Do Roaches Like Silicone?

Silicone is often used to block up gaps and cracks around pipes, windows, and basements in an attempt to keep pests out. But could your silicone caulk be doing more harm than good by actually attracting roaches to your home?

The answer is: no.

Do roaches like to eat silicone?

There is no evidence to suggest that silicone attracts cockroaches. Generally, roaches are attracted to:

  • Food sources
  • Water sources
  • Warmth
  • Harborage sites (areas where they can hide or nest)

As a type of rubber, silicone has no nutritional value, so cockroaches won’t eat it – nor will they be attracted to it.

In fact, silicone should be one of your closest allies in the war on roaches! Silicone caulk is a highly effective tool for keeping cockroaches (and other types of pests) out of your house.

How to use silicone against cockroaches

Keeping your home pest-free is all about prevention, and one key aspect of this is making sure all entry points are sealed.

Inspect the exterior of your house for gaps and cracks, paying special attention to the areas around pipes, drains, windows, doors, and basements. Once you find a hole, block it up – immediately!

Duct tape can be a great short-term fix but, if you want a more permanent solution, opt for a silicone-based caulk or filler. Silicone sealants last at least 20 years so, once installed, will help to prevent infestations for years to come.

Other ways to prevent cockroach infestations

Silicone sealant should be used as part of an integrated pest control plan to effectively keep cockroaches away. For maximum protection against pests, you should also:

Keep your kitchen clean

Roaches may not think much of silicone, but they are highly attracted to food. To avoid drawing them into your house, make sure all crumbs, spills and dirty utensils are cleaned up immediately.

Store your food securely

Store all food in sealed containers or the refrigerator to avoid attracting roaches.

Manage your trash well

Cockroaches love garbage, especially if it contains food scraps! Make sure to empty your kitchen trash regularly, and dispose of this outside in a receptacle with a sealable lid.

Finally, keep your garbage cans at least 6 feet from the exterior of your house.

Remove harborage sites

Shrubs, long grasses, leaf litter, firewood piles, empty boxes, recycling, and other clutter all make great hiding places. Cockroaches are more likely to make nests where they can shelter easily, so if there are lots of harborage sites around your house, get to work clearing them away!

Remove moisture sites

Roaches are attracted to areas with a steady water supply, so moisture sites around your home may tempt them in. Look for damp areas under leaky faucets, AC units, and in your basement, and dry them up as soon as you find them.

Conclusion

Roaches are not attracted to silicone; in fact, this rubbery material can be very useful for keeping them out! A silicone sealant can effectively block potential entry points around your home, reducing your risk of infestations from roaches, rodents, and other types of pests.
