Permanently getting rid of mites in a garden requires spraying preventatively for pests even when we don't have a problem, it's a pretty basic IPM strategy.
If your only using one pesticide over and over again such as forbid (even if it appears they are permanently gone)you are artificially selecting for mites with a resistance to forbid . The more you keep applying it the larger the population of mites with the resistant gene becomes until the pesticide no longer works at all.
I'm not certain as to which pesticide applicator course you took if it advised spraying chemicals without seeing the pests that you are targeting. Here are the six elements of IMP (Integrated Pest Management)
- Prevention
- Identification (pests and beneficials)
- Monitoring of the populations (on going basis)
- Using injury/action thresholds to determine the appropriate time for treatment
- Using treatments
- Evaluating success
Also, if you have a reoccurring pest problem you may want to entertain the idea that your plants aren't as healthy as they could be. Remember, ounce of prevention is worth pounds in the end, lol.
