What Are Sprays For Japanese Beetles?
Sprays are pesticides that are mainly used as surface sprays to kill adult Japanese Beetles. They have limited application for killing eggs or larvae, although some can be used that way.
This video shows their life cycle to help you understand them.
Japanese Beetles do a great deal of their damage during the underground phase of their life cycle but if you kill the adults that emerge in the summer with sufficient surface sprays, you can safely eradicate them, although it may take a couple of seasons to do so.
The main advantage of sprays is their relatively low cost and ease of use. They are premixed and ready to use as soon as they arrive on your doorstep.
If you don’t mind taking a little time and saving a lot of money, sprays are the way to go.
What Are The Different Types of Sprays For Japanese Beetles?
There are two main types of sprays, identified primarily by their mode of delivery or application.
- Premixed and ready to use
These sprays usually come in bottles or containers with a spray handle attached. Some are trigger handles and some have battery-operated wands that spray the pesticide solution.
Either way, they are ready to use without any further effort.
A third option is an aerosol that is premixed and ready to spray.
- Concentrated with garden hose attachments
These sprays are actually concentrated pesticides that have to be diluted with water. They require you to attach a garden hose to the container.
As you press the trigger or squeeze the handle, the water pressure mixes the concentrate as it sprays.
How Do Sprays For Japanese Beetles Work?
Sprays attack only the adult Japanese Beetles. Unless you open the container and pour it on the ground in a drench treatment, they will not affect the eggs or larvae.
The active ingredients have many different modes of action.
Some attack the central nervous system, others affect the muscles in the insects, and still others go after the respiratory system. All of them have to come into contact with the target pest or be ingested by them.
Are Sprays For Japanese Beetles Dangerous To Pets or Children?
Yes and no. Modern pesticides are nowhere near as dangerous as the old-school pesticides that existed prior to the 1960s and 70s.
However, even those weren’t nearly as dangerous as you’ve been led to believe.
That being said, children are more sensitive to chemicals in the environment than adults. Their bodies are still immature and developing.
This is especially true for infants who crawl around on the floor and ground then stick their hands in their mouths.
For most pesticides, we recommend that you keep your children (and pets) out of the treated area until it has completely dried. After that, it should be safe for them to enter.
