Treatment Products

Recommended Products -- For lightly to moderately infested hemlocks, Imidacloprid 75% WSP or 22.6% 2F (sold under various brand names) is the recommended treatment.  For heavily infested or very large infested hemlocks, a different product containing Dinotefuran (sold as Safari 20 SG or Transtect 70WSP) is recommended.  In addition to these primary products, there are other consumer products that do-it-yourselfers may consider.  Click below for:

Retail Sources for Property Owners -- HWA treatment products are available from many sources, including the Internet.  Below is a partial list of local retailers that carry them; this alphabetical list is meant for information purposes only, not as a company endorsement.  The GA Forestry Commission’s web site also has a list of insecticide vendors.  If you know of other retailers that should be added to the list, please let us know. 

We suggest you call ahead to be sure the product you want is in stock.  And if you will need a substantial quantity of treatment product, it's a good idea to call more than one supplier to compare products, prices, and any available volume discounts before making your choice.  If you need advice or have questions on the most appropriate treatment product to use for special circumstances, the quantity needed, product characteristics, etc., please call the Hemlock Help Line 706-429-8010.

I = Imidacloprid products, D = Dinotefuran (Safari 20 SG)

Special Notes to Property Owners -- Merit 75% WSP is Bayer's original Imidacloprid product for treating HWA.  However, there are quite a few generic formulations in liquid or powdered form that are chemically equivalent, equally effective, and much less expensive.  When you call to order Imidacloprid, specify that you want a "generic Imidacloprid product for treating hemlock woolly adelgids."  Then the store will be able to tell you the appropriate product to buy. 

Please be aware that most 2.25 oz. packaging of Imidacloprid 75WSP is labeled for termite treatment, and using it would be "off label."  However, there is one 2.25 oz. product (Equil Adonis) that is labeled for adelgids; see the Chemical Controls page.

Safari 20 SG is a water-soluble granule and is packaged in either a 12-ounce or 3-pound container.  It comes with a specially marked measuring cup to use for measuring the product.  Transtect 70 WSP is a water-soluble powder and is packed in a canister containing twenty 0.6-ounce packets, but it's difficult to find in the southeast.

Wholesale Sources for Professionals and Retailers -- We want to encourage as many retailers as possible to carry HWA treatment products in the hope that if property owners can find them locally, they will save more hemlocks.  Therefore, to make it easier for retailers to find wholesalers that sell the appropriate products, we've developed a partial list of insecticide wholesalers for the Georgia market.  This alphabetical list is meant for information purposes only, not as a company endorsement.  If you know of other wholesalers that should be added to the list, please let us know.

Soil Injectors

Borrowing -- Once you have acquired the necessary treatment product, you may call one of the locations listed below and request to borrow a soil injector.  In addition, quite a few neighborhood associations (not listed here) have purchased injectors for lending to residents.  There is no fee for borrowing from any of the locations listed below, but a refundable deposit may be required.  Please refer to the Georgia Forestry Commission's Soil Injector Loan Program for their rules for borrowing; in addition, neighborhood associations may have their own requirements.

Other equipment such as back-pack or sled-style sprayers may be found at retailers such as Home Depot, Lowe's, John Deere Landscapes, Tractor Supply, or your local farm co-op or hardware store.  All product and source names mentioned above are meant for informational purposes only, not as product or company endorsements.

Qualified Professionals Specializing in Hemlocks

If you want to contract with a professional to treat your hemlocks, here are the qualifications that we recommend you should look for:

n   License -- has a current contractor's pesticide applicator license issued by the State of Georgia in the appropriate categories (Forest Pest Control and/or Ornamental and Turf Pest Control);

n   Insurance -- has at least the minimum liability insurance required by the State of Georgia;

n   Expertise -- specializes in treating hemlocks and offers application methods other than trunk injection;

n   Availability -- covers the part of north Georgia where your property is located; and

n   Pricing -- provides services at reasonable rates.

Here are some local companies that we know meet the above qualifications.  These and other licensed HWA Pesticide Applicators are also listed on the Georgia Forestry Commission's web site.  We suggest that you call more than one company to compare services and prices before making your choice.
