🔍Identification & Behavior
🦌Blacklegged (Deer) Tick
Reddish-brown, about ⅛-inch long — half the size of the American dog tick. Found in wooded areas along trails. Larvae and nymphs active spring through early summer; adults active spring and fall. Primary vector of Lyme disease in Maryland. Nymphs are most dangerous because they're tiny, hard to spot, and feed for days.
🐕American Dog Tick
Also called the wood tick. Unfed adults are reddish-brown, about 3/16-inch long. Females have a large silver-colored spot behind the head; males have fine silver lines on the back. After feeding, females engorge to ½-inch (grape-sized). Transmits Rocky Mountain spotted fever. Common in grassy areas and along paths.
⭐Lone Star Tick
Adults about ⅛-inch long and brown. Females have a distinctive white spot in the center of their back. Very aggressive biters. Can transmit Rocky Mountain spotted fever, ehrlichiosis, and is associated with alpha-gal syndrome (red meat allergy). Increasingly common in Maryland as range expands northward.
🏠Brown Dog Tick
Reddish-brown, about ⅛-inch long. Feeds primarily on dogs, rarely bites humans. Only tick species that completes its life cycle indoors. Can infest kennels, dog beds, and cracks in walls. Not an important vector of human disease, but heavy infestations require thorough indoor treatment.

Lyme Disease Awareness
Lyme disease is caused by Borrelia burgdorferi bacteria, transmitted primarily by blacklegged/deer ticks. Look for a bull's-eye rash within 30 days (red on light skin, bruise-like on dark skin). Flu-like symptoms may accompany or replace the rash. In ~25% of cases, no rash develops at all. Any client bitten by a tick in Maryland should consult their doctor.
📋IPM Action Steps
1
Site Assessment & Tick Drag
Walk the property perimeter and landscaped areas. Perform a tick drag — pull a 1-yard square of white flannel across vegetation to sample tick populations. Note species, life stage, and density. Map high-risk zones: woodline edges, stone walls, shaded paths, pet resting areas, and leaf litter accumulations.
2
Habitat Modification
Create a 3-foot dry gravel or wood chip barrier between lawn and wooded areas. Remove leaf litter, brush piles, and ground cover from high-traffic zones. Move firewood storage away from the home. Keep grass mowed to 3 inches or shorter in the tick management zone. Trim low branches to increase sunlight and reduce humidity at ground level.
3
Wildlife Exclusion
Discourage deer with fencing or repellent plantings. Eliminate mouse harborage near the home — white-footed mice are the primary Lyme disease reservoir. Seal gaps in foundations and outbuildings. Remove bird feeders that attract rodents. Stack firewood at least 20 feet from the home, elevated off the ground.
4
Botanical Perimeter Treatment
Apply cedarwood oil spray to the tick management zone — the 3–6 foot band where lawn meets woods. Cedar oil repels and kills ticks on contact without harming beneficial insects when applied to targeted border zones. Also treat stone walls, fence lines, and shaded garden borders. Reapply every 3–4 weeks during peak season (April–October).
5
Indoor Assessment (Brown Dog Tick Only)
If brown dog ticks are confirmed indoors, inspect dog sleeping areas, baseboards, window frames, and furniture crevices. Apply food-grade diatomaceous earth in cracks and crevices around pet areas. Treat dog bedding with cedar oil spray. Coordinate with client's veterinarian on tick prevention for pets.
6
Client Education & Monitoring
Teach tick check protocol: full-body check after outdoor activity, paying special attention to hairline, behind ears, underarms, waistband, and between toes. Explain proper tick removal: blunt curved tweezers, steady pressure at the head, pull straight out slowly — never twist, crush, or burn. Leave pheromone-free sticky monitoring cards at property edges. Schedule follow-up tick drag in 4 weeks.
🛠️Prevention & Cultural Controls
🏡Landscaping
Create a dry tick barrier (gravel, wood chips, or rubber mulch) at least 3 feet wide between lawn and woods. Remove leaf litter and brush piles. Keep grass mowed short in the yard. Plant deer-resistant species near the home. Increase sunlight penetration by trimming low tree branches — ticks require humidity and die in dry, sunny conditions.
🐾Pet Protection
Keep pets out of known tick-infested areas, especially in summer. Confine pets to designated sleeping areas and wash bedding weekly. Check pets for ticks after every outdoor session using a flea/tick comb — focus behind ears and between toes. Coordinate with veterinarian on year-round flea/tick prevention (we do not sell or apply pet treatments).
👕Personal Protection
Wear light-colored clothing (easier to spot ticks). Tuck pants into socks. Wear a hat. Use unscented hygiene products outdoors. Apply lemongrass or cedarwood oil-based herbal repellent to clothing and exposed skin. Shower within 2 hours of being in tick habitat. Dry clothes on high heat for 10 minutes to kill any attached ticks.
🐭Rodent Exclusion
White-footed mice are the primary host for Lyme-carrying tick nymphs. Reduce mouse populations by sealing entry points to the home, removing woodpile harborage, securing metal trash containers, and eliminating ground-level food sources. Cross-reference with our mouse field guide for complete exclusion protocol.
⚗️Application Techniques
🌿Cedar Oil Perimeter Spray
Where: 3–6 foot band where lawn meets wooded or brushy areas. Also treat stone walls, fence lines, mulch beds, and garden borders.
How: Apply with pump sprayer to saturation. Best applied in early morning or evening when ticks are most active. Reapply every 3–4 weeks April through October.
Note: Cedar oil is safe for birds and mammals but do not spray near ponds or streams — essential oils are toxic to aquatic life.
🧹Diatomaceous Earth — Indoor (Brown Dog Tick)
Where: Baseboards, cracks around dog sleeping areas, window frames, wall voids near pet areas.
How: Apply thin, barely visible film with hand bellows duster. DE must remain dry to be effective — reapply after any moisture. Vacuum first to remove eggs and debris.
PPE: N95 mask during application. Let dust settle 30 minutes before allowing pets back into treated areas.
🔬Tick Drag Monitoring
Purpose: Quantify tick populations before and after treatment.
How: Drag a 1-yard square of white flannel or corduroy cloth over vegetation for 30 seconds per zone. Check cloth immediately — ticks attach quickly. Record species, life stage (larva/nymph/adult), and count. Repeat at 2-week intervals to track treatment effectiveness. Always wear long pants tucked into socks during dragging.
🧊CO₂ Traps (Supplemental)
Purpose: Reduce local tick populations in high-use areas. Ticks are attracted to CO₂ emitted by hosts.
How: Place 2 lbs dry ice in a ventilated bucket on plywood or flannel with sticky tape around the edge. Trap is active for ~3 hours. Check frequently and remove ticks with tweezers. Soak cloth in soapy water after use.
Note: Supplemental tool only — does not replace habitat modification.

