Once the exterminators leave, the job isn’t quite over. While exterminations may rid your home of pests, they still leave behind pest waste and other chemical residues. Fortunately, post-extermination cleaning helps remediate your home. From hidden pest waste to lingering extermination chemicals, there’s no shortage of reasons why post-infestation clean up is just as important as removing the pests themselves. 


In this short blog with Grimebusters, we’ll explore a few reasons why after-extermination infestation clean-up is essential. Let’s dive in below. 

#1: Easier Selling or Renting

Did you know that approximately 10% to 15% of home buyers will back out of a deal after their inspection? In many cases, evidence of pest infestations is one of the most common reasons for this happening. From bird nests to cockroaches and other insects, evidence of these pests can deter potential buyers from taking on the risk—even if an extermination has already been completed.  


This happens often in estate homes, especially when no one is living there to notice signs of pests. Fortunately, a professional post-infestation cleaning can help protect your property. Professional infestation cleaning helps ensure your property is safe and fully habitable for renters and buyers. 

#2: Remove Pest Waste

Long after pests are exterminated, droppings, urine, nesting materials, and other contaminants may remain. These signs of pest waste pose a significant risk to human health and can ultimately lead to a range of health issues. For example, although raw chicken is what many think of when they hear the word ‘salmonella’, the risk may be closer than you think. Mice waste found in homes, including droppings and urine, can contain diseases such as Salmonella and hantavirus. 


Waste from rodents, birds, and insects risks:

  • Diseases 
  • Parasites
  • Allergic reactions
  • Lower air quality 


Pest waste is biohazardous and should not be handled without proper tools and protection. At Grimebusters, we utilize industrial-grade equipment, including Tyvek suits and respiratory masks, to prevent contamination. 

#3: Proper Remediation of Chemicals 

The post-care process after an extermination will differ significantly depending on the specific pest. Many treatments have specific cleaning instructions to avoid undoing their effects. Some pests, such as bed bugs, require an especially meticulous cleaning approach after treatment. To effectively exterminate these pests, they must come into contact with the treatment. As a result, it’s essential to remain aware of the treatment location and avoid accidentally removing it. 


When you partner with an infestation remediation specialist like Grimebusters, we understand that maintenance is just as important as the extermination itself. We utilize the necessary gear, equipment, and processes to remediate your space as thoroughly as possible, minimizing disruptions to the treatment. 

#4: Proper Removal of Odours

Pest waste often creates lasting, hazardous odours. For example, mouse urine in particular develops a distinct ammonia-like smell over time. This happens as bacteria eventually break down mouse urea into ammonia. This ammonia smell is hazardous to humans and has the potential to cause throat irritation, eye redness, asthma symptoms, and other health issues.


Additionally, this ammonia smell often lingers in carpets, walls, and other surfaces. As a result, mouse urine may sometimes require heavy-duty remediation measures in order to rectify the situation.
