10 Best Insect Killer For Lawns Safe For Pets – (Reviews in 2022)

Most fur parents know the list of responsibilities on their shoulders the moment a pet becomes a part of their family. It includes providing a safe environment for them to play around. So, many gardeners who have pets are more conscious of selecting the best insect killer for lawns safe for pets since pet care and pest control don’t intertwine at certain levels.  

There have been decades of studies in the agriculture industry about the impact of synthetic chemicals on the environment. One of the most controversial across the pesticide industry is RoundUp which uses glyphosate to control weeds and pests.


The Health Risks of Chemical Pesticides To Animal And Human Health

Monsanto, the RoundUp manufacturer, has received multiple lawsuits due to the potential carcinogenic effects of glyphosate that has caused Hodgkin’s lymphoma to a lot of farmers. In 2015, World Health Organization’s International Agency for Research on Cancer (IARC) stated that the pesticide is probably carcinogenic. However, until it is not ruled out to be as such due to an ongoing debate between two conflicting factors, scientific and corporate matters.

If such pesticides can cause health risks when ingested or inhaled, what more would be its impact on the furry pets who run in treated lawns. Sometimes, they even occasionally chew grass out of a biological habit. What’s toxic to humans is also toxic to pets. 

According to a pet poisoning rescue organization, Pet Poison Helpline, pesticides may cause dogs and cats to experience the following after being exposed to toxic pesticides:

  • Excessive drooling
  • Nausea
  • Vomiting
  • Diarrhea
  • Skin rashes
  • Respiratory problems

The good thing is there are now environment-conscious organizations that manufacture insect killers for lawns safe for pets, kids, and the environment.

In this post, we listed several insect killers for lawns that have been tried and tested by fur parents to use on their lawns.

3. Summit Chemical Co. 30OZ Mosquito Bits

Summit Chemical Co. 30OZ Mosquito Bits Review

If you’re looking forward to discovering a pet-friendly insecticide that works wonders on lawns, Summit Chemical’s Mosquito Bits must be the one. It is a quick-acting insecticide made of corn cob bits coated with Bt or Bacillus thuringiensis solution. 

Bacillus thuringiensis is a biological insecticide derived from natural soil bacteria that attacks the digestive system of insects. It is safe around kids and pets since the toxins found in Bt are selectively toxic to insects. The manufacturer only claims that it can control mosquitoes and gnats. However, gardeners also found it effective in managing other lawn insects like fruit worms and worms. 

The manufacturer is proud that this insecticide is EPA-registered in 50 states. It is among the holy grails of gardeners who want to keep their dogs and cats safe from running across treated lawns. The bits are sprinkled in lawns and swampy areas to help control the mosquito population every two weeks. 

Aside from mosquitoes, this insecticide can also deal with the annoying fungus gnats that have been a headache for most gardeners. You pace the bits on top of pots and flower beds to manage the population of gnats. In some cases, gardeners also mix the bits with the potting soil to improve its control on soil-borne pests.  

The pattern of pest control using Mosquito Bits is that it is ingested by larvae and insects. After several hours, the Bt will paralyze the digestive system of the insects which will cause them to die out of starvation. As for the larvae of mosquitoes, they will no longer develop into flying blood-sucking insects. 

Gardeners love discovering this insecticide since it allows them to enjoy bug-free nights with their pets running outdoors.

It also saved gardeners a ton of money in hiring pest control services to deal with pesky gnats and mosquitoes. They also appreciate how a bag of Mosquito Bits can cover 3 acres of lawn. It may cost more than your usual insecticide but it’s definitely worth the price.

8. Safer Diatomaceous Earth-Bed Bug Flea, Ant, Crawling Insect Killer 

Safer Diatomaceous Earth-Bed Bug Flea, Ant, Crawling Insect Killer

Practices & Techniques: Other insect killers for lawns that are safe for pets

Aside from insect killers for lawns that are safe for pets, there are also other ways for pest management in your lawn. These include:

(1) Essential Oils: Though some of the insecticides already use essential oils, some are not yet explored to be added to mainstream insecticides. These include:

  • Lavender: An essential oil known for its calming effect on the human body is good pest control for ants. The smell deters the ants and keeps them away without harming them. 
  • Tea tree: An essential oil known for calming skin issues like acne and pimples is also a common ingredient in pet shampoos. It is an effective solution for fleas and ticks in cats and dogs. 
  • Pine: An essential oil known for its earthy scent can help repel mosquitoes. 

