When is a problem with pests & entry points urgent?
Treat a pests & entry points problem as urgent when it creates an immediate safety exposure, active damage, loss of an essential service in dangerous weather, or rapid worsening.
What this means
Pests & entry points covers rodents, insects, nests, damage, and openings. Relevant observations include Mouse droppings appeared, Ants keep entering, Buzzing is inside a wall, Wood shows insect damage, Animal is in the attic. The correct response depends on age, design, climate, usage, installation, recent work, and the exact manufacturer instructions; these observations narrow next steps but do not prove a failed part.

- Move people away and use only a normal safe shutoff or disconnect when accessible.
- Call emergency services for immediate danger; otherwise contact the relevant qualified trade.
Stop and get help if
- Leave or isolate the area for fire, gas, carbon monoxide, electrical exposure, collapse, sewage, or rapidly spreading water.
- Get qualified assessment when a hidden, growing, recurring, or structural condition is suspected.
