Rats

Rats are rodents that can be found in and around residences.  While people do keep them as pets it is important to note that "wild" rodents aren't desirable around your home.  Not only can they inflict injury by biting, but they can be hosts to disease transmitting fleas, can contaminate surfaces of your home with their wastes, and can even have rabies. 

How to Prevent and Control Rats

Where Rats Commonly Enter and Infest Your Home

  • Broken or missing foundation vent screens.  Check vent screens behind masonry.

  • Outside crawl holes to foundations without screens or screens that do not fit tightly.

  • Eaves where two different roof planes meet (Bird nest) not closed leaving an access hole to the attic.

  • Spaces between roof shakes and tiles.

  • Attic vent screens damaged or left off during construction.

  • Spaces between roof jacks and vent pipes from stove vent fans.  Rats may enter kitchen cabinets through holes around vent pipes.

  • Bottom or side space of garage doors, front or back house doors or doors that are left open at night.

  • Rats enter houses from garages by the following means: between roof boards on shingle roofs, through holes where piping enters walls or foundations, or gnawing through sheet rock where rafters meet the common wall separating garage and house.

  • Holes in exterior walls of house of holes produced by "add ons"  where the new and old constructions meet

  • Brick chimneys which have settled away from house leaving a gap between roof and masonry.

Rat Proof:

  • holes around pipes with fix-all and screen
  • holes in vents with 1/4" hardware cloth
  • chimney, inside roof turbines, around ovens, sinks, and toilet vents with 1/4" hardware cloth
  • by replacing gapping thresholds and bottoms of garage doors
  • small openings at roof tile arches and eave overlaps with screen
  • around air conditioner, pool heaters and walls with steel wool.
