It's spring, and termites are swarming. With that comes another chance for termites to invade homes and businesses in Texas.
Two major groups of subterranean termites — natives and Formosan — make Texas their home.
Native subterranean termites have already swarmed in South Texas, and it is now swarming season in Central and North Texas, said Dr. Roger Gold, Texas Cooperative Extension entomologist.
Considered the most destructive insect wood pests in the U.S., subterranean termites cause more than $2 billion in damage each year. Subterranean termites are found throughout the U.S., with the greatest concentration in the Southeast.
Native subterranean termites live in nests or colonies in the soil, Gold said, and feed on dead trees and brush. But when land is cleared of this material for construction of buildings, termites will attack these structures, he said.
These insects enter buildings through wood in direct contact with the soil, shelter tubes they build or directly through cracks or joints in and under foundations, he said.
The primary native subterranean termite which is swarming now is coal black to yellow-brown, about one-fourth to three-eighths of an inch in length (a little longer than a pencil eraser), and has wings with a few distinct veins, he said.
Formosan termites swarm in the summer. This termite is a newcomer, having only been in Texas for a little more than 50 years.
The ones that swarm are yellowish-brown, about a half-inch long, and have wings with two heavily pigmented veins near the front edge and no connecting cross veins.
Formosan termites often make aerial nests — commonly called a carton — of wood, saliva and fecal material. These can be as large as several cubic feet and may not have ground contact.
Even though they cause the same type of damage as native subterranean termites, they inflict this damage more rapidly.
Also, more than 47 plant species such as pecan, citrus, wild cherry, cherry laurel, sweet gum, cedar, willow and wax myrtle have been attacked by Formosan termites.
"Formosan termites also have been known to eat through non-cellulose material, such as thin sheets of soft metal such as lead or copper, asphalt, plaster, creosote, rubber and plastic searching for food and moisture," Gold said.
If termites are found swarming around or inside a home, don't panic, Gold said.
"Termites usually work slowly, so your house will generally not collapse or be ruined overnight," he said.
He advised following these steps:
— Take the time to learn more about termites, their biology, inspection techniques and treatment options.
— Do not permit anyone to rush you into buying termite control services. Take the time you need to make an informed decision.
— If you are unsure about termites being present, arrange for a thorough termite inspection with a licensed, reputable company.
"Know that costs of inspections, estimates and terms can vary significantly among companies," Gold said. "Ask for inspections from three or more companies. Ask for recommendations from your friends and neighbors. This is the best way to get an honest opinion about a termite control service.

Teachers invited to
summer Master Gardener training
By Rod Santa Ana III
Space should not be a problem this year in South Texas as Texas Cooperative Extension holds its summer Master Gardener and Junior Master Gardener training for school teachers June 5 though 10.
Every year, the event attracts more prospective participants than the facilities could hold, but not this year, according to Barbara Storz, event organizer and Extension horticulturist for Hidalgo County.
"Each year we've had to turn people away for lack of space," Storz said. "But this year's program will be hosted by Weslaco High School, where facilities are quite spacious."
Storz said some of the workshops will be held in the award-winning Botanical Garden Classroom created by Weslaco High School science teacher Dr. Debbie Villalon and her students.
"We are so fortunate that Dr. Villalon and her principal, Dr. Isidoro Nieto, were willing to share this beautiful environment for our training," Storz said.
Villalon completed the summer Master Gardener training two years ago. Then she and her students built an outdoor garden learning lab, which recently won the Governor's 2006 Texas Environmental Excellence Award.
"We all learn by example, and the Weslaco High School Botanical Garden is a great example to share with teachers from throughout the Rio Grande Valley," she said.
This year's training for educators will include outdoor workshops and indoor presentations by other successful teachers, Master Gardeners, Extension staff, and local professionals. Teachers will learn how to develop outdoor, hands-on classrooms that cultivate success for their students, Storz said.
"Teachers will then spend the year sharing their gardening knowledge and working toward certification as Texas Master Gardeners," she said. "Their students will become certified as Junior Master Gardeners."
The program now has five Junior Master Gardener curriculums. Three are geared to the elementary level and two at the middle school level. All are tied to the Texas Essential Knowledge and Skills in math, science, language arts, and social studies.
"The curriculums are filled with hands-on activities that truly engage youth and improve test scores," Storz said. "This year, librarians and teachers at the elementary level will choose one of three curriculums. One is 'Literature in the Garden,' based on six classic children's stories; 'Wildlife Gardener,' which establishes a habitat garden; and 'Health and Nutrition from the Garden,' which is based on building a vegetable garden and learning about nutrition."
At the middle school level, educators will choose from "Operation Thistle: Seeds of Dispair," a botany course involving "missions" to rid the garden of the "bad" Dr. Thistle character, or "Water and Earth's Resources," which takes students hot on the trail of the evil Dr. Thistle, while exploring the important roles of water and soils in supporting life.
"The elementary level curriculum can be adjusted for kinder through high school," Storz said, "and the middle school program can be adjusted to high school, which is what Dr. Villalon did."
Cost of the six-day training, including adult program books, youth curriculum, and vegetable and flower seeds is $150. Registration deadline is May 19.
Weslaco High School is located at 1005 West Pike St. in Weslaco.

The flower garden:
Tips for better blooms
Summertime in Texas is a unique gardening season. Here we have some perennials like peonies and bleeding hearts that go completely dormant and others that hunker down and quit blooming 'til fall; annuals that won't reseed again until next spring (no matter what the seed packet says about blooming "all summer long"); and then some sensational heat lovers, both annual and perennial, that save the day from June until the first frosts. Keeping this in mind, what can we do for our beds while we still have gorgeous weather to enjoy the garden in?
First take a look at your spring blooming annuals. Have you saved all the seed you wanted? Though larkspur, nigella and poppies self-sow, you'll get the colors you want, where you want, by saving seed, storing it in a cool, dry place and scattering it in the fall. Pull up or chop off the last flower stalks, making room and sunlight for any perennials that are emerging. Check on and thin your summer annuals like zinnias, cosmos and marigold which should be off to a good start by now.
