Why trapping alone leaves the door open.
Clearing animals from a house without closing the way in resets the clock. New rodents arrive by the same route, drawn by the same warmth and food. Exclusion ends that cycle by turning the building into a surface rodents cannot enter.
It is also the quietest part of the job. Sealing involves measuring, cutting mesh and fixing it in place, usually without any smell or mess.
Where the gaps usually are.
| Spot. | Typical material. | Why it works. |
|---|---|---|
| Roof edge and soffit joints. | Metal flashing under trim. | Teeth cannot bite through thin sheet metal. |
| Gable and roof vents. | Heavy mesh in a screwed frame. | Airflow stays open, animals stay out. |
| Dryer and bath exhausts. | Metal hood with screen. | Flaps and plastic louvers get chewed or stuck open. |
| Utility penetrations. | Steel collar plus sealant. | Closes the ring around a pipe or cable. |
| Garage door edges. | Replacement seal, threshold repair. | Removes the daylight strip animals follow. |
This table shows common weak points only. Your house may have others, and the survey finds them.
Materials we trust and ones we do not.
- Trusted: hardware cloth, stainless or galvanized mesh, metal flashing, mortar and masonry sealant.
- Used only with backup: expanding foam, silicone caulk, rubber gaskets.
- Avoided alone: steel wool, plastic mesh, cardboard backing, duct tape.
Teeth wear down against steel but adapt to soft materials quickly. That is why anything chewable needs metal behind it.
Coastal conditions and materials.
Salt in the air can corrode thin or untreated metal over time. We cannot measure that on your street, but we can choose coated or stainless products where a repair will be exposed. Ask during the survey if a particular opening sits in a spot that gets wet or windy.
Planning the order of work.
A typical sequence starts with the largest openings and ends with the smallest. Exits are left open where an animal may still be inside, then closed once devices show the structure is clear. The trapping page explains that timing.
Testing the repair.
The recheck includes pressing on each seal by hand and looking for new chewing. Where a seal has been scratched or bent, the technician reinforces it. A record of the repairs stays with your estimate, so future visits know which openings were closed and with what.
Handling waste without raising dust.
Once rodent waste dries it flakes into fine grit, which is why careful cleaning is wet and unhurried. The advice below mirrors public health guidance, whether or not you ever hire us.
- Dried pellets and nests crumble into dust, so keep the broom and shop vacuum away from them.
- Air trapped in attics, garages and sheds needs a cross-breeze before anyone enters.
- Keep a spare pair nearby so no pellet ever meets bare skin.
- After the wait, lift the soaked mess in a single sweep with a paper towel.
- Gather towels, gloves and waste in one bag, place it inside a second, and only then carry it out.
- Finish by scrubbing your hands with soap and warm water for twenty seconds or more.
