Insecticide

A: Therefore, getting an insecticide with a long residual life is essential to continue killing the insect after the initial application. As a general rule of thumb, most insecticides have a residual life of 60 to 90 days, which can be considered an important maintenance task.

A: Before applying a pesticide (indoors or outdoors), remove children, toys and pets from the area and keep them away until the pesticide has dried or as recommended by the label. Remove or cover food during indoor applications. Don't spray outdoors on windy or rainy days.

A: It's Best to Spray for Bugs in the Morning or Evening. The heat of the early afternoon can interfere with the effectiveness of some pesticides, and can occasionally cause damage to plants when mingled with certain chemicals. Moreover, just as with rain, wind can carry insecticides to places they shouldn't be.

A: An air-purifying respirator equipped with suitable cartridges/canisters is needed for protection against vapors. An air-purifying respirator also can provide protection against dusts/mists if the appropriate filter/cartridge/canister is selected.

A: The speed of kill depends on the amount of insecticide they pick up and their susceptibility to the insecticide. However, even on a freshly sprayed surface, the insects don't pick up much insecticide and it will take minutes or even hours for the insect to die.

A: Avoid applying insecticides when it is raining, as this can prevent the chemical from drying properly. Some products need to be watered after application, which can increase the drying time. Dilution is the solution. When using insecticides, it is important to use them at the lowest percentage needed to work.

A: Cracks and Crevices: Insects can enter the room through cracks and fissures in walls, floors, and furniture, so apply bug spray to these areas.
Window Sills and Door Frames: Spray around window sills, door frames, and other access points into the room where insects can enter.

A: As a rule of thumb, washing with water reduces dirt, germs, and pesticide residues remaining on fresh fruit and vegetable surfaces. Washing and rubbing produce under running water is better than dunking it.

A: Apply pesticides during the cooler part of the day, such as the early morning or evening. Treatments made in the early morning allow foliage to dry before temperatures reach 85–90°F. Take special precautions when using pesticides containing oil.

A: Broad-spectrum insecticides are effective against all insects, even the good ones. Other insecticides target certain insects. Using a targeted insecticide minimizes the risk to beneficial or non-target insects. Some insecticides work immediately to kill insects while others may need some time to take effect.

A: Mix a pesticide and water in the proportions specified on the label. When filling the sprayer with water, do not place the end of the garden hose into the sprayer. Instead, leave an air gap between the top of the sprayer and the hose nozzle, or fill the sprayer with water from a bucket.
