What is rodent exclusion, and why does it cost more than baiting?
The short answer
Exclusion is finding and sealing every gap a rodent can use, with materials they cannot chew through, and repairing what they have damaged. It costs more than baiting because it is construction work rather than a service visit, and it is the only part of a rodent job that stops the problem returning.
What the work involves
- A full inspection of the roof line, soffits, vents, utility penetrations, foundation, garage door seals and crawl space.
- Sealing each opening with material appropriate to it — hardware cloth, sheet metal, mortar — rather than expanding foam, which mice chew straight through.
- Trapping down the population already inside, because sealing first leaves them in.
- Cleanup of droppings and contaminated insulation, with appropriate protective equipment.
- Checking wiring for gnaw damage, which is a genuine fire risk and is invisible from inside the house.
Why baiting alone is a subscription
A baited property with open entry points has a continuous supply of new rodents from outside, and the bait is doing exactly what it does: reducing a population that keeps being replenished. It is why a quarterly rodent plan can run for years on the same house. Ask any company quoting rodent work what their exclusion scope is, and if there is none, ask why.
A mouse needs a gap about the width of a pencil, and a rat about the size of a quarter. That is smaller than most people check for, which is why the inspection is the expensive part of the expertise.
Also asked
- Is steel wool enough to seal a hole?
- As a component, yes, and as the whole repair, no. Steel wool packed into a gap and sealed over is a common and reasonable technique; loose steel wool on its own works loose and rusts. Hardware cloth, sheet metal and mortar are what hold up over years.
