Comparing costs, effectiveness, and limitations of DIY vs professional approaches.

TL;DR: DIY: 20-40% success rate, limited products; Professional: 90%+ success, proper equipment, warranties—pros recommended for active infestations. — Start with treatment types, then when to call a pro. Prefer to talk? (833) 404-3632.

Educational awareness only: This guide helps you understand your options. For active infestations, professional treatment is strongly recommended.

The decision between DIY and professional termite treatment depends on infestation extent, termite species, property type, and your comfort with chemical application. This guide helps you understand when each approach makes sense and the real costs and risks of each option.

Quick Decision Guide

When Professional Treatment is Essential

Active subterranean termite infestation
Structural damage present
Multiple areas affected
Drywood termites requiring fumigation
Real estate transaction pending
Lender requires treatment documentation
You want warranty protection
Previous DIY treatment failed

When DIY Might Be Considered

Very small, localized drywood infestation
Single piece of non-structural wood
Preventive treatment (no active infestation)
Supplemental to professional treatment
Temporary measure until professional service

Note: Even in these cases, professional treatment is usually more effective

DIY Treatment Options

1. Liquid Termiticides (Consumer Grade)

What they are: Diluted insecticides applied to soil or wood

Common products:

Bifenthrin (Bifen IT, Talstar)
Permethrin
Imidacloprid (some formulations)

Application:

Trench and treat around foundation
Drill and inject into walls or soil
Spray on wood surfaces

Pros:

Lower upfront cost ($50-300 for materials)
Available at hardware stores
Can treat small areas

Cons:

Consumer products less concentrated than professional
Difficult to achieve complete coverage
No warranty or guarantee
Requires specialized equipment (trencher, drill)
High risk of incomplete treatment
Safety risks if misapplied

Effectiveness: 20-40% for subterranean termites (vs. 90%+ professional)

2. Borate Wood Treatments

What they are: Boron-based preservatives applied to wood

Common products:

Bora-Care
Tim-bor
Boracare

Application:

Spray or brush onto bare wood
Inject into existing wood
Soak wood before installation

Pros:

Low toxicity to humans and pets
Long-lasting protection
Also prevents rot and mold
Good for preventive treatment

Cons:

Only works on exposed wood
Water-soluble (indoor use only)
Won't kill colony (only protects treated wood)
Requires bare wood (won't penetrate paint/finish)
Not effective for active subterranean infestations

Best use: Preventive treatment during construction or renovation

3. Termite Foam

What it is: Expanding foam containing termiticide

Application:

Inject into wall voids
Fill cracks and gaps
Treat hollow spaces

Pros:

Reaches inaccessible areas
Expands to fill voids
Easier than liquid for some applications

Cons:

Limited coverage area
Expensive for large areas
Doesn't create soil barrier
Temporary solution only

Best use: Spot treatment in walls (supplemental to other methods)

4. Cardboard Traps

What they are: Wet cardboard placed to attract termites

How it works:

Termites attracted to cellulose
Remove and destroy cardboard with termites
Repeat process

Pros:

Non-toxic
Very cheap
Can help monitor activity

Cons:

Ineffective for actual control
Only catches small number of workers
Doesn't affect colony
Labor-intensive
Won't eliminate infestation

Best use: Monitoring only, not treatment

Professional Treatment Options

What Professionals Offer

1. Professional-grade products:

Higher concentration termiticides
Non-repellent formulations (Termidor, Premise)
Products not available to consumers
More effective active ingredients

2. Specialized equipment:

High-pressure injection systems
Soil treatment rigs
Fumigation equipment
Detection technology

3. Expertise and training:

Species identification
Proper application techniques
Building construction knowledge
Safety protocols
Treatment method selection

4. Comprehensive approach:

Complete property inspection
Treatment of all affected areas
Follow-up inspections
Warranty protection
Documentation for real estate

Cost Comparison

DIY Costs

Materials:

Termiticide: $50-150
Sprayer: $30-100

Total: $150-500+

Hidden costs:

Time (20-40 hours for full treatment)
Retreatment if unsuccessful
Potential damage from improper application
No warranty or guarantee
Professional treatment still needed if DIY fails

Professional Costs

Typical pricing:

Initial treatment: $1,500-3,500 (average home)
Annual warranty: $200-400/year
Includes inspection, treatment, follow-up

Value included:

Professional inspection and diagnosis
Complete treatment of all areas
Warranty (typically 1-5 years)
Retreatment if termites return
Documentation for real estate
Peace of mind

Effectiveness Comparison

Success Rates

DIY treatment:

Subterranean termites: 20-40% elimination rate
Drywood termites (localized): 30-50%
Often requires multiple applications
High recurrence rate (50-70%)
Partial treatment common

Professional treatment:

Subterranean termites: 90-95% elimination rate
Drywood termites (fumigation): 99%+
Single treatment usually sufficient
Low recurrence with warranty maintenance
Complete coverage standard

Safety Considerations

DIY Safety Risks

Improper mixing can create hazardous concentrations
Inadequate protective equipment
Contamination of water sources
Exposure to children and pets
Structural damage from drilling/trenching
Liability if neighbors affected

Professional Safety Protocols

Licensed applicators with training
Proper protective equipment
Regulated application rates
Environmental safeguards
Insurance coverage
Compliance with regulations

Common DIY Mistakes

Why DIY Often Fails

1. Incomplete treatment:

Missing hidden colonies
Inadequate soil coverage
Gaps in barrier
Insufficient product application

2. Wrong product selection:

Using repellent when non-repellent needed
Insufficient concentration
Wrong product for termite species

3. Improper application:

Incorrect dilution ratios
Inadequate soil saturation
Poor timing
Missing critical areas

4. Lack of follow-up:

No post-treatment inspection
Failure to monitor effectiveness
No retreatment when needed

When DIY Makes Sense

Limited Scenarios

1. Preventive borate treatment:

During construction or major renovation
Exposed framing accessible
No active infestation
Supplemental to professional soil treatment

2. Single piece of furniture:

Isolated drywood infestation
Non-structural item
Can be removed from home
Freezing or heat treatment possible

3. Temporary measure:

Waiting for professional appointment
Spot treatment to slow spread
Understanding it's not a solution

The Real Cost of DIY Failure

Continued damage: $500-5,000+ while infestation persists
Wasted DIY costs: $150-500
Professional treatment still needed: $1,500-3,500
Additional damage repair: $1,000-10,000+
Time and stress: Months of worry
Total potential cost: $3,150-19,000+ vs. $1,500-3,500 for professional from start

Making the Decision

Questions to Ask Yourself

Is this an active infestation or just prevention?
How extensive is the problem?
What species am I dealing with?
Do I have the time and equipment?
Am I comfortable with chemical application?
Can I afford to fail and start over?
Do I need documentation for real estate?
What's the risk if treatment is incomplete?

Recommended Approach

Best Practice

Get professional inspection first ($75-150)
Understand extent and species
Get 2-3 professional quotes
Compare to DIY realistic costs (including time and risk)
Choose professional for active infestations
Consider DIY only for prevention (with professional guidance)

Common Questions

Can DIY treatment work for active infestations?

Rarely. DIY success rate is 20-40% vs 90%+ for professionals. Failed DIY allows continued damage—professional treatment more cost-effective long-term.

When is DIY appropriate?

Prevention only: treating exposed wood, applying borate to new lumber. Never for active infestations—always use licensed professionals.
