Got some Junipers, Japanese maple, pines, evergreens, arborvitae, and on top of that we have bag worms. Bag worms feed on over 100 species of plants, and if you get one or two of these on your evergreens you’ve got a serious problem.
Because in the fall; they populate and, lay 1,000 eggs inside the bag. And those eggs will hatch in early summer and cover this plant with bad guys. Itty-bitty, nasty, hungry, little bag worms.
They haven’t hatched on this plant yet, but we found them on another. Most of the time we notice bag worms in our landscape because they’ve eaten up our Junipers or Arborvitae. The fact is they’re very tiny when they first hatch and they hatch early in June. And they’re very small like this one here. This is a case of an ounce of prevention being worth a pound of cure. If we wait until we see inch long bag worms devouring our evergreens in August, we’ve probably waited too long.
A better way to handle the problem is to get the bag worms when they’re young. In June or July we can apply BT; Sevin; or, Cygon to our evergreens and control the evergreen bag worm before he’s taken control of our landscape.
Bag Worms…
- Feed on over 100 species of plants
- Populate in the fall and lay 100 eggs inside the bag
- Are very tiny when they hatch
- Hatch in early June
- Are best eradicated in June or July by applying BT, Sevin or Cygon to your evergreen
