What is killing my marigolds?

Every year I plant marigolds around my lamp post. In the last two years, something kills them. It looks like spit on them. I’ve sprayed them, put Seven dust, nothing works. For years they grew well there. Any suggestions?

Probably slugs or snails which leave a slimy trail, also they are night feeders. Put down snail bait which attracts and kills them.
Try a different annual this year plus dig out the surrounding dirt and replace some of it.
Hi there,
Try using PROVADO Ultimate Bug Killer. Available in stores or online. Sounds like Cuckoo Spit!
Sand or eggshells...snails and slugs won't cross. Be sure to spread out a few inches.
There are bugs called “spittle bugs”. They are actually green & enclosed in the spittle. Pretty easy to just smoosh them, but soapy water kills them too. I hate poisons, so I always try soapy water first in a spray bottle. Just warm water with a dash of dish soap. I prefer Dawn. Shake & spray. Do it @ the very least every 7 days.
The problem could also be male dogs peeing on the plants? Could that be an option? Good luck!
Sheila is right on target!
You could manually remove them by splitting open the spittle and taking out the contents. Soapy water gets rid of them, just spray when needed. Also remove any debris that maybe around your marigolds.
Use pure Neem oil it is non toxic to plants,animals,soil so it will not kill bees; be sure to spray underside of the leaves as well that is where the bugs stay/hide out not the top sides,do stems too.

Adult and juvenile spittle bugs on a casuarina
Spittle bugs are interesting insects that produce a white frothy substance on stems and leaves which looks just like spittle. Hidden underneath that froth is the juvenile busily sucking out sap from the plant. The froth serves to protect the juvenile from adverse weather conditions and predator attack.
Adult spittle bugs are about 1cm long and don’t produce the froth. They are called froghoppers and are incredibly strong jumpers which helps them avoid predation.
Even though spittle bugs suck sap from plants they rarely cause any damage and aren’t regarded as problem pests. Usually they only occur in small numbers so again plants are not significantly impacted.

If a large number appear on a plant or you just don’t like the look of the spittle then you can:
