South Florida Pest Calendar: What Shows Up Each Month
Family-run, licensed and insured pest control in South Florida.
$50 OFF your first service + FREE inspectionNew customers · No code needed · No expirationThis South Florida pest calendar starts with the honest answer: there's no bug-free season here. There are just different pests at different times. The rainy months bring the most mosquitoes and outdoor roaches, cool nights push roof rats toward the attic, and spring brings carpenter bees and the first lovebug flight. Here's what to watch for each month in Broward, Miami-Dade and south Palm Beach, and one thing you can do about it.
What drives the calendar
- Rainy season (May to October). Rain fills containers, and heat speeds everything up. Mosquitoes, no-see-ums, house flies and outdoor roaches all climb.
- Dry season (roughly November to April). Fewer mosquitoes, but they don't disappear. Cool fronts and dry spells push some pests indoors.
- Storms and floods. Water pushes fire ants and other ground pests up and out. See pests after a flood.
- Snowbird season. Homes sit closed for months and pests explore without anyone noticing. See the back-for-the-season checklist.
Pests by month: the South Florida pest calendar
| Month | What to watch for | One thing to do |
|---|---|---|
| January | Roof rats moving indoors on cool nights; spiny orb-weavers on screens and eaves | Look for gaps where AC lines and pipes enter the house |
| February | Carpenter bees starting up; roof rats; spiny orb-weavers | Check wood fascia and eaves for perfectly round holes |
| March | Carpenter bees; ants moving indoors during dry spells | Watch counters and baseboards for ant trails |
| April | Carpenter bees; the first lovebug flight in late April; seasonal residents closing homes | Set up service for a home that will sit empty |
| May | Rainy season starts; lovebugs; mosquitoes climbing; fire ant mounds after rain | Dump and scrub anything that holds water, every week |
| June | Mosquitoes and no-see-ums; more outdoor roach sightings; hurricane season begins | Clear gutters and check the AC drain line |
| July | Mosquitoes; roaches coming in from outside; house flies; golden silk orb-weavers; fruit flies with ripe mangoes | Run water in every drain, especially in unused bathrooms |
| August | Mosquitoes at their busiest; the second lovebug flight in late August; fleas; golden silk orb-weavers | Treat fleas inside and in the yard at the same time |
| September | Lovebugs; mosquitoes; fire ants and roaches pushed out by heavy rain and storms | After a storm, check the yard and pool deck for new mounds |
| October | Rain winding down; spiny orb-weavers showing up; seasonal residents coming back | Do a walk-through of a closed-up home before unpacking |
| November | Mosquitoes still biting; spiny orb-weavers; backyard gatherings | Keep dumping water after every rain |
| December | Roof rats on cool nights; spiny orb-weavers; holiday guests | Check the attic and garage for droppings |
The year-round pests
Some pests don't follow the calendar at all:
- German roaches live indoors, so they breed all year.
- Ghost ants trail across kitchen counters in every month.
- Fleas keep going indoors year-round, with pets or without.
- Bed bugs travel with people, not the weather.
- Drain flies come from the film inside drains, any time of year.
Mosquitoes: the longest season
Mosquitoes are the one pest people expect to be seasonal, and here they aren't. Numbers climb through the rainy season and drop off in the dry months, but they still bite in November and after any warm rain. Our rainy season mosquito guide explains the peak. Our mosquito service is a professional mosquito barrier spray treatment with a backpack fogger, recommended monthly, especially in the rainy season, and we use larvicide on breeding spots around the home.
Spring and fall regulars
- Carpenter bees are around most of the year here. Nest-drilling picks up from late winter into spring, often with a second round in summer, so look for round holes in wood. See the carpenter bee page.
- Lovebugs have two flights, late April to May and late August to September. See the lovebug page.
- Spiny orb-weavers are most noticeable in fall and winter. See the spiny orb-weaver page.
Why a year-round plan
Because something is always active, regular service works better than chasing each season. Our general pest plan is $125 per quarter, about $42 a month, and monthly or custom schedules are quoted after the inspection. For plan customers: "If pests come back between visits, so do we, at no extra cost." There are no long-term contracts and no cancellation fees, just a simple service agreement. We're family-run and licensed, with 30+ years in the business, and hablamos español.
