Beautiful bugs! “We typically think of insects as pests or pestilences, carrying disease or gnawing their way through our gardens before we can get a bite. But they are also gorgeous creatures, as photographer Levon Biss explores in his latest book, Microsculpture: Portraits of Insects. The book is a continuation of his Microsculpture exhibit at Oxford’s Museum of Natural History, which displayed bugs from the collection in a larger-than-life way.” Enjoy!

Ants! They’re likely major players in perhaps one of the oldest good-news-bad-news stories ever.
The good news is that ants are valued for their beneficial activities. They add large quantities of spent plant and animal remains into the soil surrounding their colonies as they cultivate and aerate the soil. They also create channels for water and roots. They’re predators, too, and are members of nature’s clean-up crew, carting away debris that includes stray crumbs indoors and dead insects outdoors.
The bad news is that, outdoors, ants sometimes get carried away. If they aerate the soil in and around a rootball excessively, water passes through the ground too rapidly to soak in, the plant wilts, and may die. Then, too, people take a dismal view of their uninvited excursions indoors when they trail across the floor, headed for the pet’s dish or wayward crumbs.
Overall, it’s safe to say that most people detest the little buggers. People don’t want to control them. They want to eradicate them. Forever!.
Well, the cold, hard truth is this: That’s not possible; ants are here to stay.
Everyone, clients and Master Gardeners alike, must discard their dreams to eradicate ants. The more accurate strategy, although far less comforting, is to hope to manage ants.
Odorous house ants, Tapinoma sessile, are probably the most common house-invading ants across the country. They’re small, dark brown or black ants, 1/16- to 1/8-inch long, with the usual 3 body parts of an insect – head, thorax, and abdomen. The characters which define them as ants are a petiole (a narrow connection between the thorax and abdomen) and a pair of elbowed antennae. The character which differentiates them from other ants is the single node on the petiole; it’s small and hidden by the abdomen. When crushed, these ants emit a rather penetrating odor, likened to rotted coconut.
Colonies are relatively small, to about 10,000 individuals, each with multiple queens. Nests are usually outdoors just below the soil surface, underneath pavers, wood piles, or other debris. But nests may also be indoors, in a wall void or near warmth-emitting sources.
Odorous house ant populations enlarge by one of two methods: mating of reproductives or via budding. Budding may be triggered when a hundred or so workers transport several of the colony’s queens to a new site. With time, a series of closely related, cooperative colonies—a supercolony – forms.
Sweets are a favorite food but they will eat most any people or pet food.
Managing ants requires a multi-pronged approach.
- Sanitation (clean up regularly), and store perishable foodstuffs in tight, rigid containers.
- Caulk and seal entries such as cracks in the foundation or gaps where utilities enter structures.
- Limit honeydew-producing insects: ants, mealybugs, whiteflies, and scale, both soft and cottony scales.
- Limit access indoors by trimming foliage away from structures.
- Use commercially-formulated ant baits and repeat as needed.
Ant baits are superior to sprays but require more time to be effective, occasionally several weeks. The reason? They are shared with other ants within the colony, including the queens. If a bait is ineffective after a week or more, try a different kind. It can be useful to pre-bait by first setting out a small dab of jam or other food.
Active ingredients in commercial ant baits
- Avermectin – Derived from soil bacteria; affects the nervous system. https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/avermectin
- Boric acid – An inorganic compound used in ant management for years. Mode of action unknown.
- Fipronil – Causes hyperexcitation of the central nervous system causing convulsions and death. Very active against ants.
- Hydramethylnon – Interferes with energy production.
- Imidacloprid – Useful in baits for ants that prefer sweets.
- Insect growth regulators (IGRs) – The queen’s reproductive organs degenerate and immatures die before they become adults.
- Indoxacarb – Activated by enzymes inside the insect.
- Spinosad – Produced by soil actinomycetes; the insect dies of exhaustion because of continuous activation of motor neurons.
- Sulfuramid – Potentiated by enzymes inside the insect body; toxic metabolites inhibit energy production.

Spring is on the verge of emerging and so is a brand, new Master Gardener season. February is a great month to polish your MG badge and renew your engagement in volunteer activities and continuing education opportunities.
It is also an opportunity for you to help usher in the new class of trainees. Come sit in on one of the MG training sessions (here’s the schedule). Introduce yourself to a trainee. Sign-up for phone clinics and farmers’ markets (via CERVIS,) so new trainees can have the experience of working with someone who can show them the ropes. Share your passion for gardening and the Master Gardener program with the new trainees. Note: phone clinic schedules and farmers markets will open at staggered times in the next few weeks. Please check back on CERVIS if the event you are looking for is not posted.

Changes to CERVIS Volunteer Registration Service
This year when you sign-up for volunteer events in CERVIS, our online volunteer registration system, you may notice a few changes.
First off, visually it is a bit different in layout, color, and fonts. This system wide change should make navigating the site easier.
We have added shift slots that are specific to 3 different categories of volunteers.
- Veteran Only
- Interns Only
- Veteran or Intern
When registering on CERVIS please sign-up for the appropriate slot.
This change will assist coordinators in adequately filling shifts for their events. This change also will make it clearer and easier for Interns to serve on shifts with Veteran MGs.
All ‘current’ certified 2018 Master Gardeners have access to CERVIS. If you are unable to access CERVIS, please contact: Jordis Yost – firstname.lastname@example.org or Marcia McIntyre – email@example.com .
Last month we posted our Metro Master Gardener Annual Report. The numbers were stunning and a mere reflection of all the good work being done by YOU! Well the good news is even better than we reported. Regarding the number of public contacts Master Gardeners made in 2017, presenting to the community via our Speakers Guild and 10-Minute University we reported 2,820 contacts. Our numbers actually chime-in at 3,927! That is remarkable! Kudos to all who diligently plan, coordinate, prepare, and present engaging, informative, OSU research-based, horticulture research to the gardening public!
Seeking Master Gardener Speakers
Would you like to join in making gardening presentations to community groups through our Speakers Guild? The Metro MG program receives dozens of requests every year for garden presentations. We have a small, but mighty, group of MGs who answer the call and present throughout the 3 counties – but requests greatly exceed what these dedicated MGs can handle. Therefore, we are looking for even more MGs to share their research-based gardening know-how. We will supply support materials, and those interested can shadow experienced presenters. Reach out and have fun making a few presentations a year!
Presentations are needed on a variety of subjects:
- Beginning gardening
- Vegetable gardening
- Fruit trees
- Container Gardening
- IPM for the Home Gardener
- Small Fruits
- Beneficial insects
- Pollinator gardens
- Small space gardening
- Native plants
- Seed starting
- What’s your garden passion that you are willing to share?
Would you like to be part of this vital community outreach? If so, contact Marcia McIntyre, firstname.lastname@example.org
