Frequently Asked Questions

What is diatomaceous earth and how does it repel ants?

Diatomaceous earth (DE) is a natural product made up of fossilized remains of tiny, aquatic organisms called diatoms. It is a non-toxic powder that makes an excellent pest control for ants. Ants and other bugs ingest the microscopic sharp particles when they come in contact with DE, which then damage their exoskeletons and cause them to dehydrate and die.

Can I use these methods to repel other types of insects?

Yes, many of these methods, particularly the use of plants, herbs, and natural substances, can also repel other types of insects. For example, mint, lavender, and marigolds are known to deter a variety of pests. Similarly, diatomaceous earth is effective against many types of crawling insects.

How often should I apply these ant repellents?

The frequency of application depends on the severity of the infestation and the method used. Natural repellents like essential oils and vinegar may need to be applied more frequently, such as once a week, while commercial ant killers may provide protection for up to several months. Always follow the instructions on the product label for best results.

Are commercial ant repellents safe to use around pets and children?

Not all commercial products are safe for use around pets and children. It’s important to read the product label and safety information before use. Some products may require pets and children to stay away from the treated area for a certain amount of time.

Why do ants invade my yard?

Ants are attracted to your yard for various reasons, including the presence of food sources (like sweet spills, pet food, or garbage), water sources, or shelter (like mulch or plants). They may also be attracted to certain types of plants or other insects in your yard.
