Rodents in Oxford follow a calendar: frost, breeding seasons, student move-outs, storms. Here is what is happening each month, and the one or two things worth doing before it does.
- First frost ~ Oct 26
- Last frost ~ Apr 10
- Squirrel litters twice a year
- Seal before fall

When is the best time for rodent control in north Mississippi?
Late summer and early fall, before the first frost. In Oxford the average first frost is about October 26 and the average last frost about April 10, based on NOAA normals for the University, MS station. Mice and rats move indoors as nights cool, so sealing gaps in September and early October keeps them out instead of trapping them inside. Squirrels have young in January to March and again in June to August, according to Mississippi State University Extension, so roofline sealing for squirrels is best done in April and May or September to December. Rodents do not hibernate, so a quick check each season, plus checks before long vacancies like winter break and summer, keeps small problems small.
Month by month
Month-by-month rodent calendar for Oxford
Frost dates from NOAA normals via the Old Farmer’s Almanac; squirrel timing from Mississippi State University Extension.
| Month | What is happening | What to do |
|---|---|---|
| January | Squirrel litters begin; cold snaps; ice storm season | Check the roofline after storms; do not seal over squirrel nests |
| February | Mice and rats active indoors; squirrel young in nests | Keep trapping indoor activity; clean up droppings safely |
| March | Squirrel litters; spring breeding starts | Trim limbs before leaf-out; plan roofline work for April |
| April | Last frost ~ April 10; young squirrels leaving nests | Good window for roofline sealing and one-way doors |
| May | Student move-out; units empty | Seal and trap empty rentals; clear food left behind |
| June | Summer squirrel litters begin; vacant units | Check stored food and garages; inspect empty homes |
| July | Peak heat; dead rodent smells travel fast in attics | Check vents and crawl space; keep pet food sealed |
| August | Move-in; summer litters; rodents start scouting | Fix move-in issues fast; walk the outside of the house |
| September | Nights begin to cool | Best month to seal gaps before the cold |
| October | First frost ~ October 26; mice move indoors | Seal now; set traps at the first sign |
| November | Peak indoor activity | Trap, confirm with a quiet week, keep gaps sealed |
| December | Winter break vacancies; holiday food | Clear food before leaving; set traps in empty units |
Frost dates are 30% probability averages from 1991 to 2020 NOAA normals, so a frost a week or two either side is normal.
Pre-season checklist
The pre-season sealing checklist
Do this in September and you will do a lot less in November.
Walk the outside
Look where pipes and lines enter, at garage door corners, under doors and at crawl space vents.
Trim limbs
Cut back branches touching or hanging over the roof.
Seal small gaps
Steel wool or copper mesh plus caulk in anything a pencil fits into.
Cover vents
1/4 inch hardware cloth on crawl space, gable and soffit vents.
Store food
Pet food, birdseed and pantry staples in metal or hard plastic.
Set a few traps
Snap traps along garage and kitchen walls catch scouts early.
More on each step in our DIY guide and exclusion guide.
Rental calendar
The Oxford rental calendar and rodents
School-year rhythms create rodent rhythms.
More than half of Oxford’s occupied homes are rented, and much of the rental market runs on the school year. That creates predictable rodent windows: units sit empty over winter break and summer, and food left behind feeds mice for weeks.
Landlords: the empty weeks between leases are the cheapest time to seal a unit. Renters: clear food and empty the trash before every break. More in our landlord guide and renters guide.
- December: clear food before winter break
- January: check units when tenants return
- May: seal empty units after move-out
- Summer: inspect vacant units monthly
- August: document conditions at move-in
- Fall: respond to the first complaint fast
Beat the season
Want the gaps sealed before the next season starts?
Call or send the form. We find every entry point, seal it with metal and set traps for anything already inside. The price is in writing before any work starts.
By season
What each season means for rodents
Rodents do not hibernate. They just move to wherever it is warm and fed.
Spring
Breeding picks up and young squirrels leave nests. A good time to trim limbs and seal the roofline once nests are empty.
Summer
Second squirrel litters, empty student rentals and heat. Watch stored food, garages and closed-up homes.
Fall
The big one. Mice and rats move indoors as nights cool. Seal in September and early October, before the first frost.
Winter
Rodents inside stay inside and breed. Winter storms damage rooflines. Trap what is in, and check the roof after storms.

Straight answers
Seasonal rodent questions
When do mice come inside in Mississippi?
Mostly in fall as nights cool. In Oxford the average first frost is about October 26, and indoor mouse activity rises from the first cool snap through winter.
Is there a rodent season in Mississippi?
Fall and winter are the busiest indoors, but rodents do not hibernate and breed year round in sheltered places. Squirrels have two litter seasons: January to March and June to August.
When should I seal my house against rodents?
September and early October, before the first frost. Sealing earlier keeps them out; sealing in winter means trapping the ones already inside at the same time.
When is the best time to deal with squirrels in the attic?
April to May or September to December, between litter seasons, so young are not trapped inside. Always check for young before sealing.
Do rodents go away in summer?
Not usually. Mice and rats that are living indoors stay as long as there is food and shelter. Summer vacancies in rentals can actually make it easier for them to settle in.
When is the last frost in Oxford?
About April 10 on average, based on 1991 to 2020 NOAA normals for the University, MS station.
