What Are Pet Safe Grub Killers?

Pet safe grub killers are a method of pest control used against a grub infestation that will kill grubs without endangering your pets.

It is a grub killer that won’t kill pets. More accurately though, it’s a grub killer that won’t harm your pets.

We say this because very few grub control methods are strong enough to kill mammals. Some of them can make your pets ill if they’re used improperly but are completely pet safe when used according to the instructions on the label.

The safest grub killers to use around your pets are the all-natural methods that use beneficial nematodes, milky spores, or essential oils.

There aren’t any health issues with those remedies. They can address your grub problem without endangering your pets.

The next safest are the granular methods, using granules that have to be “watered in” to take effect. Once the grass has completely dried, it becomes safe for your pets and children to enter the treated area.

What Are The Different Types of Pet Safe Grub Killers?

Grub worm killers are specialized pesticides for killing grub worms. Common grub worms are the European chafer, June beetles, and Japanese beetles.

The adult beetles live above ground. Grub damage to plant roots is caused underground by the larvae.

Therefore, an infestation of grub worms has to use a control method that reaches them where they live. Any grub treatment has to deliver the active ingredient down into the ground, usually by heavy watering. Here are some active ingredients you can use.

  • Beneficial Nematodes: microscopic worms that live in warm moist soil, which limits the time and area where they can be used. Common nematodes are Steinernema feltiae, Heterohabditis bacteriophora, and Steinernema carpocapsae.

They are completely harmless to pets, children, and adults.

  • Milky Spore: a bacterium effective at controlling only Japanese beetle grubs. It will not kill any other lawn grubs, such as armyworms. It also takes several to be effective but it completely harmless to pets, children, and adults.

Milky spores and beneficial nematodes are 100% pet safe but their temperature and soil limitations can make them problematic if you’re in a cold or dry climate.

  • Azadirachtin: a natural extract from Neem trees, this natural pesticide has been used for centuries. Concentrated neem oil can be hazardous to cats. Clarified neem oil doesn’t contain azadirachtin and so it is completely safe, but also useless as a pesticide.
  • Chlorantraniloprole: a broad-spectrum insecticide that causes muscular contractions in insects, leading to death. It has low toxicity to mammals when applied. After watering in, the toxicity is reduced nearly to zero.
  • Trichlorfon: also known as Dylox™ is an organophosphate, a class of highly effective insecticides also known to be toxic to mammals, including cats and dogs. It must be thoroughly watered in and the yard allowed to dry before it is safe.
  • Gamma-cyhalothrin: a microencapsulated pyrethroid that is toxic to fish and shouldn’t be allowed to run off into streams or rivers. Once it is dry, it is safe for your pets.

What Makes A Grub Killer Pet Friendly?

Several things stand out. Let’s take them one at a time.

  • First is the ease of use. If it’s so complicated you feel you need a degree in rocket science to figure it out or it takes all day to apply it, it’ll probably never get used.
  • Secondly, you should look at how well your pet is protected from harm. Most grub killers exist somewhere on a sliding scale of pet-friendliness. As long as the safe zone arrives fairly quickly after application, it can be considered safe to use around your pets.
  • Third, it shouldn’t break the bank. When you’re treating a yard or field, you need to break it down to price per square foot. A $25 bag that only covers 2,000 square feet when you’ve got a 20,000 square foot yard, is going to be too expensive.

Are Regular Grub Killers Unsafe For Dogs And Cats?

The only honest answer is yes and no.

As a general rule, cats are more sensitive to pesticides than dogs. Any label that warns about toxicity to mammals (your pets are mammals) should be used exactly the way the label advises, including wait times before entering the treated area.

Regular grub killers use pesticides that have varying degrees of toxicity, therefore your pets run the risk of a reaction if they are allowed re-entry too early. Follow the instructions on the label and you shouldn’t have any problems with your pets.

