Utilizing traps is an effective way to monitor and control insect populations. Here are two beneficial traps:
Sticky Traps
These brightly colored sticky traps attract flying insects like whiteflies and fungus gnats. Place them around the garden to catch and monitor insect populations.
Beer Traps
This trap is excellent for controlling slugs and snails. Bury a container up to its rim in the soil and fill it with beer. The smell attracts these pests, leading them to drown.
7. Chemical Control as a Last Resort
While it’s best to keep chemistry out of your garden as much as possible, there may be instances where you’ll need to use chemical control.
Insecticidal Soaps
Insecticidal soap is safe for most plants and can control soft-bodied insects like aphids and spider mites without harming beneficial insects when used appropriately.
Pyrethrin
Derived from the chrysanthemum flower, pyrethrin is an effective insecticide that acts quickly against a range of pests. However, because it can harm beneficial insects, it should only be used when necessary and applied in the evening.
