A popular and simple solution that deters a lot of pests is soapy water. Just spray it on your plants like you would any other type of pest control. Your plants won’t be harmed but it can keep a lot of bugs at bay.
When it comes to bugs in the flower garden, not all of them are harmful. Ladybugs are a good example of a helpful bug because they eat other insects such as mites, whiteflies and aphids that could harm your plants. The Praying Mantis is another creature that is good for a garden. They, like Ladybugs, will eat many garden pest that try to destroy a garden. The insects that are more helpful can either be attracted to a garden by the right plants or bought through a catalogue.
