Hello. We have a perimeter of probably 70 arborvitae trees that have recently started dying in one patch (back right in photo). Another patch has recently started dying (left in other photo). I found the beetle in the attached pic in a small gall under the bark of one of the trees in the new patch. I’m looking for advice on how to save the remaining trees. Is this a pine bark beetle? Any help to save our trees would be immensely appreciated!!
For highest reach, get one of our NO PUMP SPRAYERS. This vunique sprayer is simple yet very good, easy to use and one of our “favs” for applying insecticides to your homes exterior and landscape (its too powerful for use inside).
Ideally suited for reaching heights of 40+ feet, it has no moving parts other than the valve you hold for spraying and the adjustable brass “bullet” nozzle.
This sprayer is essentially a tank that can hold water, chemical and up to 130 psi of air. The top lid has a clamp and rubber gasket that seats on the “inside” of the sprayer so as you fill it with air, the seal will naturally remain in place, nice and tight.
The top has 3 “ports” (pic below). The port to the far left is used to fill the tank with air. Using any electric air pump (the kind you would use the fill tires on your car), you can safely pressurize this sprayer up to 80 psi. The tank is rated for up to 130 lbs but the relief valve will only allow you to fill it to 80-90 psi before it starts to release. This happens as a safety precautionary action.
For normal use around the home, 50-60 psi should be enough for you empty the liquid from the 2.5 gallon tank assuming you only add 1 gallon of mixed product. True, the sprayer can “hold” 2.5 gallons of liquid but you need room for the air. Our tests show that 50-60 psi will pump out an entire gallon of spray allowing you to reach 25-30 feet heights.
For reaching 40+ feet or higher targets, pressurize the sprayer to 80 psi and again, mix up only what you plan on using and no more than 1 gallon of mixed solution at one time so the tank has enough room left to store all the needed “air”. One charge of 80 psi is enough to get the entire mixture to spray out so you don’t have to be concerned about constantly recharging.
The 5 GALLON NO PUMP can hold over 2 gallons of mixed material and can perform equally as well.
Remember, YOU WILL NEED AN AIR COMPRESSOR POWERFUL ENOUGH TO FILL THIS SPRAYER!! WE RECOMMEND ONE THAT CAN DO AT LEAST 100 PSI.
