Acouple years ago, we were having lots of trouble with ants climbing our front yard birch trees, so i went to the local garden center, and OSH recommended "Tanglefoot" super-sticky tube goop as a barrier to keep the ants out of the birch trees with annual apids. We applied per directions and watched as the ants just walked over stuck bodies of ants until they had re-established a path up all the trees ! Then we had to get this sticky "Tanglefoot" off the birch trees,,,!!! What a mess and pain in the neck !!! Beware, and do not buy this product for this problem and nuisance of ineffective result !!!
Now we have gone 2 years spraying twice with a mild pesticide like malathion and have had little problem with aphids and ants turning our birch tree's leaves black. Cheers,,,also, try alfalfa pellets from your local feed store at $8 for about 50 pound sack on all your roses and flower beds and fruit trees, to add organic matter cheaply to the soil and make lots of worms and their beneficial castings ! Works great !
