When Are the Bat Control “Blackout Dates” in Iowa?
In Iowa, bat control blackout dates span the summer maternity season from late spring through mid-August (peaking in June and July). During this critical window, state wildlife guidelines restrict colony exclusion to prevent flightless pups from becoming trapped inside attics and wall voids.
Outside of the summer pup-rearing season, exclusion activities depend heavily on ambient outdoor temperatures and bat biology. While Iowa does not enforce a statutory winter blackout, performing exclusions during sub-freezing months is ineffective; bats enter a state of torpor and will not fly out through one-way exclusion valves. For complete and humane colony clearance, exclusion valves require sustained evening temperatures consistently above 50°F to ensure all bats emerge to feed.
Regardless of the time of year, our wildlife specialists conduct thorough property inspections year-round—locating access points, sealing secondary vulnerabilities, and mapping out a compliant exclusion timeline so your home is ready the moment conditions allow.
Common Bats in Iowa
- Little Brown Bats: Little brown bats are small, roughly 3–3.5 inches in length with a wingspan of 8.5–10.5 inches. Their fur is short and glossy, either ashen in color or slightly rust-hued. Little brown bat populations have suffered dramatic declines due to White-nose Syndrome, leading to special state-level conservation protections and pending federal review. Because of their protected status, DIY eradication is strictly off-limits.
- Big Brown Bats: Considerably hardier than other native species, big brown bats have an average body length of 4.5 inches and a wingspan exceeding 12 inches. Their fur is typically a darker, muddier brown. Their adaptability to human-made structures and tolerance for cooler temperatures make them the most widespread bat species encountered across Iowa’s urban, suburban, and rural properties.

If You Find Bats in Your Home, Should You Worry?
An unmanaged indoor bat colony presents immediate structural, biological, and legal liabilities that escalate the longer the roost remains undisturbed. Leaving bats unaddressed compounds four primary hazards:
- Rabies: Rabies is a potentially fatal disease that affects mammals, including bats. While most bats do not carry rabies, it’s challenging to determine if a bat is infected just by looking at it. Bites or scratches from bats should be taken seriously, and immediate medical attention should be sought to rule out any risk of rabies transmission.
- Histoplasmosis: Histoplasmosis is a fungal infection caused by breathing in spores present in bat droppings (guano). When bat guano accumulates in attics, crawl spaces, or other areas, it can release spores into the air. Inhaling these spores can lead to respiratory issues, especially in individuals with weakened immune systems.
- Structural Damage: Bats often seek refuge in attics, wall voids, and chimneys, potentially causing structural damage to your property. Their urine and droppings can corrode materials and stain ceilings, walls, and insulation. Over time, this can lead to costly repairs and compromised structural integrity.
- Noise and Odor: Bats are nocturnal creatures and can be noisy during their activity periods, which can disturb your sleep and peace of mind. Moreover, their droppings emit a strong, unpleasant odor that permeates the affected areas and can be difficult to eliminate without professional intervention.
While bats play an essential role in our ecosystem, they often become a dangerous nuisance when they invade your home. A bat infestation in your home poses a significant risk to you and your family due to their potential to transmit diseases.
Our Bat Control Process
Because bats are protected by wildlife laws, traditional extermination and poison-based methods cannot be used. Springer provides 100% humane, legal, and effective bat exclusion services. Our trained wildlife specialists identify entry points around your roofline and install specialized one-way exclusion devices that allow bats to leave safely without returning.
Once the bats have exited, we permanently seal all entry gaps with heavy-duty materials, sanitize contaminated areas, and offer full Attic Insulation Restoration to fix guano damage—all backed by our Renewable Wildlife Warranty.
1. Comprehensive Property Inspection
- Entry Point Identification: Inspection of high-access areas like rooflines, soffits, fascia boards, ridge vents, gables, and chimney flashing.
- Species & Activity Assessment: Identifying bat activity (primarily Little Brown Bats and Big Brown Bats) and locating active roosting locations in attics, wall voids, or belfries.
2. Humane Bat Exclusion (No Harm / No Chemicals)
- One-Way Exclusion Devices: Installation of specialized one-way valves or netting over primary entry points. This allows bats to exit freely at dusk to feed, but prevents them from flying back inside.
- Regulatory Compliance: Adherence to state and federal wildlife regulations (including Iowa DNR guidelines regarding maternity season protection) to ensure humane, legal handling.
3. Full Structural Sealing & Proofing
- Secondary Gap Sealing: Professionally seal all secondary gaps, cracks, and potential entry points using heavy-duty, weather-resistant materials (e.g., galvanized wire mesh, silicone sealants, metal flashing).
- Permanent Exclusion: Ensure bats cannot find a new opening once the main entry is fitted with exclusion valves.
4. Guano Cleanup & Attic Restoration
- Sanitation & Decontamination: Removal of hazardous bat guano and urine deposits to eliminate ammonia odors and prevent histoplasmosis health risks.
