Good Neighbors. Bad Roommates.Why Bats Belong Outside—Not in Your Attic

Most people know bats eat mosquitoes and other insects, making them an important part of our ecosystem. In fact, having bats flying around your property at dusk is usually a good thing.
But there’s a big difference between bats around your home and bats living inside your home.
When bats move into an attic, wall void, or other part of a structure, they can create problems over time.

What Makes Bats a Problem?

Unlike rodents, bats don’t chew wiring or destroy insulation to build nests. Instead, the biggest concerns are:
-Accumulating guano (droppings)
-Strong odors over time
-Staining around entry points
-Noise from an active colony
-Potential health concerns associated with guano   accumulation

The longer a colony remains, the more difficult cleanup can become.

Timing Matters

One of the most important things homeowners should know is that bat removal isn’t something that can always be done immediately.
Throughout much of the Inland Northwest, June, July, and August are maternity season.
During this time, young bats are not yet capable of flight. Sealing entry points or attempting exclusion during this period can trap flightless pups inside the structure, creating a much bigger problem for both the animals and the homeowner. Sometimes the best professional solution is to wait until the appropriate time of year, then perform the exclusion correctly.

Please Don’t DIY Bat Removal

This is one wildlife problem where good intentions often make things worse.
Trying to seal holes, install one-way doors, or remove bats without understanding their behavior can accidentally trap bats inside walls, attics, or even force them into your living space.
Bat work isn’t simply about getting them out—it’s about getting every bat out without harming them and making sure they can’t return.

What About Bat Houses?

Bat houses absolutely have value.
However, they’re often misunderstood.
Installing a bat house beside your home usually won’t convince an established colony to voluntarily move out of your attic.
Bat houses work best as an alternative roost after a professional exclusion has been completed, giving displaced bats another suitable place to live while keeping them out of your home.
Proper placement is also critical. Height, sun exposure, orientation, and surrounding habitat all influence whether bats will actually use a bat house.

What If Bats Are Just Hanging Around Outside?

Sometimes the issue isn’t an attic colony at all.
Bats may simply loaf beneath eaves, overhangs, or other sheltered parts of a structure.
In many cases, these situations can be managed using professional exclusion methods, specialized netting systems, or carefully selected deterrent products designed for these specific situations.
Choosing the right approach depends entirely on why the bats are using the structure in the first place.

Every Situation Is Different


The goal isn’t to eliminate bats.
It’s to keep them where they belong.
Bats are valuable wildlife and an important part of our environment. But when they move into your home, solving the problem requires careful planning, proper timing, and the right exclusion methods.
At Tahoma Specialty Pest Services, every bat situation begins with a thorough inspection so we can determine exactly what’s happening, when work can legally and ethically be performed, and the best long-term solution for both the homeowner and the bats.

What’s Digging Holes in Your Yard?

One of the most common questions I get is:
“I found a hole in my yard… what made it?”
The answer isn’t always obvious. Different animals leave different clues, and knowing what you’re looking at is the first step toward solving the problem correctly.
Here are some of the most common culprits we encounter around Spokane and the Inland Northwest.
🦫 Marmots
Marmots rarely dig a hole out in the middle of open ground. Instead, they usually take advantage of existing terrain.
Look for burrows:
Under rocks or boulder piles
Along concrete slabs
Near retaining walls
Under foundations or other heat-absorbing surfaces
If you see a large hole disappearing beneath riprap or a rock pile, there’s a good chance a marmot is involved.
🐿️ Ground Squirrels
Ground squirrels leave one of the easiest burrows to recognize.
Look for:
A hole about 3–5 inches across
A fan- or crescent-shaped mound of excavated dirt
Several active burrows in the same area
Open grassy fields, horse pastures, and agricultural land
For horse owners, these burrows can become a serious safety hazard.
🦡 Moles
People often blame moles for every hole they see, but moles actually leave very distinctive signs.
Look for:
A series of raised soil mounds
No obvious entrance hole in the mound
Shallow surface tunnels connecting the mounds
Moles spend most of their lives underground feeding on earthworms and insects.
🐭 Voles
Voles leave much smaller openings.
Look for:
A hole roughly the size of a 50-cent piece
Little or no loose soil around the entrance
Narrow runways through grass or vegetation
Unlike moles, voles often spend time above ground following these well-worn paths.
🐝 Bumble Bees & Yellowjackets
Not every hole belongs to a mammal.
Both bumble bees and yellowjackets commonly move into abandoned rodent burrows.
A few clues:
Little or no dirt around the entrance
A steady stream of insects flying in and out
Increased activity during warm afternoons
The insects didn’t dig the hole—they simply found a ready-made home.
🐝 Solitary Ground Bees
These beneficial pollinators create tiny pencil-sized holes in loose, sandy soil.
You’ll often notice:
Small volcano-shaped mounds of fine soil
Numerous individual holes spread across an area
Very little aggressive behavior toward people
These bees are important pollinators and are generally best left alone whenever possible.
🐍 Snakes
Snakes almost never dig their own burrows.
Instead, they use:
Abandoned rodent holes
Rock piles
Wood piles
Foundation voids
Other natural hiding places
Finding a snake near a hole doesn’t necessarily mean it made the hole.
Correct Identification Matters
Many burrows look similar at first glance, but treating the wrong animal wastes time, money, and often makes the problem worse.
Before choosing a treatment, it’s important to identify what’s actually living there.
At Tahoma Specialty Pest Services, inspection always comes first. Once we know what’s causing the problem, we can recommend the safest and most effective solution.
If you’ve discovered holes in your lawn, pasture, landscaping, or around your home and you’re not sure what’s responsible, we’re happy to help identify the culprit and develop a plan that actually solves the problem.

