Save Your Trees 



It takes a lifetime to grow a fine 

 shade tree. A colony of leaf-eating 

 insects can destroy it in one season. 



Tree Tanglefoot will effectually protect 

 shade and fruit trees from most of our des- 

 tructive insect pests, i. e.: 



Canker worms. Tussock moths, Climb- 

 ing cut worms. Brown-tail moths, Woolly 

 aphis, Gypsy Moths, Ants. 



One application stays sticky three months 

 and longer, outlasting ten to twenty times 

 any other substance. Easily appUed with a 

 wooden paddle. One pound makes about ten 

 lineal feet of band. It will not soften, run or 

 melt, yet is always elastic, expanding with 

 growth of tree. Effective rain or shine. 

 Needs no mixing, used exactly as bought.