- Insulation Repair/Replacement: Bio-hazard cleanup paired with Springer’s Attic Insulation Services to restore damaged or contaminated insulation, improving energy efficiency and air quality.
5. Renewable Wildlife Warranty
- Long-Term Protection: Backup through Springer’s Renewable Wildlife Warranty to guarantee entry points remain sealed and secure against future invasions.
What should I do immediately if a single bat flies into my living room or bedroom?
Isolate the bat immediately by closing all interior doors leading to other rooms, and open an exterior window or door to create a direct outdoor exit path. Turn on the room lights so you can easily track its flight path, keep pets and children out of the area, and never attempt to catch or swat it out of the air while in flight. If the bat lands, wear heavy leather work gloves—never bare hands or thin fabric—and place a plastic container over it, gently sliding a stiff piece of cardboard underneath before releasing it outdoors against a tree trunk or wall.
Important safety exception: If anyone was asleep in the room, or if an unattended infant, pet, or incapacitated person was present, do not release the bat. Contact local animal control or public health officials immediately so the bat can be tested for rabies to determine if post-exposure prophylaxis is required.
Does homeowner’s insurance typically cover bat removal, guano cleanup, and attic insulation restoration?
Standard homeowner’s policies usually exclude the actual bat removal and exclusion work, as wildlife removal is typically classified under ongoing property maintenance. However, coverage for the resulting biohazard cleanup, attic sanitization, and insulation replacement varies:
The “Rodent / Vermin” Exclusion: While insurers routinely deny pest damage under vermin clauses, bats are technically mammals (Chiroptera) rather than rodents. In cases where significant structural or insulation damage has occurred, some insurers approve attic restoration claims under comprehensive structural hazard provisions.
- The “Rodent / Vermin” Exclusion: While insurers routinely deny pest damage under vermin clauses, bats are technically mammals (Chiroptera) rather than rodents. In cases where significant structural or insulation damage has occurred, some insurers approve attic restoration claims under comprehensive structural hazard provisions.
- Biohazard Endorsements: If your policy includes hazardous waste or pollutant remediation endorsements, high-volume guano extraction and sanitization may be partially reimbursed. Request an itemized remediation estimate from your wildlife specialist to submit directly to your claims adjuster.
What are the legal penalties in Iowa for killing bats or using poison to eradicate an attic colony?
In Iowa, intentionally poisoning, trapping, or killing bats is illegal under state wildlife conservation statutes (Iowa Code Chapter 481A) and state animal protection laws.
- State Penalties: Unlawful taking or killing of non-game wildlife carries misdemeanor charges, with fines assessed per animal unlawfully killed or harmed.
- Pesticide Violations: There are no EPA-registered or state-approved chemical toxicants or poisons for bats. Applying illegal repellents, tracking powders, or fumigants inside an attic violates both the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and Iowa Department of Agriculture regulations, which can trigger steep civil and criminal fines.
- Federal Endangered Species Act: Little brown bats and northern long-eared bats have heightened federal and state protections. Harming maternity colonies or individual bats of protected species can result in federal wildlife violations.
What are "bat bugs," and will they bite humans or pets once the bats are excluded from the house?
Bat bugs (Cimex adjunctus) are small ectoparasites that measure roughly 4 to 7 millimeters in length—about the size of an apple seed—making them easily visible to the naked eye. Closely related and nearly identical in appearance to common bed bugs, they dwell directly inside bat roosts and feed primarily on bat blood.
- Do they bite humans and pets? Yes. Once the host bat colony is safely excluded and their primary blood source is gone, hungry bat bugs crawl out of attic floorboards, recessed lighting fixtures, wall voids, and electrical switch plates into living quarters searching for a host meal.
- Can they reproduce on humans? No. While their bites cause itchy, inflamed welts similar to bed bug bites, bat bugs cannot complete their reproductive life cycle on human or domestic pet blood alone. However, adult bat bugs can survive for several months without feeding. For this reason, professional bat exclusion should always be paired with a targeted residual insecticidal treatment in the attic and upper wall voids to eliminate residual bat bugs before they migrate downward into living areas.
Can bats chew through drywall, wood fascia, electrical wires, or metal screening like mice and rats do?
No, bats cannot chew through these materials. Unlike mice, rats, and squirrels, bats are insectivores and do not have gnawing incisors designed to chew through structural materials.
- Bats do not create their own entry holes; they exploit pre-existing construction gaps, settled trim, unsealed gable vents, or warped fascia boards as small as 3/8 of an inch.
- Bats will not chew electrical wiring or gnaw through ductwork. The danger to electrical components and building materials comes entirely from the chemical composition of their waste: concentrated uric acid and ammonia from accumulated guano corrode metal fasteners, degrade ceiling drywall, and create foul odors over time.
