How do tree bands work?

 

Tree bands work by forming a sticky barrier to adult cankerworm moths. Because cankerworm moths can’t fly, they must crawl up the tree trunk in order to lay eggs in the crown of the tree. Tree bands stop them in their tracks as they attempt to climb.

 

Why are tree bands applied in late summer/early autumn?

 

The fall cankerworm adult, which is a moth, lays its eggs on trees before winter. But first, it has to climb up a tree trunk to get to the crown above. It usually does this after the first severe autumn frost.

By applying the band directly prior to the first hard frosts, we prevent them from ascending the tree.

The bands remain on the tree through spring to also prevent the spring cankerworm moths from making their climb to the crowns of the trees. 

 

Are tree bands guaranteed to prevent infestations?

 

Tree bands work to dramatically reduce the number of canker worm moths that are able to make it into the crown of the tree. However, unless all of the trees surrounding the tree you band are also banded, it is possible for cankerworms to migrate over from unbanded trees. This is why it is important to consider asking your neighbours to band as well, or organize as a whole block. The more trees that are banded in an area, the more effective it is!

 

Why are the bands removed in May?

 

Trees in our climate hit their peak growing season in the summer months. The bands are removed in order to allow trees to grow unrestricted by the bands. It also allows the bark under the bands to dry out, preventing stress to the tree.

 

What product is used on the tree bands?

 

Tree Band Aid uses a product known as tanglefoot to trap canker moths and other insects on the bands. It is an all natural combination of castor oil, gum rosin and carnauba wax.
