If you grow citrus and/or grapefruit, you should be taking the following precautions.
Be careful when you spray citrus pests with your sprayer sprayer or watering hose.
Many sprayers don’t allow you to set your spray nozzle at an angle, which makes sprayer spraying dangerous.
Make sure your spray canister has a lid to prevent it from getting sucked into your garden.
If you use a citrus or grapefruit pest control kit, keep a list of the items you use to spray citrus and how they interact with each other.
Use a pest sprayer when you’re growing citrus.
Use the sprayer for citrus as a way to get rid of pests before they get to your crops.
If citrus is invasive, make sure you spray it where it will most likely become invasive.
If your citrus or your grapefruit trees are in close proximity, consider planting a small fence or gate between them.
The barrier should be tall enough to allow the pests to pass through safely.
Keep a list for yourself of citrus pests you can spray.
It can be very helpful to keep a journal of where you’ve sprayed citrus and where you can find the pests in the future.
Keep your citrus plants in good health and well watered.
Avoid water problems during the first few months of citrus growing.
If a citrus tree is damaged or dies, the pests can survive and reproduce in a tree.
The tree will recover when it is harvested and will have a new seed.
If an insect eats your citrus, it will take it up and pass it to its next meal.
The insect will then pass it on to its offspring.
This cycle repeats until the next citrus fruit.
If the pests are resistant to one or more herbicides, then consider using a chemical repellent to kill them.
If one or both of your citrus pests are able to spread, make a plan to kill both of them in one season.
If both of the pests spread, you’ll need to spray your citrus fruit again.
If pests are killed and your citrus crop is healthy, then you can return to spraying citrus fruit every spring.
It’s not always clear how much time each insect takes to hatch and how quickly it can spread.
It is also not always obvious which species of citrus fruit are susceptible to citrus pests.
So, you may need to wait several years to see a big improvement in your citrus crops.
