Pansies are a colorful addition to any garden. According to the Clemson University Extension, they are one of the most popular garden plants. Unfortunately, a variety of crawling, flying garden pests can damage pansies, including aphids, spider mites, cutworms, pansy worms, slugs and snails. Carefully arranging your garden plants and applying insecticide can help get rid of bugs that compromise the beauty and health of your pansy plants.
Tend to your garden routinely to keep your pansies and other flowers from becoming too wet. Slugs and snails become more of a problem when weather conditions are moist. Remove dead leaves and other damp debris from the garden to deter these pests from damaging your pansies.
Inspect your pansies at night, using a flashlight, to look for slugs and other intruders that prefer the darkness. Examine the undersides of the leaves, a common home to insects that feed on plants. Handpick off any bugs you find.
Stun aphids, spider mites and other insects with a forceful stream of water. Aim a garden hose or spray bottle at the infested pansies, as needed. The force of the water is only a temporary solution, but can prevent some level of damage while you determine an appropriate control method.
Interplant flowering nectar plants with your pansies. According to Clemson University, Queen Anne's lace attracts lacewings and ladybugs, natural predators of several of the bugs that can damage pansies.
Spray your pansies with insecticide soaps or pesticides. Use pyrethroids to kill aphids, and fenbutatin oxide to control spider mites. Spray pesticides and soaps again within a few days of the first application to ensure proper control.
Set slug baits that contain metaldehyde. The University of Georgia Cooperative Extension explains that setting slug baits at night in a damp area at ground level is the most effective way to control slugs through chemical means.
