Exclusion is the physical work of closing the openings pests use to reach the inside of a building. In Tinley Park, the common points are the garage threshold, gaps around utility lines in the foundation, the rim joist and damaged vent screens. Exclusion is done after the animals are removed, and Tinley Park Pest Control connects Cook County callers with a local technician.
Most pest problems in a Tinley Park house have a building cause as well as a pest cause. The spray or the trap deals with the animals that are inside, but the opening they used stays open until someone closes it. Exclusion is the step that stops the next group from arriving on the same route.
A typical detached house has many places where the structure meets the outside: the garage door bottom, the sill plate at the top of the foundation, the vent screens, the door sweeps, the window wells and the pipes that come through the wall. Each one is a potential entry, and most of them look sealed from a distance.
The work is done in a sequence. Animals are reduced first, then openings are closed with materials that resist chewing, prying and weather, and the result is checked. Scheduling the sealing before the animals are removed can close them inside, which is why the technician plans the order. Call (855) 974-4733 to arrange a survey of the entry points.
Do not use spray foam on a gap that carries a gas line or a flue without asking the technician first, because some products are not suitable near heat sources. Keep clear of attic insulation that has been disturbed by animals, and wear a mask when working in an attic. Report any gas smell immediately and call (855) 974-4733 once the area is safe.
The technician walks the exterior, then checks the matching point inside. A gap at the rim joist can be seen from the basement and felt from the outside, and the two views together show which openings matter and which are cosmetic.
Openings that carry rodents are sealed first, then those that let in insects, then the ones that only let in air. The ranking keeps the work focused on the entries that have been used rather than every gap on the house.
Metal mesh and hard filler close openings that rodents can chew, weatherstripping and a rubber sweep handle the garage door, and a foam or caulk product is used only where a pest cannot chew through it. Vent screens are replaced with a finer, sturdier mesh.
Work is sequenced after any animals have been removed, so nothing is sealed in. Ventilation is kept open where it is needed for a crawlspace or attic, and the technician makes sure that a seal does not block a moisture path.
Each closed opening is checked for a clean fit and the photographs or notes are kept. A repeat inspection after a few weeks shows whether a seal has worn or a new gap has opened since the work was done.
The garage threshold and door bottom, the gap where utility lines enter the foundation, the rim joist and the vent screens are the openings most often used by rodents. Insects tend to use the same gaps plus the window and door trim where it meets the siding.
The garage is usually the largest opening on a suburban house, and its bottom edge is the least likely to be sealed well. A door that has been installed for years may have a seal that has flattened, and a threshold that no longer meets the slab leaves a clear route under the door.
Utility lines that enter the foundation are the second main route. A pipe passes through a hole that was drilled larger than the pipe, and the space around it is rarely filled completely. Those gaps are checked from the basement and the outside together.
Caulk and foam alone are often not enough, because mice and rats can chew through them. Hard filler, metal mesh and weatherproof materials are used at openings that rodents may use, and caulk is reserved for small cracks that no animal can use.
A technician checks the material by trying to push a finger or a probe into the gap and by looking for chew marks in the filler. A seal that has been chewed through, even partly, is replaced with a harder material.
Foam is useful for filling the space around a pipe, but it is covered with a harder material on the outside so that the animal cannot reach it. The choice of materials is written into the visit notes.
Vents should be fitted with a finer mesh rather than closed, because attics and crawlspaces need airflow to manage moisture. The mesh keeps out rodents and insects while letting air move, and a closed vent can cause condensation and damage.
A torn or bent screen is the most common vent problem. A small tear is enough for a mouse, and a bent screen can let a rat in through the gap at its edge. The replacement mesh is chosen to be stiffer than the old screen.
Crawlspace vents are checked for moisture as well as openings. Sealing a vent that was providing airflow can trap humidity in the crawlspace, so the technician balances the sealing against the ventilation the space needs.
Sealing waits until the animals have been removed from the space it would close in. A nest inside a wall or an attic must be cleared first, or the animals will be trapped inside and forced to chew a new route out.
Sealing is also scheduled around the weather. Filler and foam need dry, moderate temperatures to cure properly, and a wet week can leave a seal that looks closed but does not hold. The technician plans the work for a dry window.
A repeat inspection checks the seals after a few weeks. A seal that has worn, cracked or shifted is adjusted, and the repeat visit is the point at which the work is confirmed.
A homeowner can check the garage threshold for daylight, watch the vent screens for tears, and look at the foundation where pipes enter the wall. Any new gap, staining or fresh droppings near an opening should be reported so that the seal can be checked.
A simple test is a flashlight in the garage with the lights off. Daylight under the door or along the threshold means the seal is not complete, and a note of where the light is seen helps the technician find the gap.
Check the foundation after heavy rain, when settling or soil movement can open a new line at the sill plate. A crack that is wider on one visit than the last is worth reporting.
The most common job on a suburban house with an attached or detached garage. The door bottom, the threshold, the side and top seals and the wall where the garage meets the house are checked, and the work often takes a single visit.
Covers the gaps where a gas or water line, an electrical conduit or a cable passes through the foundation or the rim joist. The work uses hard filler or metal mesh, and it is done from inside and outside where the layout allows.
Attic vents, soffit openings and the crawlspace vents are fitted with finer mesh that keeps out rodents and insects while still letting the space breathe. The check includes the roof edge and the soffit, where many entries are found.
Many Tinley Park houses were built with an attached or closely connected garage, and the wall between the garage and the house is a common route for pests that are moving through the structure. The sealing covers that wall as well as the outside door and threshold.
The detached houses built in the decades around the 1970s and 1980s have foundations where the sill plate and the rim joist meet a poured wall. Those joints move slightly with the seasons and are a common source of small gaps that open over time.
South-suburb lots that sit close to older fences, sheds or mature trees give rodents a route to the foundation that is easy to overlook. The exterior survey includes the ground at the base of the wall, where a burrow or a gap can start.

A typical house takes one visit to survey and seal the main openings, though larger houses or those with many utility penetrations may need two. The schedule depends on whether the animals have been removed first and on the weather for curing materials.
Some small gaps can be sealed with the right hard filler or weatherstripping. A larger gap, a gap at a gas line or a gap that a rodent has already chewed should be handled by a technician, who will choose a material that rodents cannot chew through.
It can, if the sealing is done before the animals are removed. A technician removes the animals first and then seals the openings, so the building is not closed around a group that has no way out.
It should not. Vents are fitted with a finer mesh rather than closed, and the technician keeps the airflow that the attic or crawlspace needs for moisture control.
A single sighting is a reason to check the entries, because one mouse is often the first of several. A survey can show whether there are open gaps that need sealing before the next group arrives.
The clearest check is a repeat inspection after a few weeks, looking for fresh droppings, rub marks and new chew marks. A seal that holds shows no new signs at the opening, and the technician can show you what was closed.