NaturesGoodGuys Beneficial Nematodes

Beneficial nematodes are shipped live, more than 30 million of them in each package, and they attack more than 200 species of soil pests and insects.

They actively hunt for insect larvae, enter their bodily openings, and attack them from the inside.

Gabriel Organics Milky Spores

Another all-natural grub and insect killer are milky spores. They’re completely safe for your pets and won’t hurt any beneficial insects, fish, or plants.

They only attack the Japanese beetle larvae. Adult Japanese beetles and other grub species remain untouched.

Milky spores require a warm, moist environment and take several years to show their effects. They continue providing benefits for several years after that. This is a long-term solution that works well within its parameters.

Each 20-pound bag covers 7,000 square feet and you’ll need a hand spreader or yard spreader to spread it.

The Good And The Bad

  • Easy to use
  • Covers 7,000 square feet
  • Long-term solution lasts for several years
  • It won’t harm other insects, animals, fish, or birds
  • Requires a hand or yard spreader
  • Only targets Japanese beetle grubs

Cold Pressed Neem Seed Oil

This is 100% cold-pressed neem oil from neem seeds. The active ingredient is Azadirachtin, from neem oil. Neem oil acts to reduce insect feeding.

It also creates a hormonal imbalance that makes it difficult for the grubs to lay eggs.

Mix 2-3 teaspoons with 32 ounces of water in a 32-ounce spray bottle then spray it on the yard early in the morning or later in the evening to prevent the sun from burning it off. If you maintain the mixing ratio you can also use hand-held or backpack sprayers.

The concentrate can cause irritation to your skin or eyes but once it is diluted it is safe for you and your pets. You’ll need to reapply it every couple of weeks.

The Good And The Bad

  • Easy to use
  • No chemicals
  • All-natural grub killer
  • Needs to be reapplied frequently
  • The concentrate may cause eye or skin irritation

Scotts GrubEx1 – Grub Killer for Lawns

Scotts GrubEx1 is an effective grub killer. The active ingredient is Chlorantraniliprole. Just under three pounds of granules are required per 1000 square feet of lawn. The granules need to be watered in with an inch of water to activate them.

You’ll need a hand spreader or a yard spreader to spread the granules. Set the spreader on a medium setting and walk back and forth at a normal walking speed.

Once you’ve covered the entire yard, water in the granules, then let the yard dry completely.

GrubEx will kill grubs before they cause damage to grass roots, then grub control all season long to keep them from coming back. It kills white grubs, sod webworms, Japanese beetle larvae, and more.

The Good And The Bad

  • It is easy to use
  • Lasts for an entire summer season
  • It won’t harm soil bacteria or earthworms
  • Uses less than three pounds per 1000 square feet
  • Can be hazardous when it is fresh or wet

BioAdvanced 24-Hr Grub Control

Labeled as a 24-hour-grub-killer, this grub killer from Bayer uses Trichlorfon (Dylox™) as the active ingredient. It’s actually a 24-hour-grub-killer-plus because it also kills armyworms, ants, cutworms, ticks, earwigs, grasshoppers, millipedes, and more.

Each 10-pound bag will cover 5,000 square feet using a hand spreader or yard spreader.

After covering the yard with the granules, water them in with about an inch of water, then allow the yard time to dry before letting your pets or children on it.

Although Bayer Advanced is a well-known name, this product may require a second application in the fall to maintain its effectiveness.

The Good And The Bad

  • Manufactured by Bayer
  • It works within 24-hours
  • It lasts for several months
  • 10-pound bag covers 5000 square feet
  • Kills many other insects as well as grubs
  • A second application in the fall is usually required
  • Has to completely dry before allowing pets and children on it

Spectracide Triazicide Insect Killer (Honorable Mention)

This grub killer uses Gamma-cyhalothrin as the active ingredient. This “regular grub killer” kills many different insects and has to be watered in after application in order to kill grubs.

It’s not as effective or long-lasting as the others on our list but it does work and we thought it deserved an honorable mention.
