Apply pesticides frequently enough. Application frequency depends on the residual activity (persistence) of a given pesticide and temperature, as insect and mite pest development (life cycle: egg to adult) increases under higher temperatures, consequently requiring more frequent applications.
How Often to Mist Houseplants. Houseplants can be misted about once a week or more during colder seasons when humidity levels are lower. However, you should scale back your misting schedule if you notice signs of disease, like leaf spot, discolored leaves, or wilting of the new growth, says Hancock.
You might think more of the spray will make it more deadly for the pests, but that's not true. It's already poisonous enough, the best thing you can do is leave the product do its job. Once you're done spraying, do not clean the sprayed area! That's it.
Generally, the population of visible pests will decrease within the first 2 weeks, then over the following weeks, the last of them will be affected by the gel and residual sprays.
You can typically spray your plants with soapy water once a week. This frequency helps control pests without harming the plants. However, consider these factors:
Dishwashing liquids are primarily designed to dissolve grease from dishes and clean clothes, not to kill insects. Dish detergents may dissolve the protective waxes on the plant leaves.

Give It Time
It's entirely normal to see an increase in pest activity immediately after the treatment, but this should gradually decrease as the treatment takes full effect. In the meantime, resist the urge to use DIY pest control solutions.
Let's recap when to eradicate bugs
Early morning and evening are the optimal times to apply the spray, allowing you to take advantage of cooler temperatures and higher pest activity. Avoid spraying during the midday heat, and always consider weather conditions before applying pest control treatments.
Chlorpyrifos has a soil half-life of 11-140 days; persistence increases in more acidic soils; “residues” (unspecified levels) occur on plant surfaces for 10-14 days after application. Carbaryl has a soil half-life of 7-28 days; plant surface residues (unspecified levels) usually last less than 14 days.
Insecticide plant injury, or actually any kind of chemical plant injury, is known as phytotoxicity. Herbaceous plants are most vulnerable to pesticides. Woody plants tolerate them better, but new fresh growth can be damaged by these chemicals.
Bug spray should be used carefully, and you shouldn't need to apply it more than once per day. “You really want to control the amount of bug spray you use. Put it only in areas where you think you need it and not in excessive amounts,” Chon says. The most well-known bug spray ingredient is DEET.
Bugs hate the smells associated with repellency, such as lavender, citronella, vinegar, peppermint, and geranium. These oils are considered a natural way of driving away bugs from your home without harming you, your family, and other animals.
Cacti, succulents, fiddle leaf fig (Ficus Lyrata), and other plants that prefer dry environments are among them. Although they prefer humidity, watering fuzzy-leaved plants like African violets and piggyback plants (Tolmiea menziesii) is not recommended since the water droplets will mark the surface of the leaves.
Misting can provide several benefits for certain types of indoor plants. For one, it can help increase the humidity level around your plant which can be beneficial for those that thrive in humid conditions. This is particularly useful during winter months when indoor air tends to be drier due to heating systems.
Avoid creating a routine of watering at the same time every day or every week. Instead, get in the habit of paying attention to the soil and the weather so you can water when the plants really need it. Containers need frequent watering.
As for the repellent, it usually lasts six to eight hours. If it hasn't worn off by bedtime, you'll want to wash it off with soap and water, as it can be irritating if left on overnight.
Vinegar spray
Simply mix one cup of white vinegar, at Walmart, with three cups of water. You can also add half a teaspoon of dishwashing soap to help the solution adhere. Shake thoroughly and apply to the affected areas. The acetic acid in the vinegar will treat a wide range of garden pests but it requires contact.
For most species, however, the activity generally peaks during the dusk hours. This means that if you're heading out in the evenings, especially near wooded areas, standing water, or bogs, it's wise to be extra vigilant and well-prepared with insect repellent.
Don't stress if you do see bugs after treatment, some of them, especially cockroaches will survive the treatment, or will take a week or two to die.
While there's no recommended amount of bug spray to use, experts recommend using enough to create a thin layer of protection on your clothes and exposed skin. But do not use any more than necessary.
Rain just before or after an application does not have a major effect on the success of the treatment. The products we use are oil based, and are not “washed off” by the rain. In fact, we are not treating foliage at all, but spraying in the air while mosquitoes are flying, impacting them at that time.
Spray the plants with soapy water every few days, especially on the underside of the leaves. One tablespoon of dish soap or castile soap per gallon of water is enough. Spray with dish soap plus cayenne pepper and/or neem oil. Neem oil sprays are available at most garden centers.
How often should you apply neem oil for plants? You should apply it around one or two times a week to get the acute infestation under control. If you just want to prevent your plants from any pests, you can use the neem oil every 7- to 14 days.
I yoink the plant out of its pot/substrate right away outside if I can. Drown that plant in a container with water and a few drops of either neem, insecticidal soap or peppermint Castile soap for about 10-15 minutes. I do dip the roots, but don't submerge them. And repot after the treatment.
