3 Warnings!


#1 - This Subject is VERY Boring!


#1 - This Subject is VERY Boring!Fortunately, I am not above pandering & bribes!


#2 - Difficult to pick a level that works for everyone




-Too basic, lose the very experienced folks




-Too advanced, lose the beginners

who really need help




-Too advanced, lose the beginners

who really need help

Solution: Go with very basic version,

and ask the pro’s to help

#3 NM Dept of Ag - Cracking Down!mess up your calculations & you WILL be fined!




- Graph Paper

- Accurate drawings & measurements

- Accurately show & describe infestations

- Calculated gallons must = actual gallons



- Graph Paper

- Accurate drawings & measurements

- Accurately show & describe infestations

- Calculated gallons must = actual gallons

Make it clear & easy for NMDA to understand what you did & why

Before We Crunch the Numbers:

- Share experiences

- Ask Questions

- Examples from Jack Root


Not Talking about:

- Equipment calibration

- Mix Rates/Tank Mixes

- Application techniques


Before you start applying termiticide, Be Prepared:


- Graph Paper & Pencils

- Measuring Wheel (Univar Booth)

- Review sales quote

- Review mix already in tank

- Determine additional mix rate

- Determine construction type

- Read Label

Some Key Numbers:

- Horizontal Barrier

1 gallon/10 square feetexample: floor


Some Key Numbers:

- Horizontal Barrier

1 gallon/10 square feetexample: floor

- Vertical Barrier

4 gallons/10 linear feet (per foot of depth)

examples: perimeters, control cracks, protrusions,

grade changes, bath traps, abutting slabs

Example 4 - Geometric Shapes


-Not every house is a perfect square

- We need to calculate areas & perimeters



Area = L x W

Perimeter = L + L + W + W

W

L



Area = 3.14 x r x r (π * r2)

Circumference – 3.14 x r x 2 (π * d)

r



Area = ½ B x H

Perimeter = S1 + S2 + S3

B

H



Area = (T + B)/2 x H

Perimeter = S + S + T + B

T

HS

B

Example 4 - Geometric ShapesArea = (T + B)/2 x H

Perimeter = S + S + T + B

T

HS

B

Trapezoid

Rectangle + 2 triangles



BA

Area = (A x B) x 3.14

Circumference – calculus

(fuggedaboutit)



Break complex shapes down

into smaller, bite-size chunks!

Example 5 - Sloping Grade


.

30 lineal feet

3’ depth to footer




.

30 lineal feet



Average depth to footer = High end + Low end/2

(3’ + 5’)/2 = 4’ average depth to footer



.

30 lineal feet



4’ average depth to footer

30 lineal feet x 4 = 12 gallons x 4’ average depth = 48 gallons

.

30 lineal feet



Course aggregates may also require more termiticide

Remember, Preparation is Key


- Graph Paper & Pencils

- Measuring Wheel

- Review sales quote

- Cheat Sheets

- Know construction style, label

- Ask for Help (no guessing)
