As mentioned in a previous article, some insect pests tend to show up the same time every year. Some years these pests may be worse than others. This year, we are seeing a couple of pests make their appearance in July.

Last week, I started noticing some webbing on the ends of branches of certain trees. These are fall webworms and can be found primarily on cherry, sour wood and persimmon trees. It looks as though this caterpillar population is going to be large this year.

Fall webworms will not affect the health of large trees, although the webbing may be unsightly. They can, however, defoliate young trees which may affect the tree health. Removing the webbing from the tree or spraying with an insecticide should take care of the problem.

Another pest that started showing up a couple of weeks ago is the squash-vine-borers-2squash vine borer. This caterpillar burrows into the squash stem and feeds on the inside of the plant. The plant will begin to wilt, turn yellow and eventually will die.

If you do a little investigating, you might be able to find where the borer entered the plant. In which case you can remove the pest by hand and you might be able to salvage the plant. Insecticides are not recommended since they do not come into contact with the borer inside the plant.

I am also seeing dragon flies hovering over car hoods. These dragon flies have mistakenly thought your shiny paint job was water, which is where they normally lay their eggs. There is not anything you can do, but be aware, egg laying may damage the paint on your vehicle.
