An insecticide is a pesticide that kills pests such as ants, fleas, ticks, and mosquitoes – but people don’t use them just against bugs anymore; they also target pesky weeds like dandelions and clover (to name two). Most of these pesticides come in powder form (including those that have been developed to kill lawn pests, such as grubs) but you can also find many liquid treatments.

Benefits of lawn insect killer granules:

  • They provide a barrier that kills insects on contact;
  • They are easy to use because they don’t require mixing with water or soap;
  • Lawn insect killer granules come in an array of different sizes so you can find the right one for your lawn size and pest problem;
  • You can choose from a variety of insect killing granules, including ones that are for specific problem areas;

Some other disadvantages include: 

  • Lawn insect killer granules need to be reapplied after rain events or watering your lawn and this means more maintenance on behalf of the homeowner;
  • They don’t kill all types of pests so if you have a wide range then they may not work well enough on them all. This also includes those pesky ticks;
  • It’s hard to use them in combination with other products because different ingredients react differently together which could lead to unintended consequences like increased toxicity;
  • Lawn insect killer granules take a little while to kill the insects which means that you could get lots of bites before they die off;
  • The last disadvantage is that if not applied correctly, lawn insect killer granules can be toxic for pets and children who come into contact with them or ingest them by mistake;

There are a number of options out there when it comes to choosing the best insect killer granules for your lawn. Some people choose to do nothing and hope for the best but that might not be the wisest decision currently. You never know what kind of pest might be lurking on your property or what they’re bringing into your home! The good news is, you don’t have to worry about it because we are here to help with the ultimate guide on finding the right lawn insect killer granules for sale.

The Buyer’s Guide

Granules or Spray?

A common question is whether to use granules or a spray for dealing with lawn pests. For the most part, both are considered equally effective. If you have pets in your home and worry about them being exposed to pesticides by licking their feet that may have been sprayed outside as they walked through it on their way inside then using granules would be the better choice. 

Granules can also offer more targeted control since many of these contain natural pyrethrin which only affects insects and not animals like dogs who might drink from puddles left after rainstorms where this type of pesticide has washed off into nearby water supplies so it’s best to avoid spraying when possible if there ever was any chance of runoff occurring.

If you are looking for a lawn insect killer that is environment-friendly, consider buying the granules. Insects cannot be killed by ingesting these types of pesticides, and they don’t leave behind residue on your grass like other options do. However, you must water them in well to activate the pesticide’s effects before mowing or walking on it.

Granules are typically the more cost-effective option. They’re also able to be applied at a greater distance, so it’s easier to cover an entire lawn while still maintaining control over where the insecticide is going. This makes them ideal for larger yards or areas with sensitive plants that need protection from pesticides like roses or fruit trees. That said, granular treatments can take days longer than sprays to show results and they don’t last as long because rain washes away the product too quickly. If you have a small yard without any precious landscaping, spraying might be best for you.

Granules can be applied at a greater distance than with spray applications, which means it’s easier to cover an entire lawn while still being able to maintain control over where the insecticide is going. This makes them ideal for larger yards or areas with sensitive plants that need protection from pesticides like roses or fruit trees. That said, granular treatments take days longer than sprays to show results and they don’t last as long because rain washes away the product too quickly.

Insecticide can also be applied as a liquid spray with more limited range than granular products but easier application to difficult-to-reach areas such as tree trunks and around fences where insects may gather unnoticed until too late. Spray any areas where ants are seen soiling foodstuffs left out outdoors; this will keep them from reaching your home again – once they ingest the insecticide, they will die.

If you have a small yard without any precious landscaping (or just want to save some money), spraying might be best for you. Spraying is more expensive in the beginning, but it takes less time to see results.

You also don’t have to worry about rain washing away your product prematurely or having any problem treating plants that are sensitive to pesticides like roses or fruit trees because spray doesn’t touch them directly. If you’re on a budget and/or need immediate relief for an infestation issue, spraying might be best for you.

Chemical or Natural Solution?

Choosing chemical or natural insect killer granules is an important decision. There are pros and cons to each, which we will discuss in detail below. The most common issue with chemicals is that they can result in unintended toxicity if not used correctly, while natural insect killer granules don’t have this issue but may take longer to work.

Here is what you should know before buying a lawn insect killer granule:

  1. Chemical insect killer granules. Chemicals such as organophosphates are effective against many different types of insects at large quantities; however, some people feel more comfortable using these over others because their effects on humans and the environment depend mostly on how it’s applied rather than what type of product it is. One downside for those who prefer them over other types of products is that they can be more expensive than chemical-free options, but they are also highly effective at killing pests;
  2. Natural insect killer granules. These granular products kill insects in a way that is similar to how organic gardening products work – by interfering with the life cycle of their target pest. The most common active ingredient for these types of insect killer granules is pyrethrum flowers which contain compounds that irritate and paralyze an insect’s nervous system when ingested or touched while repelling natural enemies such as ladybugs and other predators. One downside for those who prefer them over other types of products is that it can take longer for this type to get rid of infestations because not all bugs will eat them out on sight so it’s often necessary to reapply them;

Types of pests

There are many different types of pests that can be found in the lawn, including ants and termites. Ants might cause damage to your home by digging up dirt for their nests or even eat food out from under you! Termites will not only chew on wood but also produce a gas known as methane which is dangerous if it builds up inside your house. You may want to find insect killer granules that targets both ant and termite infestations.

To reach any pest type, usually all you need is just one product with the right concentration: 

  • spider repellent; 
  • mole control chemical; 
  • mothball powder; 
  • tick treatment pesticide;

 However, some products work better than others depending on what kind of pest they’re targeting.

