Invasive Species Centre in Sault Sainte-Marie, Ontario. There is mention of chemical control of many species but usually in the form of painting a cut trunk or wicking in small areas. In the fact sheets I looked at, there were other more effective methods. There is extensive information of each species and extensive information of all control methods previously tried including biological. Also info on invasive plants, as well as invasive insects, fish and invertebrates, aquatic plants, and pathogens.
Viruses Shown to Be Effective Biological Control (Beyond Pesticides, November 30, 2023) Scientists at Minami Kyushu University in Japan have made a groundbreaking discovery of a new biological control for a target insect. They have identified a virus in tobacco cutworms that kills males, creating all-female generations. The discovery was described in a recent issue of the Proceedings of the National Academies of Sciences and The New York Times as evidence that multiple viruses have evolved to kill male insects... This “male-killing” virus could be added to the growing attempts to control unwanted insects with biological, as distinguished from genetically engineered (GE) solutions.
Eliminating Pesticides Increases Crop Yields, Debunking Myth of Pesticide Benefits (Beyond Pesticides, February 12, 2021) Recent research points to an example of such ecosystem efficacy. The study, by researchers in California and China, sought to evaluate whether increased population densities of fungi might be suppressing nematode populations in California production fields frequently planted with the cole crops (such as brussels sprouts and broccoli) they favor. The research finds that a diverse population of fungi in soils is highly likely to be effectively killing nematodes that threaten such crops. These research results demonstrate how faulty the use of fungicides — which in 2012 amounted to 105 million pounds in the U.S — is likely to be. These compounds destroy fungi that provide a variety of beneficial and economically valuable ecosystem (and crop) services. Fungi decompose and recycle nutrients, improve moisture retention, and even act as biological controls for some fungal diseases. Many other pesticides, including glyphosate (which is an antibiotic) threaten microbial life, as well.
Biological Management Has Added Billions in Benefits to Agricultural Economies (Beyond Pesticides, September 29, 2020) 'While the green revolution is often heralded in conventional agriculture circles as the key agricultural innovation of the last century, new research finds that biological controls likely had a bigger beneficial impact on world crop production. The success of these programs had critically important implications for agricultural economies in the region. “Biological control delivered durable pest control in myriad Asia-Pacific agriculture sectors, permitting yield-loss recoveries up to 73%, 81% and 100% in cassava, banana and coconut crops respectively, said Dr. Furlong.'
Good news for Canadian bees, other pollinators and gardeners – major garden centres shut down use of neonic pesticides (Friends of the Earth, 12 June, 2019) 'Top place for neonic-free flowering plants goes to two big box chain stores and one regional chain: Home Depot, Lowes (which includes RONA and Reno-Depot Corporate stores across Canada and Sheridan Nurseries in Ontario. As a close second, Canadian Tire Corporation reported that it has reached 95% neonicotinoid free. Home Hardware reports 100% neonic-free products from its distribution centres, but Friends of the Earth notes that many Home Hardware stores host local nurseries and it is not clear that their plants are neonic-free. Both Costco and Walmart report progress in removing neonics on their websites, but are not reporting on Canadian-specific markets. Loblaw, with the largest number of outlets – some 2500 in Canada – is recycling its 2016 statement saying that since 2014 it has been “developing a plan”. Empire Company, which owns Sobey, IGA, Safeway and other stores, has not responded to Friends of the Earth. '...there is no response from Atlantic Canada’s Kent Chain, Quebec’s Botanix Garden Centres or BC’s Art Knapp Plantland. Friends of the Earth hopes they will respond soon.' SNAP Comment: at least in Ontario. It has happened many times that, as pesticides got banned in Ontario. they were shipped West because we had no pesticide law yet. I hope the same isn't true for bedding plants. However, this is a survey so hopefully the companies answered truthfully. Always ask for neonicotinoid-free plants.
Coconut-Derived Insect Repellent More Effective than the Hazardous DEET (Beyond Pesticides, November 6, 2018) 'Scientists... have discovered natural compounds derived from coconut oil that are more effective than DEET at repelling mosquitoes, ticks, biting flies, bed bugs and other insects. Given the long-lasting efficacy of the compounds researchers tested, commercialization could make the regular use of toxic insect repellents, like DEET, obsolete. Scientists zeroed in on a blend of C8 (caprylic acid), C10 (capric acid), and C12 (lauric acid) fatty acids as the most effective repellent mixture. Individually, only C12 exhibited anywhere near the same efficacy as the specific blend identified.'

If you do a google search on ants, aphids, or any pest you are dealing with on the major websites I have listed in alternatives (NCAP, PANNA, or Beyond Pesticides), you can likely find other ideas and a much more complete answer.
Below is extra information on ants, aphids, bed bugs, cockroaches, fleas, grasshoppers, lice, mosquitoes and ticks.
