A Guide On How To Clean Out An Animal-Infested Crawl Space

Ever wondered how to clean animal contaminated crawl spaces? Many homeowners don’t exactly expect to find uninvited houseguests living in their crawl spaces when they go to check insulation or trace some wiring. Finding out that a family of rodents, squirrels, or even raccoons have taken up residence in a part of your home can be incredibly frustrating.

An animal-contaminated crawl space tends to mean clean-up is required, and you might need possible damage repairs. Leaving them there is also not an option since they could cause potential safety hazards.

It leads to the question of how to clean a crawl space with animal infestation. Read to know more!

What Is A Crawl Space Cleaning?

Not all houses have crawl spaces. Usually, they are found in homes that do not have a basement or lack a solid cement foundation. They are found beneath the home’s floor. The entrance of these small spaces is typically located outside the house and near the base.

These entrances are small, hence the ‘crawl’ in its name. You can find quite a bit inside crawl spaces, including ventilation, plumbing, gas hook-ups, and electrical components. These crawl spaces permit these necessary home elements to be accessible in case they need replacing.

There is a tendency for many homeowners to ignore their crawl spaces — at least not until something goes wrong. Unfortunately, that could lead to a myriad of issues.

If your house has a crawl space, it needs maintenance and cleaning, but it can be expensive. Professional crawl space cleaning involves hiring a professional to remove mould, debris, and pests. They also look for leaks, remove vapour barriers, use a special vacuum cleaner, and encapsulate the crawl space to reduce humidity.

How To Clean Your Animal-Infested Crawl Space?

Many homeowners don’t inspect the crawl space under their homes. Due to that negligence, unwelcome guests are given a chance to make a home out of it. This crawl space is a safe space for them, with lots of space and insulation for making a bed.  

If left unchecked for too long, your crawl space might end up severely damaged. So, if you find your crawl space contaminated with pests, what should you do?

Here is the general breakdown of how you can clean it:

Inspection

Grab a flashlight and start inspecting your crawl space. Start from the back and move along until you reach the way out. Don’t just look around — check the area.

Look for pests and animal droppings, check for foul odours and inspect the ductwork and wood beams. If you find a family of pests and freeloaders settling there, find a way to evict them.

Check the infested area and determine the level of damage. The outcome of your inspection can depend on several factors, including the type of species, how long they’ve been living there, and where their nesting area is.

Wear Protective Gear

Ensure you wear protective gear like long sleeves, a respirator mask, gloves, pants, a hat, and goggles. The area is not sanitized and could potentially harbour diseases in feces that can make you ill.

Wear protective gear when brushing areas like flat surfaces with feces or HVAC ducts.

Clear Out the Crawl Space

Empty the crawl space. Ensure that the only thing left is the air trunks and heating. Now that everything is out of the way, you should be able to see better where critters and pests are coming in and out of the crawl space.

You will need to seal these passages or holes out. Note that rats can squeeze into a hole the size of a nickel.

Disinfect the Space

After ridding the infestation and cleaning the area, disinfect the crawl space with microbial. Doing so can kill germs and even deodorize the space. Most importantly, disinfecting can break the pheromone throughout the area.

Call Professionals

If you deem the infestation out of control, it would be best to call in a professional. A professional crawl space cleaning service can come in and handle the cleaning and sanitizing of the space. Though, note that these services can be expensive.

Monitor It

Wait and monitor the crawl space over a few weeks to ensure that pests are sealed out and are not getting in. Search for evidence that they are not coming back.

You can replace the insulation if you want. You may also replace the moisture barrier on the ground.

What to Avoid When Cleaning A Crawl Space?

Knowing the “don’ts” in cleaning crawl spaces is also vital.

Don’t Install Many Vents

Too many vents in a crawl space invite more humidity. It creates more harm than good by making a moist environment where mould can live and thrive. Additionally, many vents give more opportunities for pests to find a way in.

Don’t Use Spray Foam

While foam insulation might help inside the house, it is a beast for crawl spaces. Using spray foams can trap moisture between the foam and the wall. When that happens, the moisture can seep through the foundation, effectively making a breeding ground for wood rot and mould.

Don’t Ignore the Drainage System

Water can collect within crawl spaces due to groundwater and rain. However, you shouldn’t let it sit or linger. Eliminate it immediately.

Don’t Use Fiberglass Insulation

Fibreglass is not suitable for handling moist environments. Installing them in your crawl space means they’ll rapidly absorb the moisture until it becomes an incubator for mould. As an alternative, consider foam board or polystyrene.

Conclusion

Crawl spaces are vital parts of the house that require maintenance so the air in your home remains healthy. It would be a nightmare if uninvited guests built nests and moved in. If there is an issue with your crawl space, work is necessary to restore it to its prime and original shape.
