Soil traps

And I have on Rublyovka Dorcadion for 2 hours put 120 traps With a brew, but without a lid. It was already dark...

Don't kill the last beetles on Rublyovka.
In Pakistan, putting 120 glasses is healthier. Sorry, friend Omar, cry of the soul.

no, we didn't catch all the beetles, just a little bit of the most interesting stuff ) Rublevka didn't suffer

and the karabusy oligarchs didn't get caught? they are not uncommon there.

we left traps for 1 night, and oligarchs go during the day

I am constantly confronted with the facts of" withdrawal "of cups by "competitors" (squirrels, magpies, crows). Of course, och. cynically-to wish that these squirrels would have paws... I won't say that, but, mb, somehow you can fight this? I'll bury the cup, and she (I won't say who) - squirrel will pull it out and throw it away from the hole, carefully dug by me. What should I do? I'll bury it again, and she'll bury it again. It looks like the work of Sisyphus ... Help-help-help!

Try the fishing option. Proposed by L. Rybalov (IPEE RAS). He uses juice bags in the permafrost zone - the usual "Tetra-Pak'i". They, like cups, do not "stick out" over time - they only deform, I don't care what - they are disposable! Maybe your (I won't say which) squirrels can't handle it. Birds, for sure...

Yes! Do not forget the bags, after inserting them into the ground, thoroughly "tap" the inside with your hand - so that they take the shape of the hole you have prepared and "stand" there tightly. Such traps full of insects and arsenic in Tuva were taken out by bears - and they did not always succeed, as it is not surprising!

A couple of years ago, I had the same problem with crows and magpies-they pulled out glasses and smeared the contents in an even layer around. They worked brazenly, somehow all the glasses were pulled out half an hour after installation. As a measure of struggle, I took the following action: I put a stick on the glass, pinned it on both ends with flutes, and made another twig across this stick. Thus, the glass on top was covered with two crossed sticks. It seems to be complete nonsense, but oddly enough it helped-the pogroms stopped, apparently such a crosshair causes vranovs some bad associations with a cunning trap, Whether this will help from squirrels I don't know, I'm not sure...

Probably helps with outrages. But if there are 100-200 traps, it will be difficult to build a similar one for each of them.

You can take with you a certain number (how many glasses or widow's more) of wire rods in the form of P (only with a wide upper stick and short side ones) and use them to fasten the cups according to the Anthrenus method, a. do not waste time searching for twigs, etc.
