Mobile and Manufactured Home Treatment
Skirting, utility runs and under-home access create entry points specific to this type of construction.

Gaps or damage in skirting around the base of a mobile or manufactured home create a direct path for outdoor species into the crawlspace below.
Utility Runs and Plumbing Connections
Utility and plumbing connections entering from underneath the home are common access points worth checking as part of an inspection.
How This Construction Differs From a Standard Slab Home
Raised construction over a crawlspace, rather than a slab foundation, changes where the relevant entry points and moisture sources typically are.
Moisture Under the Home
The space under a manufactured home stays shaded and often damp in Florida, especially after summer storms. Standing water, a torn vapor barrier, or a dripping supply line underneath creates the kind of dark, humid harborage outdoor cockroaches look for, right next to the floor above.
- Pooling water after rain along the skirting line
- Torn or missing ground cover or vapor barrier
- Condensation from AC lines draining under the home
- Slow drips at plumbing connections through the floor
Floor Penetrations Inside the Home
Where plumbing and ductwork pass through the floor, under the kitchen sink, behind the toilet, under the water heater closet, openings are often larger than they need to be. These gaps connect the living space directly to the crawlspace, and they're usually simple to seal once found.
Check under the kitchen sink, behind the washer and dryer, around the water heater and at the base of the toilet. Expanding foam or caulk closes most of these openings, and escutcheon plates can cover larger ones around pipes for a neater finish.
Manufactured Home vs. Slab Home: Where to Look
| Factor | Manufactured / mobile home | Slab-on-grade home |
|---|---|---|
| Main entry route | Skirting gaps into the under-home space | Door sweeps, weep holes, utility penetrations |
| Moisture source | Crawlspace dampness, AC drainage | Irrigation, mulch beds, slab-edge leaks |
| Inside hotspots | Floor penetrations under sinks and water heater | Wall voids, garage, sliding doors |
| Access for inspection | Often requires getting under the home | Perimeter and attic access |
Communities and Park Rules
In a manufactured home community, lot owners and park management may have different responsibilities for skirting, landscaping and shared structures. If activity seems to be coming from a neighboring lot or a shared building, it's worth mentioning to management, treating one home in isolation has limits when the source is next door.
Some communities schedule periodic exterior pest service for all lots or common buildings. Asking management whether that's in place, and when it's scheduled, helps you time any work on your own home so the two efforts support each other rather than overlap.
It's also worth mentioning shared structures like clubhouses, laundry buildings and dumpster enclosures, since they can sustain activity that spreads to nearby homes.
Which Species Show Up in Manufactured Homes
Manufactured homes in Florida see the same species as site-built homes, but the balance often tilts toward outdoor roaches because of the crawlspace underneath. American cockroaches, smokybrowns and Florida woods roaches can shelter under the home and move up through gaps in the floor. German cockroaches still show up too, usually carried in on belongings, and once inside they behave the same way they would in any kitchen.
| Species | Where it usually comes from | Where you'll see it |
|---|---|---|
| American / palmetto bug | Under the home, drains, nearby sheds | Bathrooms, near the water heater, kitchen at night |
| Smokybrown | Trees near the roof, gutters, skirting | Near windows, upper cabinets, along exterior walls |
| Florida woods roach | Leaf litter and debris under or around the home | Near doors and in the living area floor |
| German | Carried in on boxes, appliances, bags | Kitchen and bathroom cabinets |
What an Under-Home Inspection Looks For
- Gaps, holes or separations in skirting, especially at corners and access panels
- Standing water or damp soil, particularly near AC drains and downspouts
- Torn or missing vapor barrier or belly wrap on the underside of the home
- Plumbing and duct penetrations through the floor with oversized openings
- Debris, stored items or wood stacked under the home
- Animal activity that may have torn skirting or insulation
The belly wrap, the fabric or board covering the underside of many manufactured homes, is worth special attention. When it tears, it exposes insulation and wall cavities that roaches can use as harborage right beneath the floor.
The Belly Wrap and Why It Matters
Most manufactured homes have a protective barrier on the underside, often called a belly wrap or bottom board, that encloses insulation and plumbing. Over time it can sag, tear or be cut for repairs and not resealed. Those openings give roaches and other pests access to a warm, protected space directly under the living area, with easy routes up through plumbing penetrations.
Repairing tears in the belly wrap is often a job for a manufactured home repair contractor, but pointing out damage during a pest inspection helps prioritize it. Sealing it back up closes one of the most significant harborage areas unique to this type of home.
An Owner's Seasonal Checklist
| When | What to check |
|---|---|
| Before rainy season | Skirting integrity; downspouts directing water away; AC drain line placement |
| After major storms | Skirting damage, standing water underneath, displaced vents |
| Fall | Clear leaf litter and debris from around and under the home |
| Every few months | Under sinks and around the water heater for leaks and gaps |
Older Mobile Homes
Older mobile homes, especially those built before modern HUD code updates, often have more gaps around windows, doors and floor penetrations, thinner skirting materials and belly wraps that have been patched many times. They can also have aluminum wiring access points and original plumbing with larger openings. None of that makes pest control impossible, but it usually means sealing work will have a bigger effect than in a newer home, and it's worth budgeting time for it.
When a Home Is Moved or Newly Set
Setting a manufactured home on a new lot is a good moment to prevent problems. Before the skirting goes on, it's easy to check the belly wrap, seal floor penetrations and make sure the ground underneath is graded to drain away from the home. Once skirting is installed, keep a vent or access panel you can open to check underneath periodically. Removing construction debris and leftover materials from under the home also removes harborage before it's used.
How Treatment Is Typically Approached
Treatment in a manufactured home usually works from the outside in. The specialist looks at the perimeter and skirting first, then under the home where access allows, and finally inside, particularly the kitchen, bathrooms and water heater closet where plumbing comes through the floor. Outdoor species are generally addressed with exclusion and exterior-focused treatment around the skirting and landscaping, while any German cockroach activity inside is handled with targeted indoor bait placements.
Because the under-home space is so closely connected to the living area, sealing floor penetrations from inside often has as much impact as anything done underneath. Expect recommendations covering both.

Frequently Asked Questions
Not inherently, the construction just has a different set of typical entry points, centered on skirting and under-home access, that a specialist accounts for.
Look for gaps, damage or areas where skirting has separated from the home. These are worth pointing out during an inspection.
Yes. The same considerations generally apply whether the home is on an individual lot or within a larger community.
Often, yes, depending on what the inspection finds, a specialist will explain what's needed for your home.
Rain saturates the ground under the home and can push outdoor species up through gaps in the skirting and floor.
Skirting still needs ventilation, the goal is closing damage and gaps, not blocking airflow, and a specialist can point out which openings matter.
Usually. Gaps around pipes and ducts through the floor can often be sealed during or after an inspection.
Mention it to park or community management, since the source may need to be addressed beyond your own home.
It's the barrier on the underside of the home, tears expose insulation and wall cavities that roaches can use as shelter.
They often have more gaps, so sealing work tends to have a bigger effect alongside any treatment.
