Know The Warning Signs Of Rodent Activity

There are many ways you might come across the warning signs of rat and mouse activity. Some are subtle. Some are not so subtle. Here's what you need to know in order to catch trouble early and take steps to keep these critters out.

Vehicle Damage

You might see damage to the insulation under the hood of your vehicle if you have a rodent problem brewing. Rats and mice collect soft materials for their nests, and one place that can get material from is hood insulation. If you see holes and damage, it is time to take action.

Black Droppings

Rats and mice leave their fecal matter in the areas they explore. You may find this material along your foundation, around utilities, inside a storage shed, or in secluded areas of your home. Rats and mice have similar droppings. They are blackish-brown and shiny when fresh. Rats leave droppings that are slightly larger than grains of rice, and mouse droppings are slightly smaller.

Smell of Urine

Rats and mice leave droplets of urine to create a map of their environment. They rely on their sense of smell, along with touch and hearing, to get around in the pitch dark. If you detect a scent of ammonia, you may have a rodent problem. The stronger the smell, the larger the rodent population.

Grease Marks

When rodents run along surfaces or crawl in and out of a hole, they can leave a black streak. The more rodent activity you have, the darker these smudges will appear. Look for them along your foundation, on baseboards in your home, and on top of pipes.


If you hear scratching or bumping in floors or walls, or thumping in your attic, you may have rats or mice. But they aren't the only animals that can get into Honolulu homes and create noises like these. You'll have to take the time to check for other signs of rodents in your attic or contact your PTH service team for an inspection.

Nesting Materials

When you take furniture or boxes out of storage and find soft, balled-up materials hidden inside, it's a rodent nest. You may also find a nest like this tucked in the recess of a structural cavity.

When you detect rat or mouse activity, what is the next step? Are these critters as bad as you've heard? Let's quickly look at the simple facts every Honolulu family should know about these two unique pests.

Don't Ignore A Rodent Problem

Mice are tiny rodents. They don't look like much of a threat. But it would be best if you didn't underestimate them. While they're small, the problems they can cause are quite big. The problems caused by rats are even bigger. Here's what you need to know:

  • Rodents chew on wires. A cut wire can spark a fire that can lead to significant property damage. A fire can also present a threat to everyone living in the structure.

  • Rodent holes allow other pests to enter your home. We have a few creepy critters in Honolulu that you definitely don't want inside your home.

  • Rodent holes can allow rainwater in, which can lead to wood rot and mold. Wood rot can attract a termite problem, and mold can create a health concern.

  • Rodent hair, saliva, and droppings are associated with disease transmission and have no business in your kitchen or pantry.

  • Rodents pick up microorganisms from trash cans and dumpsters. These invisible germs can cause stomach illness.

  • Rodents carry ticks and fleas, which are also associated with disease transmission to humans.

  • Both rats and mice breed quickly. It doesn't take long for a few rodents to turn into a big problem.

At the first sign of a problem (or even before), it is critical to take steps to deal with rats and mice effectively in Honolulu. Our recommendation for rodent control is to contact a professional. Let's take a look at why this is the case.

The Importance Of Professional Rodent Control Services

A common outcome of DIY rodent control is only partial success. While placing a trap and catching and removing a rodent or two; the infestation will still persist. The reason is that these animals have defensive abilities that protect them from danger. They inspect food sources, move quickly to avoid trap hammers, smell subtle scents that warn them of danger, and reproduce faster than traps can catch them. Professionals use professional equipment and strategies for comprehensive control.

Here are the steps PTH uses for rodent control:

  • We start by evaluating the property and the conditions of the infestation.

  • We identify the rodent species and target them appropriately.

  • We apply a mixture of control products to collect and remove rodents.

  • We monitor rodent activity and track the results of the control plan.

  • We alter the plan as necessary.

  • We apply exclusions to prevent continued entry.

  • When needed, we reduce exterior rodent populations for even greater control.

  • We apply rodent control until no rodent activity is detected indoors.

When you want professional pest control results, it pays to get professional assistance. If you're in Honolulu, contact your PTH service team to get rid of rodents. We use industry-leading methods to get results.

Five Easy Tips To Prevent Future Rodent Infestations

When it comes to dealing with rodents in Honolulu, prevention is key. We don't recommend attempting to get rid of a rodent problem on your own. Rats and mice are incredibly elusive and frustrating pests. But, if you don't currently have an issue, you can use the following rodent prevention tips to keep them out of your home.

Consider Food Sources

When a rat or mouse finds food in your yard, it may decide to stay and raise a family. You don't want that. Here are a few common food sources they target and what you can do:

  • Keep all trash in covered containers to keep rats and mice out. They don't have a problem eating old or spoiled foods.

  • Remove bird feeders or apply rodent guards to protect your feeders. Rats and mice eat seeds.

  • Pick up nuts or fruit that fall from trees in your yard and apply guards to prevent these animals from climbing your trees.

  • Apply screen material to guard fruits or vegetables from these animals.

Reduce Mobility

The last thing you need is for rats and mice to find a path to your home or a route to enter your home. Here's how they move about, and what you can do to deter them:

  • Rats and mice scurry along the ground and use yard clutter to help them navigate. If you have objects on the ground in your yard, consider stowing them indoors or removing them from your property to deter rats and mice.

  • Rats and mice can climb trees like squirrels do. It is important to cut branches near your roofline to keep rodents off your roof.

  • Rats and mice can scale pipes that run up the exterior of a home. Install rodent guards to stop them.

  • Rats and mice can run along power lines to get onto roofs. Put a guard on your lines to stop them in their tracks.

Remove Hiding Places

Rats and mice often scurry from hiding place to hiding place. They don't like being out in the open for long. Consider these potential hiding places in your yard and remove them.

  • Junk piles

  • Leaves and sticks

  • Campfire woodpiles

  • Scrap wood

  • Piles stones or bricks

Deter Nesting

When rats and mice find a concealed and protected space, they may decide to create a nest. Here are a few common nesting locations and what you can do to keep rodents out:

  • Apply hardware cloth around the base of all sheds on your property.

  • Apply fencing material around decks or patios.

  • Apply exclusion materials to seal any gaps or holes that lead into a crawl space under your home.

Apply Rodent-Proofing Materials

When rats and mice explore your exterior, you don't want them to find a way to enter your home. Here are a few common entry points and exclusion ideas:

  • Insert expanding foam into structural cavities, such as the void behind a joist.

  • Apply a caulking seal around windows and doors.

  • Replace weatherproofing material on exterior doors if you can see gaps.

  • Patch any gaps around plumbing.

If you roll up your sleeves and do the hard work of rodent prevention, you may never need to contact a professional for rodent control services. But, when these critters become pests, contact PTH for rodent control near you. We'll provide a comprehensive solution to removing these pests and keeping them out.
