Since the last few weeks a few crawlies that look like a centipede are infesting my home vegetable garden patch and are multiplying in large numbers. We have tried using organic solutions like Neem Oil and Onion Water but they just don't seem to go away. They're not eating out plants yet but infesting nearby plants at an alarming rate. Since this is a vegetable garden we do not want to use any harmful chemicals. Can you please give suggestions as to what to do to get rid of them ?
I see that your soil is very compact clay. They probably made their way in while being dug up. Generally, clay soil is not recommended because it is too compact and will not drain properly in container. Potting soil is necessary in this case, and clay soil will cause damage, where the centipedes will not. Centipedes prey on insects that DO harm you plants, though. If there are quite a few of them, then I'd look at there being actual pests in the soil.
I think that the fix here would be to change the clay soil to potting soil. This will rid the centipedes. After this you can treat the underlying cause.
I do see signs of spider mite damage. This would explain the heavy centipede population. Treating for that is usually neem oil, though.
In my opinion, potting soil should be seeding with the centipedes, and the extract of neem oil, azadirachtin should be used every few days, or weekly, to control the mites.
Introducing predatory mites can help, too.

can i make a safe insect spray.
Making your own is not always the best option. Even insecticidal soap is more predictable if purchased. If a spray is needed, it is best to start with the least toxic product. These articles should help:

Are BTI drops safe for indoor plants if so how can I order the drops?
We don't recommend certain brands or vendors, but here is more on getting rid of fungus gnats, including Bti, which can be purchased as dry bits at big box stores or online. Applied to the soil, when you water, it releases the bacteria into the soil.

There are marks all over the foliage of several of my plants… my dahlias, catmint, and salvia most noticeably. I can’t figure out what’s causing the spots and if it’s the same thing for all of the plants or if maybe my dahlias are suffering from something different than the catmint and salvia. The new growth appears healthy and then becomes marked later. The catmint and salvia seem to be blooming normally. The dahlias have several buds, but their flowers do not look healthy. Any ideas on what this might be and how I can help them?
These seem to all have the same problem. This is spider mite damage. You might notice tiny red mites crawling on the plant. They like the undersides of leaves, so look there. This is the worst problem that I have in my indoor garden since there are no natural predators to eat them. Outdoors you could introduce predator insects to eat them, like predatory mites. I wouldn't advise that indoors, though.

Treatment needs to be consistent. They seem to take whatever you throw at them. Azadirachtin is an extract of neem oil. This is what I recommend.

Something safe for pets
Since there are no good chemical means the best way would be a trap.

You could introduce beneficial insects to the area and keep it cleaned of debris.

hello, i recently added a mid sized perennial garden to the walkway path to the front door and noticed a lot of activity with hornets and wasps. i know they are pollinators and helpful to the environment but i am very afraid of going outside and doing any garden care in fear of being stung. have read online they dislike the scent of some herbs. would it be beneficial to plant some in or would the smell also discourage bees and butterflies and birds? thank you!
Artemisia, mint, citronella, and eucalyptus are plants that are reputed to deter bees and wasps.

I have in my garden, several plants. Some of them have leaves that are being chewed and I don't know what kind they are or how to get rid of them. The plants are zinnia, sunflower, echinacea and bell pepper leaves. Please let me know if you have a remedy. Much appreciated. Thank you.
There are chewing insects as well as piercing-sucking insects. Examples of chewing insects are grasshoppers, beetles, and caterpillars. Piercing-sucking insects include aphids, scale, and mites. These articles may help you identify the culprits:
