Quick answer
Georgia’s spring pest season builds in stages. March warming often brings ants, carpenter bees, overwintering insects, and early termite swarms. April rain and plant growth increase termite, mosquito, ant, and stinging-insect activity. By May, warm nights and repeated storms can produce heavier mosquito, cockroach, flea, tick, and wasp pressure. Weather varies, so identify the pest before deciding what to treat.
Spring in Metro Atlanta is not a switch that turns every pest on at once. Soil temperature, rainfall, flowering plants, indoor heat, moisture, and the building itself determine what appears. Some pests have been inside all winter and simply become more visible; others move from the landscape toward shelter, food, or water.
Dixie Exterminators provides pest control in Marietta and Metro Atlanta, along with separate termite, mosquito, and wildlife services. This month-by-month guide helps homeowners decide what can be monitored, what maintenance matters, and what evidence should be inspected.
Why Pest Activity Increases in a Georgia Spring
Warmer temperatures speed development and movement for many insects. Rain creates moisture, disrupts some outdoor nests, and fills mosquito-breeding containers. New leaves and flowers support pollinators, aphids, and other insects that become food for predators. Longer evenings also increase the time people spend noticing activity outdoors.
Buildings add another layer. Heated wall voids and kitchens can support cockroaches or ants before outdoor weather warms. Roof gaps, crawlspaces, garages, and attics provide shelter for rodents and wildlife year-round. Spring rain then exposes roof, gutter, drainage, and plumbing problems that increase pest pressure.
Not every spring insect is a household pest. Native bees, butterflies, predatory insects, and other beneficial organisms become active too. Control should focus on confirmed risk, indoor infestation, structural damage, or a nest location that creates a practical safety problem.
March Pests in Georgia
Termite swarmers
Eastern subterranean termites commonly swarm from late winter into spring. Warm, humid weather after rain can bring sudden clouds of winged termites or piles of discarded wings. Swarmers inside the home or emerging from the structure justify a termite inspection. Save an intact sample because flying ants can look similar.
The full Atlanta termite swarm guide explains antennae, wing, and waist differences and why spraying swarmers does not eliminate the colony.
Ant trails
Ants may begin foraging more visibly as temperatures rise or may move after rain disturbs outdoor nesting areas. Kitchens, bathrooms, window frames, foundation gaps, and plumbing penetrations are common observation points. Do not spray a trail before identifying the ant and locating where it is feeding; repellent sprays can complicate some bait programs.
Carpenter bees
Large bees hovering around decks, eaves, trim, fences, and unfinished wood may be carpenter bees. Males defend territories but cannot sting. Females can excavate round nesting holes and may reuse old tunnels. Bumblebees have hairier abdomens and usually nest in cavities or underground rather than drilling wood.
Overwintering insects
Lady beetles, stink bugs, paper wasp queens, and other insects that sheltered in or around buildings may emerge on warm days. A few insects at sunny windows can be an exit pattern rather than an active indoor breeding infestation. Vacuuming and later sealing entry gaps may be more useful than broad indoor spraying.
April Pest Problems
Expanded termite activity
Additional subterranean termite species can swarm as spring progresses. Rain, soil moisture, wood-to-soil contact, and damp crawlspaces make termite evidence more noticeable, but no calendar date proves that a building is infested. Inspection should examine accessible foundation areas, mud tubes, wings, damage, and treatment history.
Mosquito breeding sites
Repeated rain fills plant saucers, buckets, toys, tarps, corrugated drainpipe, clogged gutters, birdbaths, and pool covers. Empty and scrub containers weekly. Repair screens and begin using EPA-registered repellent whenever mosquitoes are active rather than waiting for summer.
Wasps and nest building
Paper wasp and hornet colonies begin small. Early nests may appear under eaves, deck rails, porch ceilings, light fixtures, play equipment, and utility boxes. Avoid standing beneath or striking a nest. The location, species, colony size, and allergy risk determine whether professional removal is appropriate.
Flea and tick exposure
Pets, wildlife, tall vegetation, shaded resting sites, and indoor life stages can support fleas or ticks. Work with a veterinarian on pet prevention. Pest service does not replace treatment of the animal, and treating only the yard or only the pet may leave part of the cycle unaddressed.
May Pest Pressure
Mosquitoes become more persistent
Warm nights and storms can shorten mosquito development and continually refill containers. Dense vegetation provides humid resting areas. Property service may reduce activity, but it should be combined with weekly water checks, repellent, screens, and protective clothing.