(2) Predatory insects: If you want to allow nature to take over in keeping your lawn bug-free, you may add some insect predators to your lawn. Ladybug, in particular, is fond of eating aphids. Other animals that eat common lawn insects are:

  • Praying mantis: mosquitoes
  • Lacewings: mites
  • Parasitic wasp: caterpillars

What Are The Substances in Pesticides That Can Harm Cats and Dogs?

Before you head on and buy pesticides in the market, it’s best to identify the substances that are toxic to pets. So, some sly manufacturers won’t trick you into buying their products even if they indicate that they are safe for pets.

The toxic substances in pesticides are as follows:

Pyrethrins or Permethrin

Pyrethrin is a natural insecticide derived from chrysanthemum flowers. Though it is organic, cats are sensitive to it more than dogs. Permethrin is the synthetic version of pyrethrin that can cause hyperesthesia, generalized tremors, muscle fasciculations, hyperthermia, and seizures in cats.

Permethrin and pyrethrin, however, are effective in getting rid of ticks and fleas as a spot-on treatment for dogs and insecticide for some plants. Common brands that permethrin are:

Pyrethroids

Pyrethroids are the synthetic version of pyrethrin which includes two types. Type 1 pyrethroids include pyrethrin I, allethrin, tetramethrin, kadethrin, resmethrin, phenothrin, and permethrin. Type 2 pyrethroids include cyfluthrin, cypermethrin, fenpropathrin, deltamethrin, cyphenothrin, fenvalerate, and fluvalinate.

Insecticides that contain any of these substances in increased dosage can be harmful to dogs and cats and may cause seizures and neurological problems.

Common insecticides that contain pyrethroids are as follows: 

Organophosphates

Organophosphates are substances derived from phosphorus acid. One of the most popular forms of this pesticide is malathion. Another one is disulfoton which is a systemic insecticide that is absorbed by plants and kills pests through ingestion of leaves or sap. Dogs are particularly attracted to disulfoton mixed in fertilizers and other insecticides in plants.

Pesticides under organophosphates are one of the most toxic pesticides for dogs and cats which can cause excessive drooling, vomiting, diarrhea, and urination. Too much ingestion of these pesticides can cause pets to vomit, and defecate blood. Have seizures, muscle tremors, and coma.

Lawn insecticides under this category include:

Carbamates

Carbamate insecticides can cause the same effects as organophosphates in dogs and cats. Accidental ingestion of carbamate pesticides causes seizures and respiratory problems in your pets.

Insecticides under this category include aldicarb, carbaryl, methomyl, and propoxur. It is the insecticide used by thieves with malicious intent to kill household pets in some countries like Brazil. 

Brands with carbamates are as follows: 

Deet

Deet is a common substance found in natural insect repellants for kids. However, it is not good for your dogs and cats.

According to the American Society for the Prevention of Cruelty to Animals, inhalation of deet in pets may cause airway inflammation and dyspnea while accidental contact to the eyes of deet may cause conjunctivitis, scleritis, blepharospasm, epiphora, lethargy/depression, uveitis, and corneal ulceration in pets.

D-Limonene

D-Limonene is a substance found in citrus fruits that are used as a herbicide and an insecticide.

In moderation, it can help get rid of fleas and ticks. However, ingestion of the d-limonene and 5 to 10 times increase in its concentration excessive drooling, tremors, lack of coordination, and critical low body temperature in cats while it causes vomiting in dogs.

Final Thoughts

Insect killers for lawns safe for pests use plant-based materials and do not contain any deet or pyrethrins. Due to the efforts of independent organic companies to provide a safer alternative to chemical insecticides, there are now several brands that offer pet-friendly lawn insect killers.
