When a wild animal or rodents have occupied an attic, crawl space or room, the contaminated surfaces and insulation harbor pathogens that remain virulent for several months. Cleaning with soap and water is insufficient and can even spread contaminants by aerosol. Professional decontamination eliminates the biological cause before it becomes a health problem.
Nova Extermination carries out certified decontamination on the South Shore, with professional equipment and biocides approved by Health Canada. License RBQ 5734 75930 01.
Areas concerned: flat roofs, balconies, ventilation ducts, engineering structures, commercial facades.
What pathogens are present and why it matters
Psittacosis (avian chlamydia), cryptococcosis (dry droppings fungus), histoplasmosis, parasites (lice, mites), acid degradation of materials by droppings.
These pathogens remain dangerous long after the animals have left: hantaviruses survive for several days in aerosols, leptospires for weeks in a humid environment, roundworm eggs for months. Particularly at risk: young children, the elderly, immunocompromised, pregnant women. Professional decontamination eliminates these vectors and certifies a return to a healthy environment.
Our decontamination protocol
P100 respiratory protection equipment, prior wetting of droppings (reduces the risk of aerosols), manual removal and vacuuming, biocidal disinfection, acid neutralisation of surfaces (droppings corrode), installation of anti-pigeon devices (spikes, nets, repellent gel).
Equipment used
- H13 class HEPA industrial vacuum cleaner (99.95 percent particle retention at 0.3 μm)
- Broad-spectrum biocides registered by Health Canada (Virkon, stabilized peroxide, rotating quaternary ammoniums)
- Full personal protective equipment (Tyvek suit, P100 half mask, nitrile gloves)
- Enzymatic odor neutralization (eliminates cause, not mask)
- Document camera for before/after photos (belayer)
Duration: 1 to 2 days depending on the surface.
Underwriting and Inspection
Here are the service variants we offer for this need:
- Spot decontamination (basement, shed, crawl space)
- Attic up to 600 sq. ft. with insulation setback
- Complete house after massive infestation
- Commercial decontamination (restaurant, warehouse)
What influences the quote
- Surface or volume to be treated
- Extent of the infestation or situation
- Accessibility of the areas concerned
- Response time requested (planned or emergency)
- Scope of the desired warranty
- Documentation required for insurer, notary or audit
The inspection is non-binding. We evaluate on site (or by phone as the case may be) and give you a written estimate adapted to your building before any work begins. No unpleasant surprises at the end.
Recommended next steps
Decontamination corrects the consequences of an infestation. To prevent it from happening again, several related services should be considered:
Home insurance coverage
Many home insurance policies cover decontamination when a loss is proven (animal infestation, biological damage). We make it easy to make the claim by providing:
- Detailed evaluation report with before/after photos
- Precise identification of target species and pathogens
- Detailed invoice with batches of biocides used
- Signed decontamination certificate
Practical advice: call your insurer BEFORE starting the work. Check your deductible and get a claim number. This speeds up the repayment.
Questions
Should the house be evacuated during decontamination?
For an intervention in an attic or crawl space, generally not. For decontamination in the living room, eviction of 4 to 8 hours after application of the biocide is recommended.
Will the smell really disappear?
Yes 95 percent of the time, as long as all contaminated insulation is removed. Enzyme treatment neutralizes the biological cause. If the odor persists after 7 days, we schedule a follow-up according to your warranty.
Do I have to replace all the insulation every time?
Not systematically. It depends on the volume and depth of the contamination. Our report clearly indicates whether replacement is required.
How long does it take between the call and the intervention?
5 business days on average. For urgent cases (unbearable smell, presence of children or animals at risk), 48 to 72 hours.
How long does the effect of disinfection last?
Indefinitely, as long as no new infestation contaminates the area. For this reason, we consistently recommend that entry points be closed after decontamination.

Frequently Asked Questions: Pigeon Decontamination
What is pigeon decontamination?
This service aims to remove the accumulation of pigeon droppings, nests and debris deposited on roofs, balconies, cornices and attics. Our technicians sanitize surfaces with approved products and can install anti-perching devices in Longueuil as well as in Brossard. It is used as soon as droppings accumulate and threaten the health of the premises.
Why is pigeon droppings a particular risk?
Pigeon droppings can transmit diseases such as histoplasmosis and cryptococcosis, as well as attract parasites such as mites and bird bugs. When dried, they release dangerous spores when swept away without protection. Our technicians therefore intervene with the required equipment according to CNESST standards.
Do you also remove nests and install pigeon control devices?
Yes, we remove nests and accumulated droppings, and then disinfect the affected surfaces. To prevent pigeons from returning, we can install picks, nets or other exclusion devices adapted to the building. This combined approach is more sustainable than a simple cleaning.
Does the droppings damage the structure of the building?
The acidity of pigeon droppings corrodes roofs, masonry and metal surfaces over time. They also clog drains and gutters, which can cause water infiltration. Rapid decontamination in Boucherville or Chambly limits this damage.
Do you offer a guarantee against the return of pigeons?
We aim for sustainable results evaluated on a case-by-case basis, without an absolute guarantee that there will be no pigeons at all. Effectiveness depends on the exclusion devices installed and the maintenance of the building, which remains the responsibility of the owner. Our technicians will advise you on the appropriate preventive measures.
What is the cost of pigeon droppings decontamination?
The price is established on the basis of an evaluation, depending on the surface area touched, the height of access and the volume of droppings and nests to be removed. An inspection on the South Shore or in Montérégie allows for a fair estimate. It is a paid service entrusted to certified technicians.
