Natural Pest Control: Pros, Cons & Best Practices 2026

More and more clients ask us whether we perform pest control treatments with organic or natural products. The answer is yes. They also frequently ask about the advantages and disadvantages of these products. In this article, we highlight both sides and offer our expert advice on the best approach to repel insects—whether flying or crawling.

What Is Bio Pest Control?

For several years now, we have been performing pest control treatments using natural products. Specifically, we use an insecticide based on natural pyrethrum with B.I.A. (Low Environmental Impact) technology and low residual activity.

This is a concentrated emulsion with a rapid knockdown and flushing action, quickly effective against a wide range of insects—both crawling and flying. Common targets include: moths and beetles, tiger mosquitoes and common mosquitoes, sandflies, flies, wasps, and crawling insects such as ants and cockroaches.

Natural pyrethrum is carried by a glycolic solution (Low Environmental Impact Technology), which ensures greater safety during use and a lower environmental footprint. The product contains no aromatic solvents and is not phytotoxic when applied at the recommended rates.

Ideal Environments for Natural Pest Control

This type of treatment is ideal for sensitive environments where residual action is not required or desired: storage or processing areas for raw food or animal feed, food industries (food warehouses, grain silos, etc.), livestock facilities (animal shelters, milking parlors), indoor and outdoor spaces in civil settings (schools, canteens, tourist villages, campsites), commercial establishments (restaurants, hotels, shops, bars, etc.), and private homes (walls, paths, thresholds, windowsills, sidewalks, etc.). It is also suitable for vegetation treatment against mosquitoes (lawns, pathways, hedges, parks) and transport vehicles.

Disadvantages of Natural Pest Control

Due to its characteristics, natural pyrethrum-based pest control has no residual activity. What does this mean in practice? The main consequence is that the treatment must be repeated more frequently compared to high-residual products. Natural pyrethrum has a strong knockdown effect—it eliminates insects present in treated areas. However, it cannot prevent new insects from other areas from re-infesting the treated spaces.

Natural vs. Chemical Insecticides: Which Is Better?

The answer is not straightforward because both types have compelling features. However, in cases of severe infestations, we recommend chemical pest control due to its residual action, which protects the treated site for approximately 2–3 weeks.

We recommend natural pyrethrum pest control for sporadic infestations or in cases of allergies. For persistent raccoon problems, you may want to explore the best poison for raccoons as a complementary solution.

When to Choose Natural Pest Control

• Homes with children, pets, or allergy sufferers
• Food processing or storage facilities
• Schools, hospitals, and other sensitive public spaces
• Mild or occasional infestations
• Outdoor areas where chemical runoff is a concern

When to Choose Chemical Pest Control

• Severe or recurring infestations
• Commercial kitchens or warehouses needing long-term protection
• Structural infestations (e.g., termites, wood-boring beetles)
• When rapid, sustained knockdown is critical

FAQ

1. Is natural pest control safe for pets?

Yes, natural pyrethrum-based products are generally safe for pets when used according to label instructions. However, keep pets away during application and until the spray has dried completely.

2. How often should I apply natural pest control?

Because natural pyrethrum has no residual activity, treatments may need to be repeated every few days to a week, depending on the severity of the infestation and re-infestation pressure.

3. Can natural pest control eliminate cockroaches?

Yes, it can kill cockroaches on contact, but it will not prevent new cockroaches from entering. For heavy cockroach infestations, a chemical treatment with residual action is usually more effective.

4. Is natural pyrethrum the same as synthetic pyrethroids?

No. Natural pyrethrum is derived from chrysanthemum flowers and breaks down quickly in the environment. Synthetic pyrethroids are chemically modified to last longer, offering residual activity but with higher environmental persistence.

5. Can I use natural pest control in my vegetable garden?

Yes, natural pyrethrum is approved for use on edible crops and is not phytotoxic at recommended doses. Always check the product label for pre-harvest intervals and application guidelines.
