Yep, roaches. I saw this bag of roaches when we were out checking out Halloween decor and I just knew it was gonna be perfect. There is nothing grosser than a roach! Its gross when its alive and its gross when its dead. And boy was I right! Dumping a bag of these (fake) roaches into a batch of clear slime even freaked out my 6 year old son.

It doesn’t matter if you make a nasty black or green slime, but we preferred making a clearer slime so the roaches could bleed through it.

It reminded us of them being squished!

ROACH SLIME Ingredients

Most slime have the same ingredients, depending on whether or not you are using clear glue or white glue, saline solution or starch, no matter how you make slime, its always a lot of fun. For this homemade roach slime, you need the following:

How to make Roach Slime

Start with your clear glue. Pour approximately 1 cup in a bowl. We wing this and do not measure, its not important to be perfect.

Now add saline solution – start with approx 1 tablespoon and stir.

The slime will start to form.

You can adjust the amount of saline solution you add to make it more or less sticky. We were pretty happy with our dripping slime but in this case, to make it more solid, we also added a bit of liquid starch.

The liquid starch will take your perfectly clear glue and make it a bit cloudy.

The more you add, the less sticky your slime will be. Start at 1 tablespoon and go up slowly, making sure you kneed your slime all the way through before adding more.

Once your slime is done, add your roaches!

You can also add your roaches into a beaker if you want to set them up as Halloween Decor at a party! There are so many ways to freak out with this slime.
