What Is Rodent Control? Everything You Need to Know
Scratching in the ceiling at night. Droppings behind the rice cooker. A chewed corner on a bag of dog food. If that sounds familiar, you likely have rats or mice, and on Oahu you are far from alone. Our warm, humid weather, year-round food sources, and many older homes with gaps under the eaves make the island an easy place for rodents to settle in.
Rodent control means finding out where rats and mice are coming from, removing the ones already inside, and closing the openings they used so they don't come back. Traps are only one part of it. A proper job combines an inspection, cleanup of food and shelter, sealing of entry points, trapping or baiting, and follow-up checks.
Xtermco has been handling rats and mice for Oahu homes and businesses since 1961. This guide covers what rodent control involves, what you can do today, and what happens when you call a professional.
Rodent Control in Plain Terms
A good rodent control plan answers three questions: where the rodents are living, how they are getting in, and what is feeding them. Most programs follow the same basic steps:
- Inspection: Finding droppings, rub marks, nests, and the openings rodents use to get inside.
- Sanitation: Removing the food, water, and clutter that make a property attractive to rodents.
- Exclusion: Sealing gaps around pipes, vents, eaves, doors, and foundations so rodents can't get back in.
- Removal: Using traps and, where appropriate, secured bait stations to bring the population down.
- Monitoring: Checking back to confirm activity has stopped and to catch any new activity early.
If you skip any one of these steps, the problem usually comes back. Trapping without sealing just makes room for the next rat. Sealing without removal can trap rodents inside your walls.
Signs You Have Rats or Mice
Rodents are active mostly at night, so you often find what they leave behind before you see the animals. The Hawaii Department of Health lists these common signs:
- Droppings along walls, in cabinets, under sinks, or in the garage
- Gnawed food packaging, wood, plastic, or wiring
- Holes in window screens or around pipes where they enter walls
- Dark, greasy rub marks along the paths rodents travel
- A strong, lingering urine smell in closed spaces
- Scratching or running sounds in the ceiling or walls, usually after dark
If you're noticing more than one of these, the population is usually larger than it looks.
The Rodents Oahu Homes and Businesses Deal With
Knowing which rodent you have changes where you look and how you treat. These are the ones we see most often around Oahu.
Mice call for a different approach than rats. If your problem is mostly small droppings in the kitchen, our mouse control tips for Hawaii homes go into more detail.
Why Rodent Control Matters in Hawaii
Health
The Hawaii Department of Health says rodents can carry at least 10 types of disease, including leptospirosis, murine typhus, and salmonellosis. They also carry fleas, mites, and the parasite that causes rat lungworm disease.
- Leptospirosis: A bacterial disease that is most common in warm climates. Rats, mice, and mongooses can all carry it, and it spreads through their urine into soil and water.
- Rat lungworm disease: Rats carry the parasite, and snails and slugs pick it up from rat droppings. People are most often infected by eating raw or undercooked snails or slugs, or produce that hasn't been washed well. The state recommends washing all fruits and vegetables carefully.
- Food contamination: Droppings and urine on counters, pantry items, and stored goods can make people sick.
Property
Rats and mice chew constantly. They damage wiring, insulation, stored belongings, irrigation lines, and building materials. Nests in ceilings and walls hold moisture and odor. In a restaurant or food facility, a single sighting can also mean a failed inspection or a lost customer.
How Professional Rodent Control Works
When Xtermco provides rodent control service on Oahu, the visit follows a clear order so you know what is happening and why.
- Inspect the property. A technician checks inside and out for droppings, rub marks, nests, burrows, and entry points, including rooflines, vents, utility openings, and gaps under doors.
- Explain what we found. You'll hear which rodent you likely have, where it's getting in, and what is drawing it to the property.
- Remove active rodents. Traps and, where appropriate, tamper-resistant bait stations go where the activity is. We talk through placement around kids and pets before anything is set.
- Seal entry points. Gaps and openings are closed so new rodents can't move in once the current ones are gone.
- Follow up. Return visits confirm activity has stopped. For businesses and properties with ongoing rodent pressure, a recurring service plan keeps monitoring in place.
Traps, Bait, and Repellents: What Each One Does
If you're curious about sprays and plug-in devices, here is our honest take on which rodent repellents are worth trying. The Department of Health also notes that rodents caught in live traps and released outdoors can quickly find their way back.
What You Can Do Today
You don't have to wait for a technician to start making your home less inviting. These steps help right away:
- Store rice, cereal, pet food, and snacks in hard plastic, glass, or metal containers with tight lids.
- Keep trash in bins with lids that close, and take it out often.
- Pick up fallen fruit from mango, papaya, avocado, and banana trees.
- Trim branches, vines, and palm fronds away from the roof and walls.
- Clear stacked lumber, old boxes, and clutter where rodents can nest.
- Fix dripping faucets and leaks, and empty standing water.
- Look for gaps around pipes, vents, and doors, and seal them.

Cleaning Up After Rodents Safely
Don't sweep or vacuum dry droppings, because that can stir up dust carrying germs. Follow the CDC's approach instead:
- Air out closed spaces before you start.
- Wear rubber or plastic gloves.
- Spray droppings and urine with a disinfectant or bleach solution and let it soak.
- Wipe up with paper towels, bag the waste, and throw it away.
- Disinfect the area again, then wash your hands well after removing your gloves.
Rodent Control for Restaurants, Warehouses, and Other Businesses
Commercial properties have more doors, more deliveries, more food, and more places for rodents to hide. Restaurants, warehouses, offices, hotels, and schools usually need scheduled service rather than a one-time visit. That means regular inspections, monitoring stations, and records of what was found and done. Our commercial pest control programs are built around that kind of recurring service, and the same visit can cover roaches and ants too.
DIY or Call a Professional?
If you spotted a single mouse once, you may be able to handle it with a few traps and some sealing. It's time to call a professional when:
- You keep seeing fresh droppings after trapping
- You hear activity in the ceiling or walls
- You see rodents during the day, which often points to a larger population
- You find chewed wiring or damage in the attic
- You run a food business or rental property and can't risk a complaint
- You can't find how they're getting in
Frequently Asked Questions
How long does rodent control take?
It depends on the size of the population and how many entry points need sealing. Most jobs involve an initial visit and at least one follow-up to confirm activity has stopped. Your technician will tell you what to expect after the inspection.
Is rodent control safe around kids and pets?
Yes, when it's done carefully. Traps and bait stations are placed where children and pets can't reach them, and we go over placement with you before anything is set.
How much does rodent control cost on Oahu?
Every property is different, so we give you a price after we see the job. Estimates are free.
Why do rodents keep coming back after I trap them?
Usually the entry points are still open or food is still easy to reach. Trapping removes the rodents you have now. Sealing and cleanup stop the next ones.
Do you handle other pests on the same visit?
Yes. Xtermco also treats termites, roaches, ants, bed bugs, birds, fleas, silverfish, and centipedes, and offers ongoing service plans.
