Houseplants bring the outdoors indoors and refresh a room with their color and life. Houseplant care is dependent on light, water, soil, fertilizer and pest control. Often houseplants come with unwanted guests in the form of hitchhiking insects. A day out in the sun out-of-doors can mean an infestation brought indoors. Insects in the home are unsavory and unhygienic, plus they can ruin the health of your plant. Interior insecticides come in many application mediums from spray to dust. Granular insecticides often have a time-release feature so that they have residual impact and are usually systemic.
Insecticide granules are just the dried form of the product to be applied. They require an inactive ingredient, called a carrier, which can be pecan shells, clay, corn cobs or other materials. The active ingredient is injected into the carrier.This enables the granules to be spread or worked into soil. As soon as they have been properly applied they release the active ingredient. Granular insecticides are more frequently misused than other forms. Care must be taken to read package instructions and follow the application rate.
Dupont has developed Acelepryn, which is an indoor and outdoor insecticide in granular form. For what it's worth, the product label states that if used as directed it "poses no hazards to humans or domestic animals." Do not apply near a fish tank as the poison will kill the fish. It also cannot be applied when the soil is wet, as it disrupts the distribution vertically of the active ingredient. It works on a variety soft-bodied insects.
Bonide Systemic granules contain the active ingredient Imidacloprid. It features a systemic action, which goes into the root system and throughout the plant, to protect from biting insects. The product protects for up to eight weeks and is an easy-to-apply, mess-free product. It protects against mealybugs, scale, thrips, whitefly, fungus and aphids.
Bifenthrin is a synthetic pyrethroid insecticide. It is the active ingredient in Talstar Granules. It contains irregular-sized granules, so complete incorporation and application rate is crucial for the product to work properly. Pyrethroids are synthetically produced insecticides using naturally occurring pyrethrin.They have different pest control abilities and have short active duration. Generally they are only persistent in the plant for a few hours. Bifenthrin gives good control in mealybugs and spider mites.
The active ingredient in Deltagard is Deltamentrin. Deltamentrin is another synthetic pyrethroid with a genesis from a natural insecticide. The pest control is not as good with Deltagard as other pyrethroid synthetics. At best it gives suppression, not true control. Overall, the pyrethroids are safer than other insecticides, but they offer limited insect management.
