the technician.

FAQ

Stink Bug Entry Sealing FAQs

Can I seal the gaps myself?

Many gaps can be sealed by a homeowner with the right caulk and a steady hand. Higher gaps and work near electrical or gas lines are better left to a professional.

How long does sealing last?

It depends on the material and the exposure. Exterior caulk and foam weather with sun and cold, so the plan notes when each point should be checked, and a yearly look is the usual minimum.

Will sealing stop every insect?

No. It reduces the routes in, and so the number that get inside. Insects already inside must be removed, and a few may still find a gap nobody has found yet.

Is sealing covered by a warranty?

This site offers no warranty on any work. The technician explains what was sealed and what the plan recommends next, and the work is between the homeowner and the company that performs it.
