first eggs laid by the Queen become
soldiers in order to protect the Queen.
Later, the Queen produces eggs that

,Question 7
An average Eastern subterranean termite
colony is made up of from 1 to 5 million
worker termites in size.
a. True
b. False
Correct Answer
F: The average, single subterranean termite colony of
Reticulitermes flavipes, the Eastern subterranean
termite, contains about 60,000, but may range up to
about 1,000,000 workers.
The average, single Formosan subterranean termite
(Coptotermes formosanus) colony contains about
350,000, but may range up to 2,000,000 to
5,000,000,workers.

, Question 11
Question #1 - How many standard vents (8" x 16") would be needed to meet the
International Residential Building Code for a residential crawl space structure that is
65' long by 30' wide without a vapor barrier?
2
10
15
20
Correct Answer
1. 65*30 = 1950 (square footage of crawl space)
2. 1950/150 (since the crawlspace has less than 70% vapor barrier) = 13
3. 13 * 144 (square inches in a foot) = 1,872
4. 1,872/128 (size of the 8X16 vent) = 14.625
5. Since you can't have .625 of a vent you round up to 15
Question 12
How long is each termite? (In mm)
Correct Answer
Native subterranean termite swarmers are about 7 mm to
10 mm in length, from the tip of their heads to the tip of
their wings.
Formosan subterranean termite swarmers are between 13
and 15 mm in length, from the tip of their heads to the tip
of their wings.
Drywood termite swarmers are generally 10 mm to 13 mm
in length, from the tip of their heads to the tip of their
wings.
Dampwood termite swarmers are from 15 mm to 25 mm in
length, from the tip of their heads to the tip of their wings.
