Other Pests and Weeds: Deciding on Treatment
Mechanical Controls
Hand Pulling weeds before they establish deep roots or seeds.
Spray water on aphids, and use sticky bands in winter
Biological controls
Take advantage of friendly insects, such as ladybugs. Birds and snakes also ward off slugs.
Before you choose to control aphids, and insect parasitic nematodes to control root weevil and
European Chafer Beetle. Before buying biological controls, learn about them and how they can
best work for you.
Chemical Controls (most pesticides)
Observe municipal regulations. Many municipalities have passed by-laws to protect our eco
-systems. Check with your municipality first. Many municipalities have passed by-laws .
Pesticides, for cosmetic purposes are usually banned and in any event should be seen as
short-term and use only once and only in the affected area.
Even a relatively safe product for humans, such as insecticidal soap spray, will still kill lady-
bugs and other beneficial insects. Pesticides may also pollute streams and harm fish
when the rain washes them off your yard into ditches.
Friend or Foe?
Not all insects are pests!
Some insects are not pests and many insects do no harm. Correctly identify the pest. Euro-
pean Chafer Beetles, a new pest to the area, doesn’t really damage the grass. But the
skunks, racoons, and birds who love to eat these beetles can make your lawn look like it has
been recently rototilled.
Repair the damaged lawn and then encour-
age deep-rooted healthy lawn growth. If the
lawn is dense, the adult beetles are not able
to lay eggs in it. The life of an adult beetle is
short and they emerge for only a few weeks
in the summer.
Nematode treatments (a biological not toxic
treatment) applied in late July can combat
the problem without harming the eco-
system.
