What makes the university area different
It's rental-dense. Apartments, duplexes, fourplexes, and single-family houses split between roommates. That means most occupants can't authorize structural work, and most buildings have multiple households sharing one envelope.
Multi-unit buildings share everything that matters. Rodents travel wall cavities, plumbing chases, shared attics, and the space above dropped ceilings between units. A mouse in your kitchen may be nesting in the wall you share with a neighbor, or in an attic that runs the length of the building. Treating one unit is treating one room of a house.
Turnover is concentrated. Leases in a university area cluster hard around August and May, and that produces a predictable rodent pattern most people never connect. More on that below.
Occupancy is inconsistent. Units sit empty over the summer and over winter break. An empty unit is a rodent's ideal unit — no disturbance, no lights, no noise — and a population that establishes in a vacant apartment in July is a problem for whoever moves in during August.
Undeveloped land is close to the campus area, which keeps outdoor pressure up — cotton rats after any mowing or clearing, and house mice moving in with the first hard cold front.
The lease cycle is a rodent cycle
This is the genuinely useful, locally specific thing on this page.
Late May through July — the vacancy window. Units empty out. Trash accumulates at move-out, food gets left behind in cabinets, dumpsters overflow with everything students didn't want to move, and units sit undisturbed for weeks in the heat. This is when populations establish. Nobody is there to notice.
August — move-in. New tenants arrive to droppings in drawers they assume are old, or to a genuinely active population that's had two months of quiet. A significant share of "we just moved in and there are mice" calls are actually June's problem.
Also August: move-in itself brings cardboard — boxes stacked in units, in hallways, and by dumpsters. Cardboard is harborage and nesting material, and it's the single most overlooked attractant of the entire month.
October and November — the cold-front spike. The first hard Permian Basin front pushes rodents indoors, often within hours. This is when most sightings happen and when most calls come in. Seasonal calendar »
December and January — the break window. Units empty again for two to four weeks with the heat set low, no disturbance, and food left in cabinets. Same mechanism as summer, shorter.
May — move-out. The cycle restarts.
What to do with that: if you're moving in, check before you unpack — it's five minutes and it establishes what was there before you arrived, which matters if there's ever a deposit argument. If you manage the property, the vacancy windows are when the work should happen, not the day after a tenant complains.
If you rent: what you can actually do
Check the unit properly, and document it.
- Open every kitchen drawer and cabinet and look at the corners and the backs with a flashlight
- Under the sink — the gaps around the drain and supply lines are the most common interior entry in any kitchen, and in rentals they're almost never sealed
- Behind and under the fridge and stove
- The pantry floor and corners
- Closet floors, the laundry area, and behind the water heater
- Photograph anything you find, with the date. Do this before you unpack

Then tell your landlord or manager in writing. Not a text you'll lose, not a verbal mention to a maintenance tech — written, dated, with photos, and keep a copy. That written record is the single most useful thing a tenant has, and it costs nothing.
What you can do yourself without touching the building:
- Food into hard sealed containers — glass, metal, or heavy rigid plastic. Not bags, not the original box
- Nothing left on counters overnight, dishes washed, trash lidded and emptied
- Pet food and water bowls picked up at night
- Snap traps along walls and behind appliances, trigger side to the wall, far more of them than feels necessary — and out of reach if there's a pet in the unit. How to place them »
- Skip the poison, especially in an apartment. A poisoned rodent dies inside a shared wall, and that becomes a smell problem for you and your neighbors for weeks. Why »
- Break down and remove cardboard rather than stacking it
- Never dry-sweep or vacuum droppings — wet them down first, gloves on. Cleanup »
What you probably shouldn't pay for yourself: sealing the building envelope. That's the work that actually ends it, it's the owner's asset, and paying for it out of your own pocket on a twelve-month lease rarely makes sense. Landlord & tenant responsibility in Texas »
One thing to be clear about: we can inspect a rental and tell you exactly what's happening, and that report is useful to give a landlord. But we can't perform structural work on a property without the owner's authorization. If you're a tenant, ask us for the inspection and the documentation — that's the part that helps you.
We offer free inspections to all residents and property owners.
If you own or manage rental property here
Treat the building, not the unit. One-unit treatment in a multi-unit building is the most common wasted spend in rental pest control, because rodents just move to the adjacent cavity.
Do the work during the vacancy window. Late May through July is when a building can actually be sealed, inspected, and decontaminated without scheduling around occupants.
Check vacant units on a schedule. An unoccupied apartment is where the next tenant's problem is being built right now.
The dumpster area at move-out is the biggest single driver on the property. Extra pickups in May and August are cheap compared to a building-wide rodent program.

Frequently asked questions
There are mice in my apartment near UTPB — is that my landlord's responsibility?
In most cases the building envelope and structural sealing are the owner's responsibility rather than the tenant's, but the specifics depend on your lease and on the circumstances, so it isn't a single universal answer. What is universal is the practical step: report it in writing, dated, with photographs, and keep a copy. A documented request is far more effective than a verbal one and it protects you either way. For the detail, see our page on landlord and tenant rodent responsibility in Texas.
Can you treat just my unit in an apartment building?
We can work inside your unit, and you should know going in that in a multi-unit building it's usually a building-level problem — rodents travel shared wall cavities, plumbing chases, and attic spaces between units, so a single-unit treatment tends to produce short-lived results. We also can't perform structural sealing on a building without the owner's authorization. What we can always do for a tenant is inspect and document, which is the thing that moves a landlord.
We just moved in and found mouse droppings — were they already there?
Very often, yes. Units near a university sit empty from late May through July, which is exactly the window when populations establish: food left in cabinets, move-out trash, overflowing dumpsters, and weeks of no disturbance. Check whether the droppings are fresh — dark, soft, and shiny means active, while faded, gray, and brittle means older — and photograph everything with the date before you unpack, because that record matters if a deposit is ever disputed.
Can my landlord charge me for a rodent problem?
That depends on your lease and on the cause, and it's exactly why documenting the condition when you move in is worth five minutes. Photographs and a dated written report showing droppings present before you unpacked are the strongest evidence a tenant can have. If you're already past move-in, report it in writing now — a dated record starting today is better than none.
Should I put out poison in my apartment?
No, and an apartment is the worst place for it. A poisoned rodent dies wherever it happens to be, which in an apartment building means inside a shared wall or ceiling — producing weeks of odor for you and your neighbors, plus flies, and drywall work someone has to authorize. It's also a genuine hazard where pets and children are close by. Snap traps along the walls remove the animal from the building instead.
When is the best time to have a rental property sealed?
Between tenants, which in a university area means late May through July. That's when a building can be inspected, sealed, and decontaminated without working around occupants, and it's also the window when populations quietly establish in vacant units — so the work lands exactly where the risk is. Extra dumpster pickups during May and August move-out are the cheapest complementary change a property owner can make.
Do you charge renters for an inspection?
We offer free inspections to all residents and property owners.