Below are a few types and their benefits:

  • Broad-spectrum insecticide granules. These work on all insects, including beetles, earwigs, crickets and ants. Be sure to go with one that has an IGR (Insect Growth Regulator) included as well to kill off any larvae eggs or pupae. The tradeoff for these being so effective is they can’t be used near water because they’re not safe for aquatic lifeforms like fish or frogs;
  • Ant killer granules. This variety works best against ants but not much else. If your area has very little ant activity then this product is perfect for you;
  • Beetle killer granules. This variety works best against beetles and their larvae but not much else. If your area has very little beetle activity then this product is perfect for you;
  • Cricket killer granules. These work best on crickets and their larvae, but they do a poor job of killing off other types of insects (including ants). If your area has moderate to heavy cricket activity then these are the right insecticide granules for you;
  • Grasshopper killer granules. Grasshoppers will be attracted to these because it emits an odor that attracts them. It also kills off all stages of growth so there’s no chance of any eggs being laid and hatched;
  • Ant and cricket killer granules. This type of insecticide granule is a blend that works well on both ants as well as crickets, but it does not work against beetles or grasshoppers. If your area has an average amount of activity from all three types then this would be the best product for you;

The best lawn insect killer granules will work for all the types of pests listed above. The only way to know if they’re effective is by reading reviews from other customers and seeing what others have said about them or testing it out yourself.

Application methods

Some applications require spreading them with a spreader while others just require dumping them out in small piles near rocks and tree roots (since these pests will naturally travel there). It’s always better to purchase one that doesn’t need any tools other than a rake or shovel if you need to spread.

Application frequency

Some of these products work best when applied twice a year, while others can be used as often as once every three months (depending on the type). It’s important to find one that will compliment your needs so it doesn’t have time to build up and harm plants or animals in your yard that might feed on it. 

Volume/size of the product

Consider how big the bag is because this varies greatly depending on what product you go with. For example, a 25 lb bag would last about 100 days at two applications per season for an average sized lawn but only 75 days if they’re applying four times each year for heavy infestation problems. Make sure to plan ahead before purchasing and to do the math on how much time you’ll need.


Do insect lawn killers harm grass?

No, these products are designed to kill pest insects and not act as weed killers. The chemicals can be absorbed by the plant but will have no effect on their growth because they work in a different way than herbicides do.

How to spot an infestation in the lawn?

Some of the signs and symptoms to watch for include:

  • Moldy patches on leaves, turfgrass or other plants;
  • Damage caused by larvae feeding (grubs);
  • Creepy crawlers inching across your yard;
  • Dirt clods, mole hills or piles of dead leaves;

These symptoms can be a sign that your lawn has been invaded by insects – and it’s time to take action.

Are insecticides harmful for humans or pets?

Insecticides are typically formulated to kill insects so it’s important not to spray over your plants or food.

The EPA assures us that the insecticides sprayed in our yards are not harmful to humans or pets and is safe for use in residential areas. Most of these products are designed to be low-toxic by using a lower dose than what would normally cause an adverse effect on the target pest’s nervous system. In other words, if it kills bugs – it should be good enough for people! 

If you have any concerns about how likely your children (or animals) might come into contact with pesticides used outside, then make sure they don’t play around the area until after rain has washed away most of them. You’ll want to avoid spraying near any areas where they might be.

Some companies sell child-resistant packaging for some of their products if you’re concerned about young ones getting into them. Just make sure it’s labeled “pet safe” and that the EPA has certified its safety before purchasing a product!

Should insecticides be applied at a specific time?

Insecticides should be applied when the insect pest is most active. In warmer weather, this may mean early in the morning or evening to avoid contact with people and pets who are more active during these times of the day.  Pesticides can also be applied in the late afternoon or early evening to reduce exposure to children and pets.

When should you apply insect killer to your lawn?

The best time to apply insect killer granules is when the soil’s temperature has risen above 60 degrees Fahrenheit.  This is the time when insects have become active. The effectiveness of insect killer granules will be weakened if it is applied to a lawn that has recently rained or watered.

Can you put too much granular insecticide on the lawn?

To answer that question, you need to know the size of your lawn. If it’s only a couple thousand square feet and you’re using a pound or two of granules per application, then there is no limit on how much can be applied except for what works best in an individual situation. For example, if the area has been saturated with pesticides before (old chemical residues), you may want to use less than desired to avoid burning off new growth already sprouting from seed. 

If your lawn is much larger, a thousand square feet or more, and you’re applying pounds of granules at one time to infest the entire area with insecticide.

How long do Triazicide granules last?

The Triazicide granules last around 9 months. It’s recommended to reapply every six weeks or so, as this should be the lifespan for these types of insect killer products. The product is designed to help protect yards from insects like ants and different beetles that can become a nuisance in some areas with warmer climates where they thrive better than other places.

Should I water the lawn after insecticide?

It’s always best to irrigate the lawn after applying insecticide. This will help distribute it more evenly and also kill any pests that might be hiding in the turf. If you don’t water, or if there has been a prolonged drought period before application, then watering is not required but recommended.

Why you shouldn’t use pesticides on your lawn?

Although pesticides can be very effective, they’re also a risk to human health. This is because most are considered “persistent” compounds that don’t break down easily once applied and remain in the environment for years. As such, many of those who apply them end up getting exposed to them as well.

If you do decide on using insecticide granules or other chemicals though, it’s best not to shoo off pets from your lawn after spraying since their fur will likely absorb some of these contaminants too (although we recommend keeping dogs away anyways). Just make sure if you have children nearby that there isn’t any residue left behind by these products so their little feet won’t accidentally come into contact with it.