Outdoor cockroaches move toward buildings
American and smoky brown cockroaches may shelter in drains, crawlspaces, tree holes, mulch, utility areas, and damp debris. Heavy rain, heat, or outdoor population pressure can move individuals indoors. German cockroaches are different: they usually live and reproduce inside and often arrive in packages, appliances, bags, or shared walls.
Ant colonies expand
More food, plant-feeding insects, and warm weather can support larger foraging networks. Trails may lead from trees, mulch, pavement cracks, wall voids, or moisture-damaged wood. Species identification matters because carpenter ants, Argentine ants, odorous house ants, fire ants, and other ants require different strategies.
Stinging insects grow less forgiving
Colonies are still smaller than late-summer nests but can be active around entries and outdoor living areas. Inspect from a safe distance before mowing, trimming, opening utility covers, moving outdoor furniture, or using play equipment.

A Spring Inspection Checklist for the Home
Foundation and crawlspace
- look for mud tubes, standing water, damaged vent screens, and wood touching soil;
- check whether gutters and downspouts discharge away from the building;
- note damp insulation, plumbing leaks, or persistent crawlspace humidity;
- keep the foundation visible rather than buried behind deep mulch or groundcover.
Doors, windows, and utilities
- replace worn door sweeps and weatherstripping;
- repair torn screens and gaps around frames;
- seal appropriate utility penetrations without blocking required ventilation or drainage;
- check garage-door corners and thresholds.
Roofline and attic
- look from the ground for damaged soffits, fascia, vents, and roof returns;
- trim branches and vines away from the structure where practical;
- note scratching, droppings, or staining without entering an unsafe attic;
- schedule qualified repair for storm or moisture damage.
Yard and outdoor storage
- empty standing water and clean gutters;
- store firewood off the ground and away from the house;
- close trash and pet-food containers;
- remove boards, cardboard, pots, and debris resting against the foundation;
- inspect play equipment and outdoor furniture for early wasp nests.
What Routine Pest Control Typically Covers—and What May Be Separate
A recurring general-pest program may target common crawling insects through inspection, exterior treatment where appropriate, indoor service based on activity, and recommendations. Coverage varies by company and agreement.
Termites, mosquitoes, bed bugs, fleas, ticks, fire ants, German cockroaches, stinging-insect nests, rodents, and wildlife often require their own inspection, method, or service scope. Ask what is included rather than assuming “pest control” covers every organism.
What Not to Do This Spring
- Do not identify every winged insect as a termite or every large bee as a stinging threat.
- Do not spray ant trails before a bait or identification plan is established.
- Do not use total-release foggers for cockroaches or other hidden pests.
- Do not apply outdoor products indoors or exceed label directions.
- Do not seal active wildlife or bat openings without confirming timing and occupancy.
- Do not let standing water remain because a yard received mosquito treatment.
- Do not treat pollinators on flowers when they are not nesting in or damaging the structure.
When to Request Professional Help
Arrange an inspection for termite swarmers indoors, recurring cockroach nymphs, a growing wasp nest at an entry, rodents in the living area, repeated bat entry, unexplained damage, or pest activity that returns after reasonable sanitation and exclusion. Bring photographs, samples, dates, and prior treatment records.
A spring visit should end with a specific explanation: what was identified, where evidence was found, what the professional will do, what the homeowner needs to correct, and how the result will be checked.
Frequently Asked Questions
When does spring pest activity start in Georgia?
Activity often increases during March as temperatures rise, but exact timing changes with rainfall, cold snaps, building conditions, and pest species. Some pests remain active indoors through winter and simply become more noticeable in spring.
Are winged insects in spring always termites?
No. Termite swarmers and flying ants can appear at similar times. Save a sample or clear photo and have it identified before deciding on treatment.
Why do ants enter after spring rain?
Rain can flood or disrupt outdoor nesting areas, while indoor food and moisture remain attractive. Trails often develop around foundation gaps, plumbing lines, doors, windows, and vegetation touching the structure.
When should mosquito prevention begin?
Begin property checks before mosquito activity becomes heavy. Remove standing water weekly, maintain screens, and use EPA-registered repellent according to the label whenever mosquitoes are active.
Does quarterly pest control prevent every spring pest?
No service can prevent every insect from appearing. A recurring plan can reduce common pest pressure through inspection, targeted treatment, monitoring, and maintenance recommendations, while termites, mosquitoes, and wildlife may require separate services.
