How to Get Rid of Rats in Fresno Homes
Seeing a rat in your Fresno home can be alarming, but finding the cause of the problem is the first step toward getting rid of it. The most effective approach is to identify where rats are entering, remove food and shelter sources, trap active rats, and seal openings that allow them back inside.
Fresno County homes commonly encounter two types of rats: Norway rats and roof rats. Roof rats are especially important to consider around homes with trees, dense landscaping, attics, walls, and roofline access. Norway rats are more likely to stay close to the ground and may burrow around foundations, trash areas, or woodpiles.
Quick Answer: How Do You Get Rid of Rats in a Fresno Home?
To get rid of rats, seal entry points, set traps, and remove food and water sources while checking for signs of activity. Remove accessible food, water, fallen fruit, trash, and nesting areas. Use properly placed snap traps where rat activity is confirmed, then seal cracks and openings so new rats cannot enter.
The most important part is not simply removing the rat. The entry point and conditions that attracted the rat need to be addressed too. UC IPM identifies exclusion, removal of food and shelter, and trapping as key parts of rat management.
What Types of Rats Are Common in Fresno?
Roof Rats
They can move through elevated routes and may enter a home through openings around the roof, vents, eaves, soffits, utility lines, or other areas that are easy to overlook.
UC ANR’s Fresno Gardening Green specifically identifies roof rats as one of the most common rats found around Fresno County homes and neighborhoods.
Norway Rats
Inside buildings, they are more commonly found on lower floors or in ground level areas.
Because roof rats and Norway rats use different parts of a property, identifying their likely travel routes can make inspection and control more effective.

1. Gaps around plumbing and electrical lines
2. Attic and crawl space vents
3. Roofline openings
4. Eaves and soffits
5. Gaps around doors and windows
6. Garage door gaps

7 Steps to Get Rid of Rats in Your Fresno Home
1. Look for Signs of Rat Activity
Look for:
• Rat droppings in garages, kitchens, storage areas, attics, or near food
• Gnaw marks on food containers, wood, wiring, or other materials
• Scratching or movement sounds inside walls or ceilings
• Shredded material used for nesting
• Burrows around foundations or outdoor structures
• Gnawed fruit or nuts in the yard
• Rat pathways along fences, trees, utility lines, or other elevated surfaces
2. Remove Food Sources
Start by securing household and outdoor food sources. Keep garbage containers closed, clean up food spills, and store food in containers with tight fitting lids.
Pet food is another commonly overlooked source. UC ANR recommends putting out only enough food for pets to eat and bringing pet food indoors at night when practical.
Bird feeders can also attract rodents. If rats are active around your yard, look at where bird seed, pet food, compost, garbage, and fallen produce are being placed.
3. Clean Up Your Fresno Yard
Remove or reduce:
• Fallen fruit
• Dense piles of leaves and garden debris
• Unused woodpiles
• Excess vegetation
• Climbing plants against the building
• Unsecured trash
• Outdoor food sources
UC IPM recommends reducing dense vegetation and creating space between shrubs and buildings. It also recommends pruning tree limbs that are within three feet of a roof and removing climbing vegetation from buildings.
This can be particularly useful when dealing with roof rats because they are strong climbers and can use trees and vegetation as pathways toward a roof.
4. Find and Seal Entry Points
Inspect both the interior and exterior of the structure. Look at the roof, attic vents, eaves, soffits, foundation, garage, doors, windows, utility penetrations, and areas around pipes.
Use appropriate durable materials for sealing. UC IPM recommends materials such as steel wool, wire screen, or sheet metal and warns that rats can chew through several softer materials.
The CDC also recommends using metal, hardware cloth, cement, or other suitable materials for larger openings rather than relying only on soft materials.
5. Use Rat Traps Where Activity Is Confirmed
UC IPM describes snap traps as the safest, most effective, and most economical trapping method for rats. For Norway rats, traps are generally positioned close to walls, in dark corners, behind objects, or near areas with signs of activity. Roof rat traps may need to be placed in elevated locations where the animals travel.
Rats can be cautious around new objects. UC ANR notes that pre baiting traps before setting them can help overcome this behavior.
Keep traps away from children and pets and follow the manufacturer’s instructions.
6. Check the Attic and Roofline
Roof rats commonly use:
Trees → roofline → attic → wall or ceiling voids
Inside, inspect areas such as:
• Attic vents
• Eaves and soffits
• Roof penetrations
• Gaps around cables and pipes
• Damaged screens
• Areas where branches reach the roof
Roof rat exclusion often takes more effort because these rats are capable climbers and can enter through elevated openings.
7. Monitor After Removal
Continue checking the areas where you previously found droppings, gnaw marks, nesting material, or other signs.
The CDC recommends continuing trapping until there are no more signs of rodent activity. If new droppings, urine spots, or gnawing continue, the infestation may not be resolved.
How to Keep Rats From Coming Back
Remove what attracts rats.
Block how they enter.
Monitor for signs of new activity.
