Earlier this week, I was experimenting on whether lizards are afraid of eggs. I observed for a few days and was quite disappointed with what I saw. I finally decided to take a photo and conclude this experiment.
Are lizards afraid of eggs?

Look at that photo and answer that question yourself. However, I cannot say for certain that the “egg trick” doesn’t work on lizards. I have read others saying that it did work for them. The reason it didn’t work in my case could be due to some “unknown factors”.
What could have caused this experiment to fail?
- The lizards did not see the eggs.
- The lizards didn’t know those were eggs (bird/chicken).
- The lizards dare to fight back and maybe even bite any birds that may fly by.
- The lizards are smart enough to know that birds cannot enter through the small opening in the window.
Conclusion
I can’t say for certain that lizards dare not appear in places where you put an empty egg shell. It did not work for me but it could have or could still work for you.
If you have tried it before, did it work for you? If you haven’t, would you please try it and share with me if it worked? Thanks.

I thought it was supposed to be chicken egg shells?
@Angie Tan
Yeah, I used empty chicken egg shells.
maybe the lizard is blind? perhaps… then the theory still is valid.
@lazyfellow
LOL. Not sure if lizards can be blind or not. I think it is either the gap in the window is too small for birds to fly in or lizards are not afraid of chicken egg shells. Maybe it just didn’t work in my situation but will work in others? I not sure.
Well, you are focusing only on one of the senses lizards have got i.e. sight. Lizards may not like the smell of eggs!
I think you should place hollow egg shells there. It is highly probable that the odour of eggs drives lizards away. Don’t use hardboiled egg shells as they have no odour.
I guess they should be broken chicken egg shells and not boiled eggs
Those are not hard boiled eggs. We broke the tip of the eggs and “drained” all the contents out. Of course, it was washed before we placed it there. We don’t want trouble with the ants! LOL.
some say its the inside substance of the egg shells that repels lizards..i dont think small holes that you made were big enough..the best way would be to ‘cut’ the whole egg shell into halves..n its okay to rinse them..but not to wash them thoroughly..the chemical substance might be washed off..n of coz u would have to change the egg shells occasionally..once a week or once a fortnight would be fine..
Egg shell content a sulfur. Sulfur is very harmful to the lizard. This is because their abdomen have pores, so when they get near to sulfur it will getting dry and sometimes it will burn itself. These also will answer why they afraid of beak animals such as bird. Their beaks also content sulfur. The lizard will sense the odor which a human being cannot smell it.
I did read somewhere that there’s gotta be a little egg white left in the shells. Mine seems to be working. No ants too
hi! my friend tried that too, actually she was so afraid of lizards that she used to put the shells all around her house, almost all the corners of her house were occupied by egg shells.. but unfortunately that did not work for her at least…i dont know the reason. where as i use sprays to get rid of these filthy creatures, for me spraying over them is the last resort that actually works. I use KINGTOX, thats the best one for killing lizards, it freezes them where they are though the smell is extremely irritating, if u get allergic u may end up sneezing but thats ok if u want to get rid of them.. cheers