ℹ️
Chemicals We Never Use for Tick Control
Herbal Shield does not use permethrin, bifenthrin, carbaryl, chlorpyrifos, DEET, deltamethrin, diazinon, or any synthetic pyrethroid for tick management. These chemicals are surface water contaminants, wildlife poisons, and bee-toxic — and research shows conventional pesticides are largely ineffective against ticks because ticks spend most of their lives in sheltered harborage where sprays don't reach.

⚠️Warnings & Herbal Shield Standards
🚫
Never Guarantee Tick Elimination
There is no way to completely eliminate ticks from an outdoor area. Always frame our service as tick population reduction and risk mitigation — never as elimination. Overpromising erodes trust and creates liability. Be honest: our goal is to make the property significantly safer, not tick-free.
💧
Aquatic Life — No Spray Near Water
Cedar oil and all essential oils are acutely toxic to fish and aquatic invertebrates. Never spray within 25 feet of ponds, streams, stormwater drains, or the Chesapeake Bay watershed. If a property has water features, adjust the treatment zone and document the buffer on the care card.

Client Script — "Why Don't You Just Spray the Whole Yard?"
"Research shows that broadcast spraying for ticks is largely ineffective because ticks spend most of their lives in sheltered spots — like mouse burrows and leaf litter — where sprays don't reach. What does work is modifying the habitat so ticks can't thrive near your home: dry barriers, short grass, fewer mice, and targeted botanical repellent in the border zone where ticks cross from woods to lawn. It's more work than a spray truck, but it actually reduces your family's risk."

PPE Required: Long pants tucked into socks and treated with cedar oil during all tick work. Conduct a full-body tick check on yourself after every tick service — before entering your vehicle. N95 mask during indoor DE application for brown dog tick infestations.
