Northern Pine Weevil can go unnoticed for long periods. The insect pest usually hides all day long and feeds at night. Oftentimes, heavy infestations of Northern Pine Weevil happen in September. Trees affected by the bug should be sprayed by methoxychlor. The spray is applied to the foliage.

Controlling the insect pest is no easy task. Trees attacked by the bug needs to be sprayed. The spraying needs to be done in middle July and then needs to be repeated in September.

Those Toronto’s residents who have birches or alders on their properties may need to deal with such an insect pest as Birch Skeletonizer. This pest leaves eggs on tree’s leaves. When larvae appears it starts feeding on leaves. If left untreated, larval mines may destroy leaves on a tree. During the heavy infestations leaves on a tree become completely skeletonized.
