Should I fumigate?
 

I have seen and killed three beetles that are munching on most of my collection. They hide during the day, but i see all the nibbled parts in the morning. How and what should I fumigate with? My chids are in a closed off porch attached to my house. The beetles are black and about 1/2 in. long.:((. I don't have pictures because i snipped them in to tiny pieces.

Adult beetles are easily killed by most contact insecticides. Larvae may be inside the plants, so out of reach from contact poisons that will kill the adults. Get something in the permethrin family and drench your collection with that. Then treat with a systemic insecticide such as imidacloprid that will get into the plant to kill larvae that may be burrowing into the plants.

Revenge is a dish best served cold. If we had photos of the beetles somebody here could probably identify them and we would know where the larvae are hiding. That's hard to tell from little pieces.

I had earwigs a few years ago...the pitcher plant (sarc.) really loved when they tried to hide in its pitchers. I haven't seen any since.

A systemic for roses should be all that you need to get rid of the beetles.

Too funny. Anything that is caught eating my plants gets its head twisted off and fed to the pitcher plant!

Those Saracenas are unbelieveably efficient. The sundews catch a few flies, just small ones, but the Saracenas take everything. You may think they aren't doing anything, but look down the tubes, and you will find they are all half full of dead flies.

Or something....I usually cannot tell what mine have caught. The Butterworts recently took care of the latest fungus gnat problem. Only the leaves show that there was every any problem. The VFT are in their dormant stage but they get everything from flies and mosquitoes to spiders (from the looks of the legs sticking out of the traps). Yes, the CP's are useful to have around if you have other plants. :)

I also have sundews, butterwart, and a large pitcher plant. They do geat with the fungus nats.
I will try to get a picture if i catch another bug

I just got a couple of red sundews and yes, they seem to be doing their job quite efficiently. :)

Next, a butterwort, because they're just so sweet to look at. Like a tiny cabbage. Their carnivorous nature is just an added bonus! :D

Here is picture of the little bugger.

That's some type of weevil. Here in the UK they are a pest, the adults eat semi circular holes in the edge of the leaves, but it is the grubs that cause mst damage eating the roots of plants and causing the death of many pot plants. There is a specific pesticide for vine weevil that is used as a soil drench, I don't know if there is one in the USA. The grubs are cream coloured and 'C' shaped about 1 inch long and can be found in potting media or outdoors in the soil.
