Oh yeah! You are going to LOVE this! I have a new security system that is absolutely one of the best, and one of the nastiest you can get...and,..... it was absolutely FREE! That’s right, FREE! Can YOU believe that? No one, not even an animal can get past my newest "security system"! I guarantee you that it is one of the finest made and it never really sleeps 24/7. It will stop almost any animal, except maybe: a water buffalo, an elephant, a rhino or an alligator/crocodile. This has the fastest and most dangerous and cantankerous bunch of safeguards you have ever seen! Now it does have a few drawbacks: 1) cold weather makes it a bit sluggish and somewhat inoperable... 2) NO one, not even the owner of the property can enter after the "unit" has installed itself! Oh, did I forget to mention that this security system is not only "self installing", it is "maintenance free", and never needs feeding, or watering, or batteries, or any other power source? And it's just as well too! NOW, How's that for security? It just never quits.... It can however grow to an enormous size, and can become a real hazard in a short period of time. The few drawbacks are somewhat bad.... The stings! The Yellow jackets will attack when you are within 20 feet of my utility trailer! Try to open the door! The "former" caretaker did...he was stung 5 times in the hand that touched the door knob and twice in the neck.... He ran as fast as he could, around a corner to his front door yelling to get out of his way and to get the dogs inside, the yellow jackets were attacking...! They held him and 3 dogs at bay, inside his trailer for over half an hour! Now that's what I call "REAL SECURITY"! I know...I got nailed by one of them nasties a few months back and I still hate to think about it. I was quite a ways away, saw a yellow jacket sitting on the roof, and before I could move I was attacked by the danged thing! He stung me in the back in the shoulder area and it felt like a red hot ice pick was stuck in me! I used 4 cans of jet spray for hornets/wasps and 2 cans of WD-40 before I was able to get the door opened ( early in the morning when it was really really cold), rip out their nest, spray another dozen or so workers and guard hornets, or whatever they are ( mean and nasty is what they are!) then throw the nest on the ground and set it on fire. That stopped them! Well, for about 5 minutes anyway...then the rest showed up and the WAR was really on then! They are very persistent! I fought them from starting a new nest for at least 4 days afterwards...they just kept coming. I killed so many that I lost count and that nest was only about 4 inches around. Now it seems they have returned....Oh well...at least I know NO ONE will be going into that trailer for awhile! NOT even ME! So much for needing batteries, solar power, gasoline, or propane! Personally, I think those things are powered by the DEVIL! WARNING: This Property is protected by: INSECTS FROM HELL! ( I like it already!) I wonder, ya think we could package them and sell this? I know it works! I have seen it, I have felt it, and I HATE them thar varmints!
