Summertime is popular vacation the for many folks, but it certainly is not for insects. It’s also during this time when summer garden pests are most active.
Sorry to say but the spray gun should get lots of use during July if insect damage is to be kept to a minimum.
Let’s consider, some of the insects and related pests which become active during summer months and against which control measures should be applied in July.
Now, some of these pests/insects do not occur in all parts of the country. You’ll need to rely on past experience as well as observation to help select the proper controls or sprays to use.
July… Time For Japanese Beetle Control
In July Japanese beetles (lawn grubs) begin to feed on many kinds of deciduous trees and shrubs, particularly:
- Horse chestnut
When the beetle population is unusually heavy, weekly applications may be necessary.
Midsummer Spider Mite Troubles
Spider mites become particularly troublesome during midsummer dry spells and on plants growing under unfavorable conditions.
The different kinds of mites include red spiders, southern red mite and species named after their principal host like the
- Spruce mite
- Oak mite
- Boxwood mite
- Honey locust mite
The best time to control mites is early June, before they become very numerous.
Unfortunately they are so tiny that they are easily overlooked, and many gardeners don’t know they are abundant until leaves begin to turn yellow.
An easy way to detect mites is to shake some leaves or a small branch vigorously over a sheet of white paper. The pests will be dislodged and can easily be seen against the white background.
Drawing a circle with a lead pencil around each of the tiny “specks” will make their movement even more discernible.
Look for a miticide for home use, or consider essential oils for mite control. Make sure you follow the labeled directions.
Troublesome Plant Scale
By late June and early July, most of the-so-called armored scales, such as oyster-shell scale and euonymous scale on lilac, euonymous and other deciduous trees and shrubs, are no longer in the crawling stage.
They have now settled in their permanent locations along twigs and stems. The ordinary contact insecticides are not very effective against this stationary stage, but a spray like Malathion is usually effective. We also like neem oil to control scale.
The crawler stage of some soft scales like lecaniums and the cottony scales on yew. arborvitae and rhododendron are also controlled with Malathon.
If possible be as environmentally friendly controlling pest as you can. Try going down this pest control path:
- 1st Insecticidal Soap
- 2nd Neem Oil (Our Favorite)
- Last try using Insecticides like Sevin or Malathion – use the right one for the job
Let’s consider insecticides for a moment.
Everyone knows and admits that most insecticides contain toxic materials. Also, these “insecticides” can cause death to humans when they are used under conditions of gross carelessness.
