Treatment Products for Do-It-Yourself Option

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

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.

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. 

How to Order -- Merit 75% WSP is Bayer's original Imidacloprid product for treating HWA.  There are also quite a few generic formulations that are chemically equivalent, equally effective, and less expensive.  When you call to order Imidacloprid, specify that you want "water soluble powder containing 75% Imidacloprid in 1.6 oz packaging for treating the hemlock woolly adelgid."  Then the store will be able to tell you the appropriate product to buy. 

(Note: Please be aware there is a 2.25 oz. packaging of Imidacloprid 75WSP that is labeled as a termiticide.  Using it for treating HWA would constitute an improper off-label use, plus the instructions on the product label would be incorrect for treating HWA, so be sure to choose the 1.6 oz. packaging.)

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 mixing the material.  Transtect 70WSP is a water-soluble powder and is packed in a canister containing twenty 0.6-ounce packets.

More Help -- If you will need a substantial quantity of treatment product, we suggest that you 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.

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; neighborhood associations may have their own requirements for borrowing.

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.
