Our Overall #1 Rated Pick

(updated as of 04/13/2020)

  • The active ingredient is Spiromesifen
  • Spray the top of the leaves
  • Translaminar properties

Forbid uses the active ingredient Spiromesifen, at 45.2%.  When you spray the top of the leaf, the pesticide moves through the leaf to the bottom where the spider mites are.  This makes Forbid unique among all other pesticides.

This makes it easier to apply than other pesticides because you don’t have to spray the undersides of leaves.  It has a quick knockdown for adult spider mites, plus a long-term residual impact. It will also kill whiteflies as easily as it will kill spider mites.

The ease of use and fast action make this our top choice for killing spider mites.

What Are Sprays for Spider Mites?

A spray for spider mites is a method of chemical control as opposed to using a biological control with beneficial insects such as ladybugs, thrips, and the occasional lacewing who are all natural predators who eat spider mites.  Predatory mites or other natural enemies are not a spray.

Those methods have their place and we recommend them in certain situations, but not here.  We’re also not going to talk about neem oil, rosemary oil, or other methods of non-toxic pest control such as an insecticidal soap.

The chemical pest management of mite populations will focus on using a miticide to eliminate an infestation.  A miticide is a pesticide specifically designed to kill mites because they are generally immune or highly resistant to ordinary pesticides.

For more information on handling your spider mite situation, check out the video below.

How Do Sprays for Spider Mites Work?

Although each miticide will have a different mode of action depending on what active ingredient is being used, the commonality is that it is designed to overcome the rapid speed of a spider mite’s life cycle.

Because miticides are designed to kill mites, they won’t harm other beneficial insects, such as the ones who eat spider mites.  Not all insects are harmful and many of the repellents and other methods of pest control, like diatomaceous earth, will kill them.

Are Sprays for Spider Mites Effective?

Yes.  As long as you use them correctly and according to the instructions on the label.  Pesticide labels are regulated by the EPA, resulting in the common saying in the pest control industry that the label is the law, and it absolutely is.

That being said, as long as you use the right equipment, mix the pesticide correctly, and apply it according to the directions, you’ll get professional results you’ll be proud of.

How To Use A Spray for Spider Mites

Mix the miticide in a heavy-duty pump-up sprayer.  Set it to a fine spray.  Hold the tip of the wand 18-24 inches away from the target and spray.  Except when you’re using Forbid 4F, you’ll have to get under the leaves and spray up to get the bottom of them.

Spray to the point the leaves are damp but not soaking wet.  The leaves shouldn’t be dripping chemicals. If they are, you’re moving the wand too slow.  Speed it up some and you’ll get better results.

Are Sprays for Spider Mites Safe Around My Pets And Children?

No.  Children are often at greater risk from pesticides than adults are due to the difference in their bodies from adults.

They are closer to the ground because of their size, they have a greater surface area to weight ratio, their respiration is faster (meaning they breathe in fumes faster), and toddlers and below often put things in their mouth, exposing them to toxins.

Warning

Miticides are not safe for use around children and pets. Please make sure to use extreme caution when using these products.

Miticides are stronger and faster acting than ordinary pesticides, so the risks are commensurately greater.  The same logic applies to pets. Plus, cats and dogs are often sensitive to toxins that leave human beings untouched.

Keep children and pets out of the treatment area while you’re spraying and for several hours afterward until the chemicals are completely dry.

  • The active ingredient is Spiromesifen
  • Spray the top of the leaves
  • Translaminar properties

This means when you spray the top of the leaf, the pesticide moves through the leaf to the bottom where the spider mites are.  This makes Forbid unique among all other pesticides and makes it easier to apply because you don’t have to spray under the leaves.

It is versatile and has a broad spectrum application to numerous plants and insects.  It works effectively on foliage and flowers and has some translaminar properties which result in rapid movement through the entire leaf.

It’s an effective spider mite killer throughout their entire life cycle.  It gives you a quick knockdown when spider mites come into physical contact with it and provides residual control for up to 28 days after application.

It is gentle on beneficial insects and predacious mites.  This makes it a good choice for use in what the EPA refers to as an Integrated Pest Management (IPM) program.  However, it should not be used on fruit trees when they go into bloom.

  • 28-day residual impactQuick knockdown

Cons

It kills over 200 different kinds of crop-damaging insects, such as beetles, mites (including spider mites), roaches, and ants of all kinds.  However, because it is a broad-spectrum insecticide, it will kill many beneficial insects as well as harmful ones.

Pros

  • Can be used up to the day of harvest
  • Can be used on vegetable crops
  • Kills over 200 different insects

Cons

  • Kills beneficial insects

On pets and livestock, it will kill fleas, flies, gnats, lice, mosquitoes, and spider mites.  It also kills ordinary pests such as ants, roaches, silverfish, spiders