Some DIY Pest Control Works, Some Doesn’t.

One of the questions I’m asked most often is, “Can I handle this myself?”

The honest answer is… sometimes.

There are quite a few do-it-yourself pest control methods that genuinely work when they’re used correctly. There are also plenty that waste your time, and a few that can actually make the problem worse.

Here’s a look at some of the more common ones.

✅ DIY Methods That Actually Work

Borax Ant Baits

For some ant species, a properly prepared borax bait mixed with a food source can be effective. The workers carry the bait back to the colony, helping reduce the population over time.

The key is using the correct concentration. Too much borax can repel ants before they have a chance to share the bait with the rest of the colony.

Rubbing Alcohol for Bed Bugs

Rubbing alcohol kills bed bugs on contact.

If you see a bug while inspecting furniture or bedding, alcohol is one of the few household products I actually recommend using.

Just remember—it only kills what it directly touches. It won’t eliminate an infestation hiding in walls, furniture, or other inaccessible areas.

Diatomaceous Earth

Diatomaceous earth is a desiccant, meaning it damages an insect’s protective outer layer and causes it to dry out.

It absolutely works.

However, it’s often misused.

Because it’s a very fine powder, it becomes airborne easily. Breathing large amounts of dust isn’t good for people or animals, so avoid broadcasting it throughout living spaces.

When used, I recommend applying it only in enclosed voids, wall cavities, crawlspaces, or other locations where it won’t become airborne during normal activity.

It also has legitimate uses around poultry, where properly managed dust baths can help reduce certain external parasites.

Sticky Traps

Sticky traps are excellent monitoring tools for insects such as spiders, cockroaches, and crawling insects.

They help identify where activity is occurring and whether a treatment is working.

I do not recommend glue boards for rodent control. They are generally inhumane and often catch only juvenile mice while leaving the real problem unresolved.

🟡 Methods That Can Help… But Usually Aren’t Enough

Flea Foggers

Foggers can reduce adult flea populations and may provide temporary relief.

Unfortunately, they often fail to kill eggs hidden deep in carpet fibers or protected areas, which means the infestation usually returns unless additional treatment is performed.

Mothballs

Mothballs contain a strong fumigant and are designed for use in sealed containers to protect clothing from fabric pests.

People often try using them for mice, snakes, raccoons, and other wildlife.

While the odor can occasionally encourage an animal to leave a confined hiding place, they are not labeled for general wildlife control and should never be used throughout occupied living spaces.

❌ DIY Methods That Usually Don’t Work

Ultrasonic Pest Repellers

Despite their popularity, I have never found these devices to provide reliable pest control.

If they truly worked as advertised, the pest control industry would be using them everywhere.

Peppermint Oil, Dryer Sheets & Soap Bars

These are some of the most common recommendations you’ll find online.

While strong odors may temporarily discourage an animal or insect from using a particular spot, they rarely solve the underlying problem and almost never eliminate an infestation.

⚠️ DIY Methods That Can Make Things Worse

Aerosol Ant Sprays

This surprises many homeowners.

For certain species, particularly odorous house ants, spraying visible workers can cause the colony to split into multiple smaller colonies, making the infestation even harder to eliminate.

Sometimes spraying creates more ants—not fewer.

Consumer Bed Bug Sprays

Most over-the-counter bed bug products simply don’t eliminate established infestations.

Even worse, they can scatter bed bugs into new hiding places, making professional treatment more difficult later.

Bug Bombs for Bed Bugs

This is probably one of the biggest misconceptions in pest control.

People often assume bed bugs can be treated the same way as fleas because both feed on blood.

They can’t.

Bug bombs rarely reach where bed bugs actually hide and often cause them to disperse deeper into walls, furniture, and other protected areas.

My Philosophy on DIY Pest Control

I actually encourage homeowners to start with simple, practical solutions when they’re appropriate.

Good sanitation, sealing entry points, reducing moisture, trimming vegetation, and using the right DIY products can solve many small pest issues before they become major problems.

But when those methods stop working—or start making the problem worse—that’s usually a sign the issue has grown beyond what a do-it-yourself approach can solve.

That’s where experience, proper products, and a thorough inspection make all the difference.

At Tahoma Specialty Pest Services, my goal isn’t just to treat pests—it’s to solve the problem that’s allowing them to be there in the first place.
