Da ce cauta bre tantari la Deva?

Cum ce cauta? sunt pe aici dintotdeauna

restul sunt veniti in vizita. Daca-l alungi/omori pe ala ai scapat de problema

Da si apoi vin ailalti la inmormant are...

Nu cred ca-s unguresti, sunt riverani, e multa vegetatie , plus lunca Muresului..am inteles ca se inmultesc prin pomi

Primarele tot promite ca stropeste, dar e prea ocupat cu afacerile pe bani publici

Sa sti ca doar tantaroaicele "suge"sange, tantaroii doar bazaie, da asta nu ced ca te ajuta prea mult...Raidul la mine avea efect atunci cand era nevoie...acuma stau cu geamurile deschise . Serios incearca cu Raid...si pune si plase la geamuri

Am luat ieri de la Plus un set de aparate din astea, unul ptr interior, alimentat la 220V si unul de exterior, alimentat de o baterie 1,5V.

Aseara l-am testat pe cel de interior. O mare PORCARIE. M-au halit tantarii la greu, pana m-am sculat si am pus o pastila in aparatul obisnuit.

Ma gandesc ca si cel exterior o sa aiba acelasi efect...
26 lei aruncati aiurea. Imi pare rau ca nu mai am bonul, sa-mi cer banii inapoi.

Ultrasounds myth busted!

Am vazut si eu odata unul dinala de prajeste tantarii, zic ca e eficient. Il bagi cu 1h iainte sa dormi, ii prajeste pe toti si gata.

Argon, tu plase la geamurile pe care el tii deschise nu ai?

@St, ala e alt aparat...
Lumina ii atrage pe tantari si se curenteaza. Da, ala e intr-adevar eficient.
Insa eu vorbeam de unul cu ultrasunete, care teoretic i-ar deranja pe tantari la ureche, dar se pare ca astia ai nostri sunt cam surzi...
Ma interesa in mod special varianta de exterior, portabila...

Stiu ca tu vorbeai de ala cu ultra-sunete.
E clar ca tantarii de pe la noi stau cam prost cu auzul..

Sau poate tantarii romanesti intra in rezonanta la alta frecventa decat aia pe care a fost testat aparatul! Cainii sunt deranjati de el? Al meu caine pe la 22 000 Hz devine atent, dar nimic mai mult.

Do Ultrasonic devices work?
At least 10 studies in the past 15 years have unanimously denounced ultrasonic devices as having no repellency value whatsoever. Yet, consumers flock in droves to hardware stores to purchase these contraptions. Why? The discovery that mosquitoes locate mates in mating swarms via wing beat frequency generated a great deal of research into ultrasound as a potential source of environmentally-friendly control. Yet, all attempts to affect mosquito behavior by ultrasound have fizzled, despite enormous amounts of money spent upon research and development. To be sure, the clever, high-tech, and imperceptible (by humans) use of ultrasound proved to be an exceedingly effective marketing tool for the repeller manufacturers. Homeowners were urged to buy ultrasonic repellers and the like to rid their houses of pests without the need to inhale "even one breath of poisonous spray". This appeal to the public's chemophobia, while extremely effective in diverting attention away from proven preventive and control measures (and toward their repeller products), has undermined an unbiased review of the subject by consumers desperate for a clean, effective, nonchemical means of mosquito control. Unfortunately, no such miracle cure exists. A pioneering study testing five different ultrasonic devices against four mosquito species convincingly demonstrated that ultrasound in the 20-70 kHz range used by these devices had no effect on reorienting flight by female mosquitoes either toward or away from human subjects. Additional tests have shown that sound generators capable of a wide range of frequencies were also ineffective in repelling mosquitoes. The fact is that these devices just do not work - marketing claims to the contrary.
