Who This Is For
This guide is for Florida homeowners, families with children and pets, and anyone who spends time outdoors in grassy or brushy areas. Whether you’re dealing with a backyard infestation, planning to treat a vacation property, or just want to prevent bites on hiking trips, this information will help you take action.
The Problem
Chiggers are the larval stage of harvest mites (Trombiculidae). Only the larvae bite, and they do not burrow into skin. Instead, they attach to skin pores or hair follicles and inject digestive enzymes that liquefy skin cells. The resulting red welts can itch intensely for days or weeks. In Florida, the warm, humid climate allows chigger populations to thrive from late spring through early fall, and in South Florida, activity can persist year-round. The mites concentrate in tall grass, brush, shaded ground cover, and along edges of lawns and wooded areas. They are most active in the afternoon when ground temperatures are between 77 and 86°F.
Warning Signs
- •Intense itching, especially around ankles, waist, armpits, and behind knees, often occurring 1-3 hours after outdoor activity.
- •Small, red, raised welts that may develop into blisters; bites often appear in clusters or lines.
- •Seeing tiny red or orange mites on clothing or skin after walking through grass or brush.
- •Presence of chiggers in known habitat: tall grass, brush, shaded leaf litter, or overgrown edges near lawns.
- •Multiple family members or pets showing similar itchy welts after spending time in the same area.
- •Pets scratching excessively, especially on belly, ears, or between toes.
Risks of Waiting
- ⚠Prolonged itching can lead to secondary skin infections from scratching.
- ⚠Infestations can spread as chiggers move to new areas via clothing, pets, or lawn maintenance equipment.
- ⚠Increased risk of bites for children and pets who play in untreated yards.
- ⚠Chigger populations can grow rapidly in favorable conditions, making later treatment more difficult.

Treatment Options
Broadcast Granular Insecticide
$30-$60 for DIYApply granular insecticide containing bifenthrin or permethrin using a spreader. Water in after application to activate. Provides 2-4 weeks of control.
Liquid Spray Treatment
$40-$100 for DIY; $100-$300 for professionalUse a hose-end sprayer or backpack sprayer to apply liquid bifenthrin, cyfluthrin, or lambda-cyhalothrin to grass and brush edges. Offers longer residual than granules.
Professional Perimeter Treatment
$100-$450 per treatmentLicensed pest control professionals apply specialized formulations with residual barrier properties. Often includes follow-up visits and integrated pest management strategies.
Understanding Chigger Biology and Behavior
Chiggers are the larval stage of harvest mites, belonging to the family Trombiculidae. Only the larvae bite; adults are harmless and feed on plant material. The larvae are tiny, about 0.15-0.3 mm, and are red or orange. They do not burrow into skin. Instead, they attach to skin pores or hair follicles and inject digestive enzymes that break down skin cells. The host’s immune reaction to these enzymes causes the intense itching and welts. Chiggers typically feed for 3-4 days before dropping off. They prefer areas where clothing fits tightly, such as ankles, waist, armpits, and behind knees. In Florida, the warm, humid climate supports multiple generations per year, with peak activity from May through September. Chiggers are most active in the afternoon when ground temperatures are between 77 and 86°F. They are not found in dry, open areas like sunny lawns, but thrive in shaded, moist microhabitats.
A Statewide Guide to Chigger Activity in Florida
Florida’s diverse climate zones create variation in chigger activity. In North Florida, including cities like Jacksonville, Tallahassee, and Gainesville, chigger season runs from late April through October, with peak in June-August. The cooler winters reduce populations, but mild springs allow early buildup. Central Florida, including Orlando, Tampa, and Daytona Beach, experiences a longer season from April through November. The subtropical climate supports chiggers year-round in some sheltered areas. South Florida, including Miami, Fort Lauderdale, and Naples, sees chigger activity essentially year-round, though bites are most common during the rainy season (May-October). In all regions, chiggers are concentrated in tall grass, brush, shaded ground cover, and along edges between lawns and woods. Urban areas with well-maintained lawns have fewer chiggers, but parks, hiking trails, and undeveloped lots can harbor high populations. For city-specific information, readers are encouraged to contact local pest control providers.
Effective Treatment Strategies for Florida Homes
Integrated pest management (IPM) is the most effective approach for chigger control. Start with habitat modification: mow grass to 3 inches or less, remove brush and leaf litter, and create a barrier of wood chips or gravel between lawn and wooded areas. This reduces suitable habitat. Next, apply insecticides as needed. For lawns, granular bifenthrin or permethrin products provide easy coverage. For targeted areas like fence lines and brush edges, liquid spray with bifenthrin, cyfluthrin, or lambda-cyhalothrin works well. Always follow label instructions. In Florida, treatments may need to be repeated every 4-6 weeks during peak season. Professional pest control can provide longer-lasting results with specialized formulations and application equipment. After treatment, avoid re-entering the area until spray has dried (usually 2-4 hours). For personal protection, use DEET or permethrin-treated clothing. Treating pets with vet-approved products also helps reduce the risk of bringing chiggers indoors.

When to Call a Professional
If you have a large property, a heavy infestation, or if DIY treatments fail to provide relief after two applications, it’s time to call a professional. Also consider hiring a pro if you have small children or pets with sensitive skin, or if you want a guaranteed solution without the hassle of handling pesticides.
DIY vs Professional
DIY treatments can be effective for small, contained areas. Granular and liquid insecticides are readily available at garden centers. However, misapplication can lead to poor results or unnecessary pesticide use. Professional services offer targeted application, stronger formulations, and often a service guarantee. For example, Chigger Control provides inspection terms that vary by provider and written warranty terms that vary by provider. If you value your time and want the best chance of eliminating chiggers quickly, hiring a pro is worth the investment.

💡 Did You Know?
- ★Chiggers don't burrow into skin; they inject digestive enzymes that liquefy skin cells, which causes the intense itch.
- ★The red welts from chigger bites are actually the body's immune reaction to the mite's saliva, not the mite itself.
- ★Only larval chiggers bite; adult mites are harmless plant-feeders.
